A DoD Information Analysis Center Sponsored by JANNAF and DTIC Vol. 35, No. 3 May 2009 News and Information for the Greater Propulsion Community Propulsion Research Activities Abound at Auburn University By Dr. Winfred A. “Butch” Foster, Dr. Roy Hartfield, and Dr. Brian Thurow Auburn University, Auburn, Alabama A uburn University’s Aerospace Engineering Department is the site of many activities related to the propulsion of aerospace vehicles. The study of propulsion systems at Auburn began with the creation of the aeronautics curriculum for the 1931-1932 academic year, and the first graduates finished the program in 1933. Instruction and research associated with aircraft and rocket propulsion have been an integral part of what is now Aerospace Engineering. While coursework related to propulsion had been in the curriculum since its inception in 1933 and specific courses dealing with air breathing and rocket propulsion had also been added over a period of years, it was the 1966 arrival of Richard Sforzini, a Morton Thiokol solid rocket motor specialist, that marked the beginning of a major emphasis on propulsion, both in the academic curriculum and as a major research topic. In 1967, two new rocket propulsion courses covering liquid propellant rockets and solid propellant rockets were introduced into the undergraduate curriculum as electives. Both courses provided a foundation for the preliminary design and performance analysis of rocket motors. In the early 1970s, because of the intended use of solid rocket motor boosters on the Space Shuttle, NASA’s Marshall Space Flight Center (NASA/MSFC) needed to provide training in the area of solid rocket motors to engineers whose continued on page 4 Purdue University Promotes Propulsion Education and Research through Unique Testing Facilities By Dr. Steven F. Son, Purdue University, West Lafayette, Indiana P urdue University has a long tradition in propulsion research, and its unique facilities enable hands-on education in combustion and aerospace sciences. A significant part of propulsion testing facilities at Purdue are located at a remote location, away from the main part of campus, on a 24-acre site adjacent to the Purdue University Airport. Rocket propulsion testing at Purdue began in 1948, under the direction of Dr. Maurice Zucrow. The Advanced Propellants and Combustion Laboratory (APCL) houses two control rooms and three test cells (Cells A, B, and C) for propulsion testing, fuel coking studies, and propellant development. Another rocket test cell (Cell T) is now operational in the Propulsion Laboratory. Test firings are conducted and observed from the control rooms. In addition, there are several small-scale experimental labs throughout the Zucrow complex. continued on page 6 JANNAF Propulsion Meeting & Joint Subcommittee Meeting held in Las Vegas – See page 12 Inside This Issue JANNAF Subcommittees to Convene in La Jolla, CA ..........................................3 Johns Hopkins University Sponsors 6th Annual Physics Fair..............................9 CU-Boulder Develops Drag and Atmospheric Neutral Density Explorer .....10 JANNAF Meets in Las Vegas..............12 JANNAF Journal Vol. 3, Call for Papers...16 Two Successful Motor Test Firings in Support of IHPRPT............................17 In Memoriam Frederick A.

University continued from page 1 background had historically been limited to liquid propellant rocket engines. NASA MSFC chose to use an expanded version of the solid rocket motor course being taught at Auburn for this training program, and it was taught onsite on two occasions. Additional and expanded graduate courses in propulsion were introduced beginning in the late 1960s. The vast majority of research at Auburn in the area of rocket propulsion has been related to performance prediction, preliminary design, and optimization of solid rocket motors. The modeling and optimization effort has been supplemented by experimental investigations in facilities on campus and at NASA/ MSFC. Liquid rocket and air breathing propulsion research has included preliminary design and optimization of ramjet and scramjet combustors and ramjet- and scramjet-powered vehicles, nonintrusive, instream measurements of critical flow parameters in nonreacting combustor geometries, and the ongoing development of advanced measurement diagnostic techniques. The research areas at Auburn are varied and cover many of the major areas of interest associated with both rocket and air breathing propulsion. Several of the individual research activities at Auburn are described in the following sections. Solid Rocket Motor Performance and Design Solid rocket motor research activities at Auburn University have been ongoing for the last forty years. This research has been primarily directed at the development of analytical tools for solid rocket motor internal ballistic analysis, optimization of solid rocket motor powered missiles, and structural analysis of solid rocket motor hardware. One of the earliest major efforts began in the early 1970s to support NASA/MSFC efforts to evaluate the internal ballistic performance of the Space Shuttle’s solid rocket motor boosters. There was a need at NASA/ Page 4 MSFC for a computer code that could be used on relatively small computers, which would be able to match results from more sophisticated internal ballistics codes to within 5% for such variables as thrust, specific impulse, total impulse, etc. A so-called simplified internal ballistics computer code was developed to meet these objectives. In fact, this code was accurate to within 3% in general and to within 1% for certain parameters. It formed the basis for much of the work done at Auburn over the next 15 years. This work included a Monte Carlo thrust imbalance prediction code which utilized 41 variables for the Space Shuttle solid rocket boosters. The simplified code also served as the basis for the development of design and design optimization codes based on a pattern search technique for solid rocket motor preliminary design. Other uses of the simplified code include studies of off-design performance and reverse engineering analyses to evaluate motor characteristics based on flight or test data. An expanded version of the simplified internal ballistics code, the Solid Rocket Motor Multiple Options Program, included the capability to account for propellant grain deformation effects, circumferential grain temperature distributions, and the effects of circular perforated grain ovality and centerline misalignment. These last two effects are not known to be accounted for in any other internal ballistics code today. On two occasions, experimental efforts have been conducted at NASA/MSFC to obtain a better understanding of the flow field induced by an igniter in the head-end star grain slots. This work included the design and fabrication of 1/10thscale models for the reusable solid rocket motor (RSRM) and advanced solid rocket motor (ASRM) head-end star grains. Measurements included oil smear data, pressure