Certification and Operating Clearances: Mr. Lillesand holds a Level 3 HPR certification. Dr. Pinkas has a Level 1 HPR certification and plans on having a Level 2 HPR certification by the end of February 2012. Mr. Havlena holds a level 1 HPR certification. He plans to complete his Level 2 by April 2012 and is our back-up launch supervisor. Mr. Lillesand has Low Explosives User Permit (LEUP). If necessary, the team can store propellant with Mr. Goebel, who owns a BATFE approved magazine for storage of solid motor grains containing over 62.5 grams of propellant. Mr. Lillesand is the designated individual rocket owner for liability purposes and he will accompany the team to Huntsville. Upon their successful L2 certification, Mr. Havlena and Dr. Pinkas will become a backup mentors for this role. All HPR flights will be conducted only at launches covered by an HPR waiver (mostly the WOOSH/NAR Section #558 10,000ft waiver for Richard Bong Recreation Area launch site). All LMR flights will be conducted only at the launches with the FAA notification phoned in at least 24 hours prior to the launch. NAR and NFPA Safety Codes for model rockets and high power rockets will be observed at all launches. Mentors will be present at all launches to supervise the proceedings. b. Motors: We will purchase and use in our vehicle only NAR-certified rocket motors and will do so through our NAR mentors. Mentors will handle all motors and ejection charges. c. Construction of Rocket: In the construction of our vehicle, we will use only proven, reliable materials made by well established manufacturers, under the supervision of our NAR mentors. We will comply with all NAR standards regarding the materials and construction methods. Reliable, verified methods of recovery will be exercised during the retrieval of our vehicle. Motors will be used that fall within the NAR HPR Level 2 power limits as well as the restrictions outlined by the SLI program. Lightweight materials such as fiberglass tubing and carbon fiber will be used in the construction of the rocket to ensure that the vehicle is under the engine’s maximum liftoff weight. The computer program RockSim will be utilized to help design and pre-test the stability of our rocket so that no unexpected and potentially dangerous problems with the vehicle occur. Scale model of the rocket will be built and flown to prove the rocket stability. d. Payload: As our payload does not contain hazardous materials, it does not present danger to the environment. However, our NAR mentors will check the payload prior to -14- Madison West High School New Team SLI 2012 SOW launch in order to verify that there will be no problems. e. Launch Conditions: Test launches will be performed at Richard I. Bong Recreation Area with our mentors present to oversee all proceedings. All launches will be carried out in accordance with FAA, NFPA and NAR safety regulations regarding model and HPR rocket safety, launch angles, and weather conditions. Caution will be exercised by all team members when recovering the vehicle components after flight. No rocket will be launched under conditions of limited visibility, low cloud cover, winds over 20mph or increased fire hazards (drought). II. Hazardous Materials All hazardous materials will be purchased, handled, used, and stored by our NAR mentors. The use of hazardous chemicals in the construction of the rocket, such as epoxy resin, will be carefully supervised by our NAR mentors. When handling such materials, we will make sure to carefully scrutinize and use all MSDS sheets and necessary protection (gloves, goggles, proper ventilation etc.). All MSDS sheets and federal/state/local regulation applicable to our project are available online at http://westrocketry.com/sli2012/safety/safety2012n.php III. Compliance with Laws and Environmental Regulations All team members and mentors will conduct themselves responsibly and construct the vehicle and payload with regard to all applicable laws and environmental regulations. We will make sure to minimize the effects of the launch process on the environment. All recoverable waste will be disposed properly. We will spare no efforts when recovering the parts of the rocket that drifted away. Properly inspected, filled and primed fire extinguishers will be on hand at the launch site. Cognizance of federal, state, and local laws regarding unmanned rocket launches and motor handling The team is cognizant and will abide with the following federal, state and local laws regarding unmanned rocket launches and motor handling: Use of airspace: Federal Aviation Regulations 14 CFR, Subchapter F, Part 101, Subpart C Handling and use of low explosives: Code of Federal Regulation Part 55 Fire Prevention: NFPA1127 Code for High Power Rocket Motors All of the publications mentioned above are available to the team members and mentors via links to the online versions of the documents. -15- Madison West High School New Team SLI 2012 SOW http://westrocketry.com/sli2012/safety/safety2012n.php WRITTEN STATEMENT OF SAFETY REGULATIONS COMPLIANCE All team members understand and will abide by the following safety regulations: a. Range safety inspections of each rocket before it is flown. Each team shall comply with the determination of the safety inspection. b. The Range Safety Officer has the final say on all rocket safety issues. Therefore, the Range Safety Officer has the right to deny the launch of any rocket for safety reasons. c. Any team that does not comply with the safety requirements will not be allowed to launch their rocket. IV. Education, Safety Briefings and Supervision Mentors and experienced rocketry team members will take time to teach new members the basics of rocket safety.