data, heat transfer, laser doppler velocimetry data, and flow visualization data, using aluminum particles to seed the flow. Igniters with both single- and multipleport configurations were evaluated. A subset of these experiments included an effort to evaluate plume interactions for multi-port igniters. The model used for the slots along with the igniter models tested for the ASRM are shown in Fig. 1. Figure 1. Model used for the slots and igniter models tested for the ASRM. Scramjet Combustor Design The study of fuel-air mixing in a supersonic cross-flow has been investigated extensively as a test case for a scramjet combustor geometry. With the development of computing technology, it is possible to develop optimized preliminary designs for scramjet combustors using a computational fluid dynamics (CFD) solver and a Genetic Algorithm (GA). Experimental results from research conducted in the 1990s have been used for the validation of the CFD solutions. The experiments were highly focused on developing accurate data sets for a single-case flow situation. This effort builds on this single validated case by considering geometric variations of the combustor design, solving for the flow, and arriving at a geometry which is optimized for mixing efficiency with minimum total pressure loss under the direction of a GA. Sample results for the validation case are shown in Fig. 2. continued on page 5 CPIAC Bulletin/Vol. 35, No.3, May 2009 Auburn University.... University continued from page 4 Figure 2. Sample results for the validation case. Figure 3. Optimized solid boosted ramjet missile system (left) and an aerodynamically enhanced launch vehicle (right). Rocket and Ramjet Propelled Vehicle Design Recent vehicle design optimization efforts have focused on multiple-stage solid propellant vehicles, single- and multiple-stage liquid propellant vehicles, solid motor boosted ramjets, and solid motor boosted scramjets. Successful demonstrations of a two-stage all-solid propellant-kinetic weapon system and a solid motor-boosted air breathing vehicle have supported the U.S. Army’s mission to develop advanced weapon systems. A substantial program to develop solid propellant-fueled launch vehicles has resulted in an optimized version of the minotaur launch vehicle and vehicles that include enhanced performance using aerodynamic lifting during early flight. During this effort, the performance of the basic wingless vehicle was found to be enhanced by varying the geometric definition of the attached wing structure and the internal propellant. Initial system weights and propellant mass fractions were found to decrease for a given payload even with the addition of the wing structure. Figure 3 shows representations of an optimized solid boosted ramjet missile system and an aerodynamically enhanced launch vehicle. Diagnostic Technique Development for Propulsion Flows Recently, researchers at Auburn have been developing high-speed advanced laser diagnostics suitable for measurements in high-speed and/ or reacting propulsion-related flows. The centerpiece of this development is a home-built pulse-burst laser system capable of producing high energy Figure 4. 3-D imaging technique used to visualize (>10 mJ/pulse) laser pulses at repetition rates exceeding 1 MHz and flow of a turbulent jet. wavelengths ranging from 266 nm to 1064 nm. Used in conjunction with a high-speed camera capable of 500,000 fps, the laser can be used to take high-speed flow measurements using techniques such as planar laser-induced fluorescence to simple flow visualization. Perhaps the most unique application of the system, however, has been for the acquisition of 3-D flow images. For 3-D imaging, a galvanometric scanning mirror is used to scan the high-repetition laser sheet through the flow field with a high-speed camera recording the image at each scan location. A 3-D image can then be reconstructed from the stack of 2-D images. The overall acquisition process can be completed in tens of microseconds. An example of the technique used to visualize the flow of a turbulent jet is shown in Fig. 4.

CPIAC Bulletin/Vol. 35, No. 3, May 2009 Page 5 Purdue University.... University continued from page 1 Gelled Propellant Lab (GPL) The GPL is Purdue’s newest propulsion laboratory being developed in support of an Army Research Office (ARO) Multidisciplinary University Research Initiative (MURI) program on spray and combustion of gelled hypergolic propellants, which was awarded last year to Purdue and its partners. The GPL houses a control room and a laboratory space dedicated to small-scale testing with hypergolic propellants such as NTO, IRFNA, and hydrazine-based fuels. The versatility of the mechanical and data acquisition systems as well as the dedicated air ventilation and monitoring systems installed at GPL make this laboratory particularly well-suited for testing of hypergolic systems and fire/vapor suppressant systems, as well as other small-scale experimental activities. LOX-LCH4 Facility The LOX-LCH4 facility is being developed to provide a known-temperature liquid cryogenic fluid to a test article. Standard gaseous oxygen and methane cylinders are used to supply pressurized gases into cyrogenic chilling tanks to produce and store liquid propellants for test operation. Each system can be independently temperature-controlled with a goal to deliver specified temperature propellants to the test hardware. The facility is designed to test smallscale thrusters and ignition work in addition to fundamental instability research of LOX-LCH4. Solid Propellant Mixing and Combustion Lab Purdue’s solid propellant mixing facility utilizes a Ross model DPM-1 Quart double planetary mixer that has a mixing range of ½ pint to 1 quart with stirrer speeds of 22-98 rpm with cooling or heating control, and vacuum to about 0.5 psia. The Ross mixer can be operated remotely from a control room. The facility includes two windowed pressure vessels (Crawford bombs) for combustion studies of propellants and energetic materials. Pressures up to 6000 psi can be considered. Sapphire windows allow access to infrared access, and a top window of one of the vessels is configured for the use of a Zinc Selenide (ZnSe) top window that allows ignition studies using a CO2 laser. High-speed digital microscopic imaging and visible/IR spectroscopy are used in combustion studies. Electostatic discharge (ESD) and impact testing is used to quantify sensitivity of new propellants. Material ball milling, cutting, and polishing, along with microscopy, are also available for sample characterization. An environmentally controlled glovebox is used to keep nanometals pristine. A light gas gun, explosive blast chambers, and initiator testing facilities are also currently used. Purdue also maintains active Class 1.1 and 1.3 bunkers for remote storage of energetic materials as part of the Zucrow Laboratory complex. Many other small-scale laboratory research projects are also located at Zucrow Labs, including hydrogen storage, combustion, spray