We will be observing the effects of gravitational forces and vibration on diffusion in liquids. The project code name of the vehicle is Hydros. The rocket will be constructed from LOC Precision fiber tubing, using balsa/G10 sandwich for fins. The rocket will be robust enough to endure 20+g of acceleration and high power rocket flight and deployment stresses. To have a successful mission the rocket must reach (but not exceed) altitude of one mile AGL and the payload must record all data necessary for our experiment. The rocket will be 108 inches long, with a 5.5 inch diameter for payload and recovery system sections, 4 inch diameter for the booster and fin assembly. It has estimated liftoff mass of 9 kilograms. The proposed vehicle and propulsion options are discussed in detail below. The primary propulsion choice is a K-class motor with total impulse of 2522 Ns. The vehicle can launch from a standard size, 8ft launch rail. The rocket will use dual deployment to minimize drift.

The vehicle reaches the apogee of 5207ft seventeen seconds (17s) after the ignition. For the purpose of this preliminary simulation the coefficient of drag is set to CD = 0.5 (we have flown this type of vehicle during our two prior SLI projects and all our experimental data indicate that CD = 0.5 is the correct estimate of overall drag coefficient for a boat-tailed vehicle). Figure 3: Altitude vs. time graph for AT K1050W motor. The rocket reaches 5207ft at 17s after ignition. Wind Speed vs. Altitude The effect of the wind speed on the apogee of the entire flight is investigated in the table below. Even under the worst possible conditions (wind speeds of 20mph, the NAR limit) the flight apogee will differ by less than 3% from the apogee reached in windless conditions. Wind Speed [mph] 0 5 10 15 20 Altitude [ft] 5207 5199 5173 5128 5065 Percent Change in Altitude 0.00% 0.10% 0.40% 1.60% 2.80% Table 10: Flight apogee vs. wind speed -21- Madison West High School New Team SLI 2012 SOW Thrust Profile The graph below shows the thrust profile for the K1050W motor. The K1050W motor quickly reaches its maximum thrust of 1200Ns and remains at this thrust level for about 2s (the average thrust-to-weight ratio is 12.4). The rocket requires a standard eight-foot rail for sufficient stability on the pad and leaves the 8ft rail at about 55mph. Figure 4: Thrust vs. time graph. The motor delivers maximum thrust of just over 1200 N and burns for 2.3s. Velocity Profile According to the velocity profile (next graph), the rocket will reach maximum velocity of 540mph shortly before the burnout (2.3s). The rocket remains subsonic for the entire duration of its flight. Figure 5: Velocity vs. time graph. The motor burns out at 2.3s and the rocket reaches its maximum velocity of 540mph shortly before burnout. The rocket remains at subsonic speed range for entire duration of its flight. -22- Madison West High School New Team SLI 2012 SOW Acceleration Profile The graph below shows that the rocket will experience maximum acceleration of about 15g. Our rocket will be robust enough to endure the 20g+ acceleration shocks. Figure 6: Acceleration [g] vs. time [s] graph. The rocket experiences maximum acceleration of approximately 15g.

Two fully independent PerfectFlite MAWD altimeters will be used to fire the ejection charges. Each altimeter will have its own power source, external arming switch and set of charges. The drogue charges will be fired at apogee (5,280ft). The main parachute will be deployed as field conditions require to prevent excessive drift, most likely at 700ft or 900ft. The table below shows the estimated parachute sizes, descent rates and landing impact energy. As required, the rocket separates in no more than four tethered/independent sections (three (3) sections in our case) and the impact energy is no more than 75 ft-lbf for any of the parts (the impact energy for the entire rocket is 74.6 ft-lbf).