dynamics, and fluid dynamics. High Pressure Lab (HPL) Originally constructed in the mid-1960s in support of the Apollo program, HPL provides the most substantial capabilities for rocket and airbreathing combustion and nozzle studies with two large test cells classed to 10,000 lbf thrust levels. A 6000 psi nitrogen system serves for pressurizing facility tanks, and 5000 psi liquid oxygen, gaseous hydrogen, kerosene, hydrogen peroxide, and cooling water capabilities exist to the 10,000 lbf thrust level. A gas-fired heat exchanger provides airflows heated to 1000Ο F at flowrates on the order of 10 lb/s to simulate airbreathing combustor inlet conditions, and roughly 5 tons of high-pressure air storage is available from the lab air system. There are also several unique large-scale testing facilities at Zucrow Labs. Pulse denotation and high-pressure gas turbine combustor test rigs are currently in place at HPL. The airbreathing combustor rig provides optical access for diagnostic access to the combustor. The HPL Annex is the newest building within the HPL complex. This 1400-sq ft structure provides large continued on page 7 Figure 1. Hydrocarbon film cooling test on 10 klbf thrust stand at Purdue High Pressure Laboratory (left). On the right, is a fitted heat flux measurement for a HO combustor. Different lines within each pressure grouping refer to measurements at different azimuthal locations. Page 6 CPIAC Bulletin/Vol. 35, No.3, May 2009 Purdue University.... University continued from page 6 flow capabilities for airbreathing combustion and nozzle experiments (see Ref. 1 for details). In the past decade or so there has been a reinvigoration of the facilities and increase in personnel at Purdue directing efforts in propulsion, as well as in related areas of energy and combustion. Additional details about the facilities can be found at https://engineering.purdue.edu/AAE/Research/ ResearchFacilities/LabFacilities, https://engineering.purdue. edu/Zucrow/index.html and in Refs. 2 and 3. Current Research Topics Research pertaining to propulsion is inherently multidisciplinary and therefore includes elements from numerous organizations within the Schools of Engineering and Science at Purdue University. More than a dozen professors, specifically within the Schools of Mechanical Engineering (ME) and Aeronautics and Astronautics (AAE), are involved with propulsion research at Purdue. This faculty advises over 75 graduate students and postdocs in the AAE and ME departments with annual research expenditures in the $5 million/ year range. The faculty and students are supported by several staff members, including a Senior Engineer and a Technical Services Supervisor. Recently, testing and collaborative research programs have been conducted with funding from Rolls Royce Allison, Aerojet, Pratt & Whitney, Northrop Grumman Space Technologies, Precision Combustion Inc., General Kinetics, ATK, NASA Marshall Space Flight Center (MSFC), Stennis Space Center (SSC), Dryden Flight Research Center (DFRC), and Glenn Research Center (GRC), Orbital Sciences Corporation, Air Force Office of Scientific Research (AFOSR), Army Research Office (ARO), Office of Naval Research (ONR), Naval Research Office (NRO), Missile Defense Agency (MDA), Ensign-Bickford Aerospace and Defense Company (EBA&D), Defense Advanced Research Projects Agency (DARPA), and others. Liquid/ gelled, solid propellant, and airbreathing propulsion are all being studied. Additional information about the faculty and staff is available on the following Web sites: https://engineering. purdue.edu/Zucrow/People/faculty.html; https://engineering. purdue.edu/AAE/Research/ByProfessor/Propulsion; and https://engineering.purdue.edu/Zucrow/People/index.html. Liquid and Gelled Propulsion Research in liquid rocket propulsion includes studies of the ignition and chemical kinetics of hypergolic propellants; gelled propellants; development of a combined analyticalexperimental-computational testbed for combustion instability; and detailed computations of the hydrodynamics inside injector elements, rocket-based combined-cycle engines, and measurement of heat flux in a few-thousand lbf thrust multi-element oxygen-hydrogen combustor. Large-scale rocket studies are conducted on the 10,000 CPIAC Bulletin/Vol. 35, No. 3, May 2009 lbf thrust stand in the High Pressure Lab (shown in Fig. 1) during a liquid hydrocarbon film cooling test conducted for the Air Force Research Laboratory (AFRL) and its SBIR contractor, Sierra Engineering. Axially- and circumferentially-resolved heat flux measurements in a seven-element HO combustor at 1000 psia are also shown in Fig. 1; measurements like these are being used by NASA to learn how to accurately compute the 3-D reacting flowfield inside highpressure rocket combustors. A major effort to develop a methodology for a priori prediction of liquid rocket combustion instability comprises a hierarchy of analysis, experiments, and computations. Experiments using an unstable model rocket combustor are used to validate the high-fidelity (e.g., LES) computations, and those results are used to derive reduced-order combustion response models for use in engineering-level models for stability prediction. This work is being conducted for AFRL, AFOSR, and its subcontractor, INSpace. Studies to examine the combustion stability of LOX/LCH4 engines for NASA lunar missions are also underway. Most recently, Purdue was awarded a MURI from ARO for a comprehensive study of gelled propellants. The program includes the development of models for gel rheology and internal flow, as well as studies of spray formation, hypergolic ignition, and drop burning of the gelled propellant. The culmination of this program is the integration of these results into a time-accurate computational model of rocket combustor processes, ranging from flow into the injector elements to combustion product flow out the nozzle, that is validated by a benchmark experiment conducted at the Gelled Propellant Laboratory. Solid Propellants and Energetic Materials Although solid propellant studies are not new to Purdue, there has been a recent increase in solid propellant research. Currently, there are seven graduate students working in this area. With the development of propellant mixing, combustion, and characterization capabilities, researchers can now systematically develop and study new solid propellants, as well as produce standard propellants for testing. Some current projects that have been funded include a study of erosive burning (NASA); development and characterization of a new propellant binder system (MDA); high burning rate propellants (EBA&D); dynamic combustion of nano-aluminized propellants (AFOSR-STTR); development and testing of advanced propellants, including Al-ice (ALICE) propellants (AFOSR/NASA); and aluminum droplet dynamics in realistic environments (AFOSR-STTR). Related research topics on energetic materials, including nanoscale composite energetic materials, are actively pursued in laboratories in the Propulsion and Combustion Buildings. continued on page 8 Page 7 Purdue University.... University continued from page 7 Figure 2. 