Beginning with 2011/2012 school year, system Hermes will be used in all Madison West Rocketry sounding rockets. The system has been flight-tested during Rockets For Schools 2011 launch. System Hermes provides the following functionality out-of-box: Altitude and 3D acceleration data (100Hz, 8x oversampling, 12 or 16bit) Flight phases analysis (detects takeoff, burnout, staging, apogee, landing) Full duplex serial communication between rocket and ground (900MHz XBee) 96KB of built-in memory for experimental data (expandable as needed) GPS location (transmitted to the ground station over wireless link) Telemetry link (for experimental data transmissions) Extension ports for payload controllers or other devices Regulated DC voltage to power other components (+5V, +3.3V) In this season we intent to use the Hermes system to replace the custom developed PCB boards to speed-up the payload development and to improve our tracking and recovery. The system will not be used for deployment purposes this year (we will continue to rely on proven PerfectFlite MAWD altimeters). -26- Madison West High School New Team SLI 2012 SOW Performance Targets that Apply to Vehicle The following performance targets apply to the vehicle.

A soluble dye will be used to track the movements of liquid during rocket flight. High definition video-camera (1920x1080 pixels at 30 or 60 fps will record movements of the dye front and changes in dye distribution). After the flight the standard image analysis methods will be applied to quantify the visual observations. Figure 8: Proof of concept experiment. The leftmost picture shows stationary undisturbed liquid with tracking dye. On the center picture the liquid is subjected to vibrations and changes in dye distribution become apparent. The rightmost picture shows the dye distribution after the vibrations have ceased. We have carried out several preliminary experiments using Royal Blue food coloring dye (soluble in water). Selected results of our preliminary experiments our shown on the picture above. We have found that the addition of the dye into solution allows us to easily track effects of vibrations on the body of the liquid. We have observed both local increases and decreases in dye concentration, including complete displacement of the dye by clear liquid at certain spots. From engineering point of view, existence of non-uniform concentration profiles in liquid or gaseous reaction systems/mixtures can lead to creation of hot/cold reaction regions, both of which can present problems and dangers. For example an exothermic reaction that is under control in perfectly mixed system can create hot spots and go into a thermal runaway if severe concentration gradients are created by vibrations of the reaction vessel. Or, a crucial reaction can suddenly terminate if the reactants are not well mixed and in sufficient contact with each other. Just a few years ago this kind of experiment was out of our reach because small videorecording devices with necessary resolution and recording capacity were outside our budget or nonexistent. Minimum focus distance of cameras was another problem as the space inside the rocket is very limited. Thanks to the rapid advances of photo and video industry, today we can easily afford a high definition video camera with a lens that will -28- Madison West High School New Team SLI 2012 SOW focus down to 1cm and will record more than 1 hour of high definition video before running out of memory/battery. Our preliminary design and calculations show that we will be able to observe diffusion patterns in a liquid system using a 5.5" diameter vehicle. Experimental Setup A basic functional of our payload is shown on the figure bellow. The liquid is housed in a fully enclosed, leak-proof vessels made out of polycarbonate. The entire body of the liquid is evenly illuminated using white LEDs powered from on-board batteries. The dye injector is activated when the on-board avionics senses rocket liftoff (a servo will drive a plunger thus forcing the liquid dye out of its container into the clear liquid). High definition video camera will record movement of the dye in the liquid during the flight. At this moment we are considering Panasonic Lumix TS3 camera as the primary candidate for video-recording - the camera is capable of focusing down to 1cm and is also waterproof (aiding the survival of recorded data should the liquid container break during flight). The liquid payload in the setup shown below is positioned horizontally (perpendicular to the flight trajectory) and we expect that this payload configuration will mostly record the effects of vehicle vibrations on the dye distribution. Figure 9: Payload functional unit - liquid is in enclosed transparent vessel illuminated by white LED lights. The dye is injected instantly when the rocket avionics senses lift-off. Camera will record movement of the dye during rocket flight. -29- Madison West High School New Team SLI 2012 SOW The close focus capability of Lumix TS3 camera (and similar cameras) allows us to also use a vertical experimental setup where the dye is injected at either top or bottom end and the camera record the dye diffusion. An example from our preliminary experiment with vertical experimental setup is shown on the following picture. Figure 10: Preliminary experiment with vertical setup: the dye was injected at the top of the liquid body and pictures of the system were taken every 0.3s. The liquid dye has a higher density than the clear liquid (water) and thus in our labbench experiment the dye droplet moved from the top to the bottom of the vessel, leaving a diffusing trail of dye. During the rocket flight a lot higher gravitational force will apply during boost (estimated acceleration is 12g) followed by negative acceleration and a short period of sub 1g gravity. We plan to have two vertical setups in the rocket (one camera will suffice to record both vertical setups) and inject the dye from the top in one of the setups and from the bottom end in the other setup. With the vertical setups we expect to observe primarily the effects of gravitational forces even though the rocket vibration will affect the dye diffusion as well. The vertical setup is shown on the drawing below. Figure 11: Vertical setup - the same camera is watching two vessels with the liquid. The dye is injected from the top of one of the two vessels and from the bottom of the other vessel. -30- Madison West High School New Team SLI 2012 SOW Universal Avionics Platform - System Hermes As mentioned in the Vehicle section of this document, our payload will be aided by universal avionics platform, system Hermes. We will develop a simple payload controller to interface with Hermes system. Our payload controller will receive liftoff signal from Hermes and activate the servos driving the dye injectors and cameras. Upon receiving the apogee signal, the payload controller will terminate recording. Altitude and acceleration will be recorded by system Hermes itself and the liftoff/apogee signal transmission will be marked for later alignment with data recorded by the cameras. Experimental Sequence 1. As the rocket lifts off, the G-force sensor senses the gravitational forces and triggers the ejection of the blue dye into the liquid solutions, and the camera starts to take pictures of the diffusion. 2. During flight, the dye diffuses in the liquid and the video-camera records the dye diffusion. 3. Once the rocket reaches 700ft. while descending, the main parachute deploys and the rocket lands softly. 4. The image data will be downloaded from cameras and analyzed as described in the Data Analysis section. 5. The results will be reported in Post Launch Assessment Report. -31- Madison West High School New Team SLI 2012 SOW We plan to observe the dye diffusion in three different phases of the rocket flight: high-g phase, negative-g phase and low gravity phase. The first phase starts at ignition and the last phase ends at apogee. The graph below shows the phases (note: for brevity the graph is cut off at 10s, however the apogee does not occur until 17s). An on-board accelerometer will record acceleration on all three axes. Figure 12: Flight phase: red - boost, high-g phase, blue - shortly after burnout, negative-g phase, yellow - coast until apogee, low gravity phase. -32- Madison West High School New Team SLI 2012 SOW Data Analysis Identical experimental setups will be placed in the rocket and on the ground. The ground setup will provide the baseline measurements (diffusion without flight-induced gravitational forces and vibrations). The data from both the ground setup and the onboard setup will be compared, the following variables will be measured and correlation constructed: Independent variables a t Acceleration Time after dye is released (flight time) Dependent Variables R P Rate of diffusion (diffusion front speed) Pattern of diffusion (qualitative classification) Correlations R = f(a) R = f(t) P = f(a) P = f(t) Rate of diffusion in relation to acceleration Rate of diffusion in relation to time after dye is released Pattern of diffusion in relation to acceleration Pattern of diffusion in relation to time after dye is released Constants Temperature inside of rocket Amount of dye injected Color saturation of dye Volume of liquid in container Hypotheses We make the following hypotheses: 1) We expect that the vibrations of the rocket will affect strongly the horizontal diffusion rate (horizontal = perpendicular to the flight trajectory). 2) We expect that the gravitational forces (acceleration/deceleration) will strongly affect the vertical diffusion rate. 3) We expect that there will be significant different between diffusion rates observed in on-board setups as opposed to the reference setups residing on the ground. -33- Madison West High School New Team SLI 2012 SOW Post Flight Procedure After a successful flight and rocket/payload recovery, we will download the data recorded by the cameras to a computer. The data will be analyzed as described in Data Analysis Section and the final report (PLAR) will be compiled and submitted to NASA. -34- Madison West High School New Team SLI 2012 SOW Performance Targets The performance targets for the reusable launch vehicle and payload are as follows: 1.