3-D Fan Performance CFD Analysis Conducted for a Supersonic Business Jet Flowfield (left). On the right is an image from Purdue’s compressor research facility aimed at investigating tip leakage effects on the last stage of a highly loaded Rolls-Royce outlet guide vane and pre-diffuser configuration. Airbreathing Propulsion The propulsion group at Purdue University maintains a substantial research effort in airbreathing propulsion. Purdue also maintains the nation’s only Rolls-Royce University Technology Center (UTC) in the area of high Mach propulsion. Ongoing UTC work involves the study of high temperature fuel systems and fuel coolant configurations to provide turbine cooling air for high Mach applications. Studies in coking of JP fuels, endothermic potential of JP-10, fuel/ air heat exchangers, fuel system thermoacoustic instabilities, and injection and mixing of supercritical fuels are currently underway within the UTC. In addition, a large group within the UTC is studying inlet and exhaust systems for supersonic business jet applications with Rolls-Royce and partner Gulfstream Aerospace Corp. Computational studies (Fig. 2) are being conducted on both inlet and exhaust system concepts, and advanced configurations are being studied to enhance propulsion system performance and to minimize noise. A substantial test facility (BiAnnular Nozzle Rig, or BANR) has been developed for this project to support hotfire testing of turbofan nozzle configurations. The BANR can simulate turbine and fan exit conditions to nozzle pressure ratios of 6 with overall flows of 30-50 lb/s. Experimental facilities are also available for studying turbomachinery flows. A unique high-speed rotating compressor research facility has received recent driveline upgrades, including 1400 hp motors controlled with variable frequency drives for each of the three high-speed test cells. Current research efforts are investigating flow through a high-performance Rolls-Royce centrifugal compressor assembly. A gearbox featuring a gear ratio of 30:1 provides the required 52,000 rpm shaft speed. Axial compressor research is aimed at investigating rear core performance issues, including efforts to desensitize tip leakage flows from the relatively high clearances experienced in the geometrically small stages in the rear of the core. The last stage of a Rolls-Royce comPage 8 pressor followed by a pre-diffuser and combustor plenum features a highly loaded outlet guide vane and adjustable rotor tip clearance rings. The third test cell is dedicated to investigating techniques to mitigate forced response issues in a 3-stage compressor designed by GE-Energy. Of course, the most important product of Purdue’s propulsion program is its well-educated and trained student body. Purdue is one of the few schools to offer propulsion as a major field of study and courses in airbreathing and rocket propulsion at both the undergraduate and graduate level. These unique educational opportunities provide Purdue graduates with the tools necessary for advancing the propulsion state of the art as professional engineers. Recognition of Purdue’s position and impact on the field of propulsion was evidenced last year when the University topped the Aviation Week list of preferred institutions from which the aerospace and defense industry recruits.

The mission of the DANDE is to provide an improved understanding of the satellite drag environment in the lower thermosphere at low cost. Attempting to study the Earth’s upper atmosphere is not a new endeavor, which is of great benefit to the team because leaders in the field who are located in Colorado are available to advise student efforts at the University. Project Starshine, run out of offices in Monument, Colorado, consisted of a series of passive spheres that were monitored from the ground to observe their orbits’ decay before reentry. The first sphere was launched from the Shuttle Discovery during STS-96; the next two were launched in 2001 – one during STS-108 and the other on an Athena launch vehicle. The CHAMP (CHAllenging Mini-satellite Payload) satellite, which was launched in 2000, is designed to study the gravity field of Earth and has the ability to probe the Earth’s upper atmosphere for climate modeling. The images in Fig. 1 show the radically differerent forms these satellites took on with their intended missions. Figure 2. Body frame of DANDE illustrating the rise of the drag force. show how the DANDE spacecraft identifies them. A novel accelerometer instrument is on board that rotates navigation grade accelerometers in and out of the ram vector producing a sinusoidal wave of acceleration readings. By implementing this system to register the accelerations on the satellite, the instrument is capable of submicro-g resolution. Additionally, the satellite is equipped with a Neutral Mass Spectrometer (NMS) that can register the wind on orbit along with atmospheric density. DANDE, with its dual instrument approach, is considered an active sphere and will help with the validation of the current atmospheric drag models that can vary at present by anywhere from 300 to 800%. Drag is one of the few disturbances that can affect satellites while in low Earth orbit (LEO) and becomes more prominent with the increase in atmosphere as altitude decreases. Figure 3 illustrates how the altitude of the International Space Station (ISS) fell dramatically after a solar flare hit the Earth’s atmosphere. The reason behind the solar flare Figure 1. At left, Starshine Director Gil Moore is shown holding a mockup of the Starshine 1 & 2 Payloads.1 At right, illustration of the CHAMP satellite2 while on orbit. Each of these satellites was designed with a mission to monitor one variable of the drag equation. In the case of Starshine, the parameter was atmospheric drag. CHAMP monitored the upper atmosphere, effectively providing density readings. DANDE is unique in studying the lower thermosphere for the degradation of satellite orbits because it is designed to study two important parts of the drag equation simultaneously. A basic layout of the drag equation is shown in Fig. 2, with the individual variables called out to 1 http://nasascience.nasa.gov/missions/champ 2 http://azinet.com/starshine/index.html Page 10 Figure 3. Orbit degradation of the ISS and the influence of the atmosphere. continued on page 11 CPIAC Bulletin/Vol. 35, No.3, May 2009 University of Colorado at Boulder....continued from page 10 causing a loss of altitude is due to the added energy, with the input causing there to be a lower density and expansion of the atmosphere which greatly affects satellites in LEO. DANDE intends to help define to what degree satellites can be expected to lose altitude. This type of validation is important to the U.S. Air Force since it will help them to acquire objects after a solar event. Without a valid model to map off of, the Air Force must expend