Booster section alignment: The rocket has a transition from 5.5" payload section to 4" booster section. An utmost precision during construction is necessary to prevent misalignment of the booster tube. We will user laser beams to align the tubes and dry fit entire assembly before applying the epoxy glue. Post-assembly measurement will be used to prove the success. 2. Large, heavy rocket: We know from our previous experiments with this type of vehicle that we will need a full K motor to deliver this rocket to one mile. Precise construction, including pursuit of all weight saving opportunities will be necessary. The rocket will be equipped with a conical motor retainer and finished with glossy paint to decrease the drag coefficient even further. 3. Heavy loads on anchors: successful construction and operation of a 5.5" vehicle is a drastically different task from the more traditional and manageable 4" vehicle. Special attention needs to be paid to all anchor points, coupler stiffeners and positive lock-in must be used on all load-bearing parts. 4. Coupling surfaces: coupling of 5.5" tubing is generally unforgiving to minor issues that would present no problem with 4" tubing. We will pay attention to perfect alignment and cleanliness of our coupling surfaces, using talcum powder to lubricate all separation points. Major Payload Challenges and Solutions 1. Liquid payload: possibility of leaks and high density (weight) of payload need to be addressed during design. We will build our own reaction vessels and test them for leaks. The outer payload compartment will be sealed from the rest of the vehicle to prevent liquid leakage in case of payload damage. Payload electronics will not have any active role in rocket flight and will be in a different e-bay altogether. 2. Dye injection: we are facing the problem of building sufficiently fast and leakproof dye injector. The injector must not introduce air bubbles into the system, permit leaks or sloshing and must function under high acceleration (during rocket liftoff). We are currently considering a system consisting of short throw servos and a piston. -43- Madison West High School New Team SLI 2012 SOW 3. Timely payload activation: the colored dye needs to be injected into clear liquid as soon as the rocket starts moving. We will use short throw servos to execute the injection and finely tuned G-switch triggers to detect the liftoff. 4. False liftoff detection: maximizing the sensitivity of G-switch triggers for payload activation brings the problem of false positives in liftoff detection. To mitigate this issue we will only activate the G-switch triggers after the rocket has been placed on the pad and all personnel has retreated back. The Gswitch triggers will be activated remotely via wireless link. The payload will also use the wireless link to report the liftoff detection so we have an indication of false trigger condition and can reset the payload. Lastly, redundant diffusion vessels will be prepared prior to the launch to quickly replace the falsely triggered vessels (should such mishap occur). 5. Data analysis: high definition video present serious challenge in data processing because of the size of collected information. We will use high performance Linux quad core computers for final image analysis. 6. Extensive preliminary lab work: While we have successfully carried out proof-of-concept experiments, much work remains before the payload can be finalized. We will need to optimize dye selection with respect to observed diffusion rates. We have already started experiments with more viscous liquids (such as corn syrup) should the need to slow down the diffusion rates arise. -44- Madison West High School New Team SLI 2012 SOW Educational Engagement Community Support After eight years of the club’s existence, we are well known at various departments of the UW and many researchers are eager to work with us. During our seven years of participation in SLI we have met with a number of people from various departments within the University of Wisconsin-Madison, including Professor McCammon from the department of Physics, Professor Eloranta from the department of Atmospheric Sciences, Professor Pawley from the department of Zoology, and Professors Anderson and Bonazza from the department of Mechanical Engineering. Last year we have added Prof. Fernandez and Prof. Gilroy from the department of Botany, and Prof. Masson from the department of genetics.These contacts have been incredibly helpful in designing and refining our original experimental ideas and creating an experiment that will return meaningful data. We have finally achieved official affiliation with UW Madison and our research meetings are now held in Chamberlin Hall, Dept. of Physics. Every year we raise funds by raking leaves during autumn in local neighborhoods. We find this is an excellent way to earn the support of the community and increase our visibility. The club also provides a steady stream of volunteers for public television and public radio fundraising drives. While this is not a direct display of our work or interests, it gives us the opportunity to provide public service in the name of our club. In 2009 many club members gave back to the community by helping build a fence in the local soccer park where we also happen to launch our TARC practice flights in the winter. We are currently discussing other soccer park improvements with their management. -45- Madison West High School New Team SLI 2012 SOW Outreach Programs Last year we participated in many educational engagement opportunities, such as helping sizeable groups of young children at the local middle schools to build and fly Alka-Seltzer powered rockets. We launched about 300 rockets for an audience of about 150 kids during this program, as well as displaying some of our TARC, SLI and R4S rockets. We will also be participating in our annual “Raking for Rockets” program, where we rake community lawns in order to simultaneously bring about an increased awareness in rocketry, and raise the funds necessary for our TARC and SLI programs. Besides these programs, we also recruited new members for our club at Madison West High School (our current membership is above 50 students mark) in a number of recruitment events which included the daily announcements, organized recruitment events , and posters throughout the school advertizing the location and time of the first informational meeting. The new members will participate in TARC, along with a few returning members from our SLI teams. TARC club meetings have already started for this school year, with interested new members learning about the basics of rocket design, building, and operation. The table below show the outreach programs that plan for this year. The programs target primarily elementary and middle schools.

-53- Madison West High School New Team SLI 2012 SOW Sustainability The rocketry program at Madison West High School is now in its ninth year, and it provides a strong, compelling incentive for students to research unique science concepts and enhance their problem-solving skills. Incoming students are enrolled in the TARC program, where they attend classroom sessions taught by the mentors in order to learn the basic rocketry knowledge and methodologies essential to the contest. Rockets for Schools is the latest rocketry contest that our club has entered. For it, students are given a high-power rocket kit and asked to design a scientific payload to be flown from Sheboygan, WI over Lake Michigan. Not only does this project offer good training for the process of obtaining an SLI grant, it also gives an additional activity option to first-year club members: while they are not allowed to participate in SLI, our highest-level project, they may participate in the R4S competition. We have modeled our R4S program after the SLI program, placing emphasis on the scientific project and development process. All R4S students are encouraged to seek L1 HPR certification as a part of the R4S program. Our first two R4S teams (2010, 2011) consisted of all firstyear members, and their high scores won additional SLI invitations for the club this for 2011 and 2012 seasons. This year we have continued our summer HPR L1/L2 Certifications program. Two of our alumni, John Schoech and Alissa Chen, attained L2 Certification in addition to a number of L1 certifications obtained by younger club members. This highly successful summer L1 program (outside school year) was invented, coordinated and administered by the SLI-2008, SLI-2009 and SLI-2010 participant, Ms. Zoë Batson. Zoë also worked yearlong as a junior mentor in our club, assisting members with their projects and she has participated in SLI Advanced Rocketry Workshop in New Mexico. We expect her to continue her involvement with our club. Madison West Rocketry actively recruits new members in the fall season: the Freshman Club Carnival, West Fest, Homecoming parade, and daily announcements, all showcase our club’s achievements, appealing to interested individuals. We collaborate extensively with experts at the University of Wisconsin (UW). During our meetings we are able to have analytical discussions with professionals regarding the feasibility and limitations of various potential experimental payloads. We have developed such relationships with eight different departments; this variety provides us with experiences perspectives on our design and objectives. We now have five committed mentors who aid our group throughout all the stages of our well-established rocketry program. They patiently teach us and guide us in the planning, processing, writing, building, organization, and launching of our project. Our mentors dedicate much time and effort throughout the year- we greatly value their compassion and support. -54- Madison West High School New Team SLI 2012 SOW An increasing number of parents are taking interest in supporting our club’s meetings, fundraisers, outreach projects, and launches. They provide us with food and transportation during the cold winter events and launches, and are a great source of encouragement. Additionally, we are seeing an increase in students interested in taking on mentoring roles and work with younger club members. Ms. Zoë Batson (alumni, SLI2008, 2009 and 2010 participant) and Mr. Zuodian Hu (junior student, SLI2011 participant) accompanied our R4S team on their to Sheboygan to provide leadership and assistance as needed. Student mentors in our club enjoy position of authority and respect and their hard work allows senior educators to concentrate on further program developments. -55- Madison West High School New Team Appendices Appendix A: Resume for Adrian 1157 Amherst Drive Madison, WI 53705 aguither@westrocketry.com Education Shorewood Hills Elementary School (2001-2007) Velma Hamilton Middle School (2007-2010) Madison West High School (2010-Present) Activities Rocketry Rocket Club (2011-present) 2010 TARC participant 2011 Rockets for Schools, 2nd place Sports Shorewood Hills Swim Team (2002-present) Madison West Men’s Swimming (2010-present) Madison West Men’s Cross Country (2010-present) Languages English Spanish (4 years) Volunteering Community Service with Madison West Rocket Club Community service with First Unitarian Society of Madison Advanced/Honors Classes Algebra honors (7th grade) Geometry honors (8th grade) Algebra 2 Trigonometry honors (9th grade) Pre-Calculus honors (10th grade) Biology honors (9th grade) -56- SLI 2012 SOW Madison West High School New Team SLI 2012 SOW Appendix B: Resume for Amelie 2244 Rowley Ave. Madison, WI 53726 avbelow@westrocketry.com Academic Experience: Charles-Dickens Grundschule (2000-2004) Randall Elementary School (2004-2006) Velma Hamilton Middle School (2006-2009) Madison West High School (2009-Present) Languages: English, German, French (5th year) Extracurricular Activities and Clubs: Piano