significant manpower to re-track all objects. The other market for the data gathered by DANDE is in the community of LEO satellites that require a high degree of pointing accuracy. The atmospheric drag, if not acting at the center of gravity, will create a torque on the spacecraft, causing it to move away from its current position. To achieve its goals, DANDE will make measurements at altitudes between 200 and 400 km using spacecraft radar tracking and 2 on-board instruments. Tracking will be done through a collaborative agreement with the U.S. Air Force Space Command Studies and Analysis Division (AFSPC/A9A), which will provide high-priority precision tracking for drag. In order for DANDE to be operationally useful as a tracking target, it must be near-spherical, imposing challenges to the design of the structure, power, and communication subsystems. Figure 4 is an illustration of the on-orbit configuration that the DANDE is expected to have. Unique learning opportunities for student engineers are provided through these technical challenges, and excellence in engineering development is achieved as students contextualize and implement knowledge learned both in the classroom and through research activities. The DANDE project benefits students by allowing them to set requirements, design a complex system, and finally integrate and test it. DANDE provides a unique educational forum for teaching design and systems engineering, but its mission is CPIAC Bulletin/Vol. 35, No. 3, May 2009 Figure 4. Illustration of DANDE configured for on-orbit operations. also a response to government and industry needs for near-real time spaceweather and drag prediction, which are important to both government and industry operators of low-earth orbiting satellites with precision navigation needs. Additional government organizations that participate in the DANDE collaboration with CU-Boulder engineering students include the Air Force Office of Scientific Research (AFOSR), Air Force Research Laboratories (AFRL), Naval Research Lab (NRL), National Oceanographic and Atmospheric Administration (NOAA) Space Weather Prediction Center, and NASA Goddard Space Flight Center (GSFC). The DANDE project is part of the AFRL University Nanosat Program (UNP), which is aimed at the development of satellite design and research capabilities at universities as well as the education of the future space-engineering workforce (See http://www.vs.afrl. af.mil/UNP/). The UNP includes the University Nanosat Competition, likened to the national championships of satellite design. CU-Boulder’s entry in the competition was part of the fifth iteration that began with 30 university proposals 2 years ago. Those initial 30 proposals were then down-selected to a class of 10 that were funded for a 2-year design lifetime. During this time, the DANDE focused on the design of the spacecraft along with the manufacture of its flight structure. This was followed by four design reviews that were attended by members of industry and resulted in the team receiving invaluable feedback for refinement of the spacecraft. The final competion review with all of the entrants was held on January 20, 2009 in Albuquerque, New Mexico, and after a full day of demonstration and judging, DANDE was announced as the winner of the competition. Winning this competition comes with two benefits: a guaranteed launch to LEO and additional funding from the AFOSR for the final integration and testing. The satellite will be delivered by the end of the 2009 calendar year and ideally will be manifested on a launch in the 2010 to 2011 timeframe.

Session topics were: The Integrated High-Payoff Rocket Propulsion Technology (IHPRPT) program, gun propulsion, technology and manufacturing readiness levels (a specialist session), solid propellant test methods, propellant process engineering, rocket motor technologies, tactical rocket propulsion, Ares launch vehicles, scramjet technology, propulsion concepts for space exploration, solid rocket motor performance prediction, missile defense / strategic propulsion, and launch abort motor technology. 39th SMBS Technical Program SMBS conducted five sessions independently and four sessions with JPM and other subcommittees. Session topics were material properties and characterization, aging and service life, technology and manufacturing readiness levels, the business case for system health monitoring, and wireless sensors. Technology and manufacturing readiness levels (TRLs and MRLs) comprised a specialist session, which was conducted jointly by JPM, PEDCS, and SMBS. In 2008, the Department of Defense conducted a tri-service study to investigate reducing the time required to develop and qualify new tactical rocket motors. Recommendations included the establishment of descriptions of appropriate TRLs and MRLs for solid propellant rocket motors, so as to assist program planners in the early stages of development. At the workshop, various industry and government metrics of readiness levels for energetic ingredients, propellants, case materials, nozzles, thrust vector control systems, igniters, arm-fire devices, devices for insensitive munitions compliance, and other aspects of solid propellant rocket motors were considered, in order to help identify technology or manufacturing availability shortfalls that must be resolved to allow weapons development to proceed on schedule and within budget. The business case for system health monitoring was a workshop. The Air Force Research Laboratory (AFRL) is funding Consensus Technology LLC to conduct a business case study for Integrated Health Management in the chemical propulsion arena, including both solid and liquid systems. The study will require interested individuals to work with the primary investigator, James H. MacConnell, to evaluate the potential benefits of health management. Workshop participants established the evaluation process. Others interested in participating may contact Mr. MacConnell at 206-524-8555. Wireless sensors encompassed a two-day workshop. The workshop presented case studies on the use of wireless technology to transmit sensor data, including technology to detect impact on the wing leading edge of the Space Shuttle Orbiter. A panel discussion was held to consider the benefits CPIAC Bulletin/Vol. 35, No. 3, May 2009 of wireless versus wired sensor technology, the current state of the art, and obstacles to the implementation of wireless sensors. 35th PEDCS Technical Program PEDCS conducted 12 sessions independently and 10 sessions with JPM and other subcommittees. Session topics were green energetic materials, environmental protection, the status of selected propellant ingredients, propellant process engineering, technology and manufacturing readiness levels (joint specialist session – see SMBS Technical Program), solid propellant test methods, guns and high-gas-output devices, explosives formulation and development, tactical rocket propulsion, aging and service life, liquid propellants, and novel solid propellant ingredients.