lessons (2001-2010) Camp Randall Rowing Club (2009-2010) Madison Youth Choirs (2010) Madison West Rocket Club (spring of 2010-Present) Achievements: Music: 2006 and 2007 Sonatina Festival: Superior Rating 2008 Sonatina Festival: Excellent Rating 2007-2010 National Federation of Music Clubs Junior Festival: Superior Rating MAPTA composition competition: 1st Place (2010) Rocketry: Team America Rocketry Challenge Finalist (2011) Rockets for Schools: 2nd Place (2011) Other: 2009 University of Wisconsin Law School Middle School Mock Trial Competition: 1st Place Hamilton Pride Award (2007-2008) High Honor Roll (2006-2011) Member of the French Honors Society (2011) Volunteer Work: Acolyting at Bethel Lutheran Church (2005-2010) Various piano recitals in nursing and retirement homes (2006-2010) Community service with Madison West Rocket Club Mission Trip to Benton Harbor, Michigan (2009) Mission Trip to New Orleans (2011) -57- Madison West High School New Team SLI 2012 SOW Appendix C: Resume for Caitlin 2205 West Lawn Ave. Madison, WI 53711 cbier@westrocketry.com Academic Experience Franklin Elementary (2001-2004) Randall Elementary (2004-2007) Hamilton Middle School (2007-2010) West High School (2010-present) High Honor Roll since middle school Languages French (2008-2010) Latin (2010-present) Music School Orchestra (2005-2011) Private Violin Lessons (2006-present) Private Piano Lessons (summers of 2008-2011) Extracurricular Activities Science Olympiad (2009-2011, nationals in 2010) Future Problem Solvers (2007-2010, 2nd individual at internationals 2010) Math Team (2008-present) National History Day (2009-2010) Club Gymnastics (1999-2010) School Gymnastics (2010-present) Club Soccer (2001-2010) School Track and Field (2010-present) Midwest Academic Talent Search Finalist (2008 and 2010) Volunteer Experience Community Service Club (2009-2010) Peer Tutoring (2010-present) Monroe Street Fine Arts Center (summer 2011) Outreach through Rocket Club (2010-2011) Filming at Young Shakespeare Players (2011-present) Rocketry Experience TARC Finals (2011) 2nd Place Rockets for Schools (2011) Madison West Rocketry Club (2010-present) -58- Madison West High School New Team SLI 2012 SOW Appendix D: Resume for Han 5001 Sheboygan Ave #114 Madison, WI 53705 hchung@westrocketry.com Academic Experience Ho-Su Elementary School (2001~2006) Bak-Suk Middle School (2007~2008) Saipan International School (2008~2009) Madison West High School (2009~Present) LanGuage: Korean, English (3rd year), Japanese (2nd year) Activities and Achievements Rocketry -

Materials. I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket. 2. Motors. I will use only certified, commercially-made model rocket motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer. 3. Ignition System. I will launch my rockets with an electrical launch system and electrical motor igniters. My launch system will have a safety interlock in series with the launch switch, and will use a launch switch that returns to the "off" position when released. 4. Misfires. If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher's safety interlock or disconnect its battery, and will wait 60 seconds after the last launch attempt before allowing anyone to approach the rocket. 5. Launch Safety. I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of at least 15 feet away when I launch rockets with D motors or smaller, and 30 feet when I launch larger rockets. If I am uncertain about the safety or stability of an untested rocket, I will check the stability before flight and will fly it only after warning spectators and clearing them away to a safe distance. 6. Launcher. I will launch my rocket from a launch rod, tower, or rail that is pointed to within 30 degrees of the vertical to ensure that the rocket flies nearly straight up, and I will use a blast deflector to prevent the motor's exhaust from hitting the ground. To prevent accidental eye injury, I will place launchers so that the end of the launch rod is above eye level or will cap the end of the rod when it is not in use. 7. Size. My model rocket will not weigh more than 1,500 grams (53 ounces) at liftoff and will not contain more than 125 grams (4.4 ounces) of propellant or 320 N-sec (71.9 pound-seconds) of total impulse. If my model rocket weighs more than one pound (453 grams) at liftoff or has more than four ounces (113 grams) of propellant, I will check and comply with Federal Aviation Administration regulations before flying. 8. Flight Safety. I will not launch my rocket at targets, into clouds, or near airplanes, and will not put any flammable or explosive payload in my rocket. 9. Launch Site. I will launch my rocket outdoors, in an open area at least as large as shown in the accompanying table, and in safe weather conditions with wind speeds no greater than 20 miles per hour. I will ensure that there is no dry grass close to the launch pad, and that the launch site does not present risk of grass fires. 