A critical materials update from the 2009 meeting of The Technical Cooperation Program (TTCP) was also provided. 26th RNTS and 17th NDES Technical Program RNTS conducted three sessions independently and five sessions with either JPM or NDES. Session topics were the Integrated High-Payoff Rocket Propulsion Technology (IHPRPT) program; inspection and evaluation; rocket motor technologies; new rocket nozzle technologies; and nozzle design, test and evaluation. The sessions on inspection and evaluation were conducted jointly by NDES and RNTS. 24th SEPS Technical Program SEPS conducted three sessions independently and two sessions with PEDCS. Session topics were green energetic materials; environmental protection; toxicology; occupational and environmental health; demilitarization, reclamation and reuse technology; and hazardous material management. Subcommittee Panels The PEDCS held seven panel meetings. Variability of hydroxyl-terminated polybutadiene (HTPB) was the primary focus of the Propellant and Explosive Process Engineering Panel meeting. HTPB is a critically important solid propellant ingredient. Propellant manufacturers have encountered variations in propellant mechanical properties attributable to HTPB. In order to more effectively deal with the variability issue, the panel plans to conduct a HTPB Workshop at the JANNAF Propulsion Systems Hazards Subcommittee (PSHS) meeting in December 2009. Page 14 Of particular interest to the Solid Propellant Ingredients and Formulations Panel are foreign developments in energetic materials and energetics databases administered by the Department of Energy (DoE). The panel also plans to work with the Propellant and Explosive Process Engineering Panel in conducting a future HTPB workshop. The Chemical Test Methods Panel decided to review the methods in the CPIA Propellant Characterization Handbook (CPIA Publication 507) to determine whether they are still appropriate and represent the state of the art. The panel also reviewed recent progress in the addition of spectral data to CPIAC’s Propellant and Explosive Ingredients Database. Members of the Guns and High Gas Output Devices Panel meeting discussed the findings of a recent workshop on sub-scale insensitive munitions testing conducted under The Technical Cooperation Program (TTCP). The panel also decided to plan for a workshop on closed bomb testing to be conducted in conjunction with the 2010 TTCP meeting. Items of interest expressed at the Surveillance and Aging Panel meeting were a workshop on test methods for propellant aging, a workshop on relations between propellant chemical and mechanical properties as they are affected by aging, application of wireless sensor technology to surveillance, and collaboration with the Joint Propellant Safety and Surveillance Board. Attendees at the Liquid Propellants Panel meeting were interested in the continued need for material compatibility studies, ground support equipment requirements for hypergolic bipropellants, quantity-distance criteria for liquid propellants, the status of military specifications for hypergols, and a study in the variability of RP-1 hydrocarbon fuel. The Energetic Materials Development Panel focused on following the development of specifications for CL-20 and NTO. It was also suggested that panel members look at CPIAC’s online Propellant & Explo- sive Ingredients Database (PEID) and provide input to CPIAC regarding any new ingredients that should be added. Two RNTS panels held meetings. Discussion topics of the Nozzle Design and Evaluation Panel included replacement of North American Rayon Corporation (NARC) rayon for the Reusable Solid Rocket Motor nozzle, the nozzle erosion Multidisciplinary University Research Initiative (MURI) program funded by the Office of Naval Research, the need to document char and erosion kinetics to maintain the knowledge base and archive lessons learned, and possible paths for funding nozzle material research and testing. Topics of interest to the Rocket Nozzle Modeling Panel were thermo-structural modeling of tape-wrapped composite parts, combined aerothermal/gas-dynamic analyses of nozzle components, and two-phase combustion gas interaction with nozzle materials. The SEPS held four panel meetings, including a combined meeting of the Instrumentation Panel and the Range Safety and Atmospheric Modeling Panel. They considered various ideas for facilitating the updating of CPIA Publication 394 (Hazards of Chemical Rockets and Propellants). Topics of interest to the Occupational Health and Toxicology Panel were contribution to and review of the proposed Green Energetic Materials Handbook (more on this in the next paragraph), contribution to ASTM methods for evaluating toxicity, participation in the ASTM nanomaterials group, coordination of nanomaterial environmental/safety/health issues within the JANNAF community, and contribution to the tri-service Toxicology and Risk Assessment Conference (TRAC). Attendees at the Demilitarization, Reclamation, and Reuse Technology Panel meeting expressed interest in the comparative economics of ammonium perchlorate conversion to perchloric acid versus chlorate salts, continued on page 16 CPIAC Bulletin/Vol. 35, No.3, May 2009 JANNAF Members Enjoy Conference and Reception CPIAC Bulletin/Vol. 35, No. 3, May 2009 Page 15 JANNAF Propulsion Meeting and Joint Subcommittee Meeting....continued from page 14 recovery of nitroguanidine from triple-base propellants, and reuse of nitrocellulose from SPD 16-in. gun propellant. Panel meetings included the Green Energetic Materials and Environmental Protection Panel, which is governed jointly by PEDCS and SEPS. One of the tasks discussed by the panel is the development of a green energetic materials handbook that outlines the history of green energetics, lessons learned, and regulatory applicability. This task may lead to a procurement manager’s guide to green energetics as well. Another possible task is the development of a guide to environmental tests needed in the course of implementing new energetic materials. The guide could include a flow chart showing the optimal progression of testing and a model time line to indicate which tests are needed and when. Panel members also shared information as to the best sources of environmental property data. Four SMBS panels also held meetings. The Structural Analysis Panel is considering revision of CPIA Publication 612, which is a handbook of guidelines for determining rocket motor grain design margins of safety. The Defect Evaluation Panel has completed round-robin tests for propellant defect and analog wedge fracture analyses. They also prepared a Solid Rocket Motor Defect Summary Chart to supplement a defect detection capabilities document developed by NDES. The Materials Properties and Characterization Panel is looking to update CPIA Publication 21 (Solid Propellant Mechanical Behavior Manual) with new and revised testing procedures. The panel members would also like to create a digital version of the document and to verify that the procedures comply with NATO STANAG re- quirements. The Service Life Panel has cosponsored two workshops on missile system health monitoring. Additional tasks comprise formation of a users’ group for Texchem (a computer program that models diffusion effects within complex structures), development of guidelines for the use of sensors in monitoring service life, and a joint workshop with PEDCS on material properties that need to be measured for service life characterization. Although the Modeling and Simulation Subcommittee (MSS) did not have a full meeting at this time, its Solid Rocket Motor Performance Prediction and Standardization Panel met. The panel decided to collect BATES motor firing data conducted at AFRL as well as test data from the Tullahoma range, to create a database for comparison with predictions. The panel also agreed upon physical phenomena that need to be better understood and modeled to improve prediction. The next step is to identify specific models and down-select for validation.