10. Recovery System. I will use a recovery system such as a streamer or parachute in my rocket so that it returns safely and undamaged and can be flown again, and I will use only flame-resistant or fireproof recovery system wadding in my rocket. 11. Recovery Safety. I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places. -63- Madison West High School New Team SLI 2012 SOW LAUNCH SITE DIMENSIONS Installed Total Impulse (N-sec) Equivalent Motor Type Minimum Site Dimensions (ft.) 0.00--1.25 1/4A, 1/2A 50 1.26--2.50 A 100 2.51--5.00 B 200 5.01--10.00 C 400 10.01--20.00 D 500 20.01--40.00 E 1,000 40.01--80.00 F 1,000 80.01--160.00 G 1,000 160.01--320.00 Two Gs 1,500 Table 20: Minimum launch site dimensions -64- Madison West High School New Team SLI 2012 SOW Appendix I: High Power Rocket Safety Code Certification. I will only fly high power rockets or possess high power rocket motors that are within the scope of my user certification and required licensing. 1. Materials. I will use only lightweight materials such as paper, wood, rubber, plastic, fiberglass, or when necessary ductile metal, for the construction of my rocket. 2. Motors. I will use only certified, commercially made rocket motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer. I will not allow smoking, open flames, nor heat sources within 25 feet of these motors. 3. Ignition System. I will launch my rockets with an electrical launch system, and with electrical motor igniters that are installed in the motor only after my rocket is at the launch pad or in a designated prepping area. My launch system will have a safety interlock that is in series with the launch switch that is not installed until my rocket is ready for launch, and will use a launch switch that returns to the "off" position when released. If my rocket has onboard ignition systems for motors or recovery devices, these will have safety interlocks that interrupt the current path until the rocket is at the launch pad. 4. Misfires. If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher's safety interlock or disconnect its battery, and will wait 60 seconds after the last launch attempt before allowing anyone to approach the rocket. 5. Launch Safety. I will use a 5-second countdown before launch. I will ensure that no person is closer to the launch pad than allowed by the accompanying Minimum Distance Table, and that a means is available to warn participants and spectators in the event of a problem. I will check the stability of my rocket before flight and will not fly it if it cannot be determined to be stable. 6. Launcher. I will launch my rocket from a stable device that provides rigid guidance until the rocket has attained a speed that ensures a stable flight, and that is pointed to within 20 degrees of vertical. If the wind speed exceeds 5 miles per hour I will use a launcher length that permits the rocket to attain a safe velocity before separation from the launcher. I will use a blast deflector to prevent the motor's exhaust from hitting the ground. I will ensure that dry grass is cleared around each launch pad in accordance with the accompanying Minimum Distance table, and will increase this distance by a factor of 1.5 if the rocket motor being launched uses titanium sponge in the propellant. 7. Size. My rocket will not contain any combination of motors that total more than 40,960 N-sec (9208 pound-seconds) of total impulse. My rocket will not weigh more at liftoff than one-third of the certified average thrust of the high power rocket motor(s) intended to be ignited at launch. 8. Flight Safety. I will not launch my rocket at targets, into clouds, near airplanes, nor on trajectories that take it directly over the heads of spectators or beyond the boundaries of the launch site, and will not put any flammable or explosive payload in my rocket. I will not launch my rockets if wind speeds exceed 20 miles -65- Madison West High School New Team SLI 2012 SOW per hour. I will comply with Federal Aviation Administration airspace regulations when flying, and will ensure that my rocket will not exceed any applicable altitude limit in effect at that launch site. 9. Launch Site. I will launch my rocket outdoors, in an open area where trees, power lines, buildings, and persons not involved in the launch do not present a hazard, and that is at least as large on its smallest dimension as one-half of the maximum altitude to which rockets are allowed to be flown at that site or 1500 feet, whichever is greater. 10. Launcher Location. My launcher will be at least one half the minimum launch site dimension, or 1500 feet (whichever is greater) from any inhabited building, or from any public highway on which traffic flow exceeds 10 vehicles per hour, not including traffic flow related to the launch. It will also be no closer than the appropriate Minimum Personnel Distance from the accompanying table from any boundary of the launch site. 11. Recovery System. I will use a recovery system such as a parachute in my rocket so that all parts of my rocket return safely and undamaged and can be flown again, and I will use only flame-resistant or fireproof recovery system wadding in my rocket. 12.