While ATK’s motor firing took place at the ATK Space Systems, T-6 Test Facility in Promontory, Utah, Aerojet conducted its test at the Air Force Research Laboratory, Edwards AFB, Calif. AFRL oversees the IHPRPT program, with participation from industry, to advance technologies and materials to meet the goals established for increased motor performance and improved mass fraction, while reducing cost. ATK and the AFRL successfully tested a developmental solid rocket motor, designated Phase II, on December 12, 2008, culminating an eight-year development and production effort. The data and technology from this test will help develop even more robust solid rocket motors with high energy propellants, lighter components (including next-generation cases and nozzles), and lower production costs. Reduced weight and increased motor energy are key factors to increasing rocket motor performance. Incorporated in the Phase II motor was a higher performance composite case, low-cost improved insulation material, a unique trap-ball nozzle joint, and upgraded material on the liner of the nozzle’s exit cone. The Phase II motor contained more than 2,000 lbs of high-energy propellant that was packaged in a 37-in.-dia. composite case and produced more than 19,900 lbf throughout the approximate 30-sec duration of the test. Just a few months later on March 11, 2009, Aerojet and the AFRL successfully conducted, at simulated altitude conditions, a static test of Aerojet’s Technology Assessment Motor (TAM) in support of the IHPRPT Phase II program. Aerojet’s TAM design incorporates numerous advanced technologies and materials to demonstrate achievement of the Phase II performance goals for solid propulsion rocket motors to include increasing motor performance by 4 percent and improving mass fraction by 25% while at the same time providing a 25% reduction in hardware and operational and support costs. In order to meet these goals, Aerojet’s TAM configuration uses new technologies, materials and fabrication processes, including 6,380 lbm of high-energy solid propellant loaded in a composite case that uses environmentally benign resin and a supersonic splitline flexseal nozzle (SSFN) with a domestically produced Triaxially-Braided C/C Exit Cone. Orbital Sciences Corporation integrated a new modular electrical-mechanical thrust vector control actuation (EM TVA) system by using Moog-supplied EM actuators and a digital controller. The unique SSFN represented the highest payoff component to be evaluated because it enabled increased motor performance and mass fraction as well as enhanced Thrust Vector Control (TVC) capability for upper stage strategic propulsion systems. It was the first full-scale, long-duration, altitude static test of this technology as part of the IHPRPT program. During the 42-sec static firing, the 46-in.-dia. TAM achieved a peak thrust of more than 48,000 lbf. Initial post-test inspection indicated that all components, including the supersonic Courtesy of ATK Editor’s Note: The initial publication of this article on May 5, 2009 contained inaccurate statements, which have been corrected in the version published below.

Technologies that are developed from the IHPRPT program can be transferred to other motor programs that currently exist or develop in the future. Developments from an IHPRPT Phase I motor that ATK and AFRL successfully tested eight years ago have been incorporated in both strategic and commercial solid rocket motor programs.

Page 19 Spotlight on SBIRs/SBTTs Maryland Company Develops Optimization Tool to Generate Reduced-order Kinetics Models for Scramjet Applications By P. Gokulakrishnan, D. S. Viehe, M. S. Klassen, and R. J. Roby Combustion Science & Engineering, Inc., Columbia, Maryland Combustion Science & Engineering (CSE), Inc. is an engineering consulting and research and development company that specializes in a range of combustion and fire related areas including CFD modeling of turbo machinery components, reactive flow simulation of combustors, and fire protection. CSE also has experimental facilities for small and large scale combustion and fire experiments. CSE has been working on several projects funded by the U.S. Department of Defense for the U.S. Air Force. The current work was supported by a Small Business Technology Transfer (STTR) from the Office of the Secretary of Defense to develop a kinetics modeling tool for the reactive flow simulation of scramjets using hydrocarbon fuels. Dr. Dan Risha of the U.S. Air Force Research Laboratory (AFRL) was the program manager of this project. CSE collaborated with Professor Suresh Menon of Georgia Tech and Professor Robert Pitz of Vanderbilt University on this work. As part of this project, CSE has conducted laboratory scale kinetics experiments to measure the ignition delay time of jet fuels such as JP-7, JP-8, and synthetic jet fuel, S-8. These experimental data were used to validate the detailed surrogate kinetics mechanism for kerosene-type jet fuel, which was also developed by CSE (Gokulakrishnan et al., 2007). The detailed kinetics mechanism was used to generate ignition delay time data necessary for the optimization of reduced-order kinetics models developed in the current work. Professor Menon developed a scramjet test facility at Georgia Tech to perform flameholding experiments at Mach 2.5. Professor Pitz developed Raman diagnostics techniques for species measurements in high speed flows at the scramjet test facility. These experimental data are useful for the model validation of the reactive flow simulation of scramjets. Currently, hydrogen-fueled propulsion, because of its rapid burning and high mass-specific energy, is preferred for hypersonic air-breathing engines with flight Mach numbers of 10 or greater. Liquid hydrocarbon fuels become viable alternatives to hydrogen at Mach numbers below 10, and are desirable because of their greater fuel densities and endothermic cooling capabilities. However, liquid hydrocarbon fuels pose an inherent difficulty for flame holding under high speed supersonic flows due to their long ignition delay times and shorter stability window for blow-out relative to hydrogen. Thus, one of the difficulties in the reactive flow simulation of scramjets is the development of a reduced order kinetics model which is capable of predicting the non-equilibrium, transient kinetics processes ,such as ignition and blow-out. As part of this project, CSE has developed optimization software, known as the Page 20 reduced kinetics model generator (rkmGen), for reaction rate parameter estimation and optimization of reduced order kinetics models for scramjet applications. The optimization procedure uses the ignition delay time as the target data to estimate the reaction rate parameters of a given reaction. This modeling tool can be used to generate reduced kinetics mechanisms of different sizes (and hence different utility and accuracy) by calibrating against ignition delay time data for a given fuel. The rkmGen can also be used to optimize the reduced kinetics mechanism over a wide range of temperatures, pressures, and equivalence ratios. A stochastic optimization algorithm known as the Simulated Annealing was implemented in C++ and coupled with Cantera, a chemical kinetics software, to automate the reduced kinetics mechanism generation process. The oxidation of hydrocarbon fuels such as kerosene involve thousands of reactions and hundreds of species that would constitute a ‘detailed’ kinetics model. However, coupling of a large detailed kinetics model with transport equations to solve for heat, mass, and momentum is computationally expensive for CFD simulation of practical devices. The bulk of the computational time is spent on resolving the source term of the species that is defined by a set of stiff ODEs. Therefore, using a reduced order kinetics model will drastically reduce the simulation time. However, the utility of the reduced order model will be limited relative to a detailed kinetics model. The optimization software developed in this STTR can be used to tune reaction rate parameters so that the reduced order model will have high fidelity during CFD simulation. For example, a two-step kerosene reduced kinetics model can be given by: C11H22 + 11 O2 => 11 CO + 11 H2O (1) CO + 0.5 O2 = CO2 (2) The reaction rate parameters for reaction (1) were estimated using rkmGen by performing optimization over 1000K to 2400K temperature range and 0.1atm to 10atm pressure range. Figure 1 shows the model predictions of a two-step, kerosene reduced kinetics model predictions for ignition delay time compared with target data generated from a detailed kerosene mechanism. As can be seen in Fig. 1, a two-step reduced kinetics model is sufficient to predict stable flame properties. However, for CFD simulation of transient processes, such as flame blow-out, additional reaction steps are needed. For this purpose, CSE developed and implemented a slightly larger reaction scheme continued on page 21 CPIAC Bulletin/Vol. 35, No.3, May 2009 Figure 1.

In a simplification of the actual process, the fuel decomposition steps can be modeled as a single reaction via: C2H4 + O2 => 2 CH2O (3) Formaldehyde is one of the intermediates of hydrocarbon oxidation. The subsequent formaldehyde oxidation was modeled with a detailed reaction scheme. The reaction rate parameters for reaction (3) can be estimated from rkmGen for given conditions. The ethylene reduced order kinetics model that has 14 species and 44 reactions was implemented in a commercial CFD code to simulate the cavity flameholder experimental conditions of Rasmussen et al.

For many years, parts of America’s space industry have complained that the rules governing the export of technology are too strict, resulting in rules that favor “lumbering dinosaurs such as Lockheed Martin and Boeing...rather than nimble but small ‘furry mammals’ that need every customer they can get.” Bigelow Aerospace, which is trying to develop inflatable space hotels, filed a challenge to these rules in 2007 because it “disputed the government’s claim that foreign passengers travelling on a spaceship or space station were involved in a transfer of technology.” The courts ruled in favor of Bigelow’s position in February. Robert Dickman, executive director of the AIAA, says the decision appears to convey a new willingness to “move away from the very restrictive approach that has been in place for almost a decade.” Full press release: http://www.economist.com/science/tm/displaystory.cfm?story_id=13525115 These excerpts have been taken from press releases approved for public release and reprinted with permission.

A diverse crowd of 184 people attended the first NCRES held on 27-28 April, at the College of Southern Maryland in La Plata. Attendance represented 16 government organizations, 4 universities, and 10 industry partners. The NCRES was co-hosted by the Indian Head Division, Naval Surface Warfare Center (IHDIV) along with the Energetics Technology Center and the University of Maryland Center for Energetic Concepts Development. During the two day symposium, attendees heard over 40 presentations, with keynote addresses given by RADM Millard Firebaugh, USN (ret.), VADM Ronald Route, USN (ret.), and Mr. Stephen Mitchell, the Technical Director of the Naval Surface Warfare Center. In his keynote address, Rear Admiral Firebaugh challenged the community to develop energetics developed specifically for unmanned vehicles. During this address he asked the energetics community to work together with the warfighters to "imagine new capabilities and try to discover how the science can serve those imaginings." Presentations during the symposium addressed topics such as insensitive munitions, weaponizing unmanned vehicles, and new energetic materials for weapons systems. Presentations were given by researchers from IHDIV, Army Research Laboratory (ARL), Armament Research Development and Engineering Center (ARDEC), the IHDIV (Earle Detachment) Packaging Handling Shipping Transportation Center, Univ. of Maryland, Penn. State University, New Jersey Institute of Technology, and the Ludwig-Maximilians University of Munich (Germany). During the event, Penn. State professor Dr. Kenneth Kuo was presented with a lifetime achievement award by NSWC Technical Director Stephen Mitchell. Dr. Kuo was recognized for his achievements in developing energetic materials for gun propellants, and mentoring over 100 student researchers in the energetics field during his career. IHDIV develops, researches, produces, tests, and evaluates a wide variety of DoD systems operating on land, air and sea. IHDIV's largest area of expertise is the field of energetic materials, which are in use in items from torpedoes to rockets to ejection seats. The Professional Development Council (PDC) is a team of non-management individuals from IHDIV. They serve a term of nine months in which many aspects of their professional and personal lives are enriched. This is accomplished through leadership exercises, community service, a corporate project, social events, shadowing management activities and much more. This year the PDC’s corporate project was to hold a National Capital Region Energetics Symposium. The event was a huge success and was a great learning experience for these young professionals.
