NUMBER 7
01-02 Season Kick-Off
Flywheels for Power and Control
Flywheels promise an order of magnitude increase in
performance and service life in many NASA
applications including spacecraft, launch vehicles,
aircraft power systems, uninterruptable power
supplies, and planetary rovers. The Integrated Power
and Attitude Control System (IPACS) program
combines existing reaction wheel technology with
flywheel energy storage concepts to combine attitude
control and electrical power components. The NASA
effort is aimed at both developing working flywheel
systems and advancing the supporting technologies.
Work is accomplished in partnership and cooperative
arrangements with other government agencies,
including Airforce Research Laboratory, Defense
Advanced Research Projects Agency (DARPA) and
Oak Ridge National Laboratory (ORNL), academia,
and industry.
Our first dinner meeting of the new 2001-2002
season will feature a report on this exciting
technology. Honeywell Engines & Systems in
Tempe, Arizona was selected as the prime industry
contractor to develop and demonstrate this
technology on a 3-axis test bed (ASTREX, an
existing 3-axis attitude control test facility mounted
on a spherical air bearing). Steve Abel, the team
leader for the IPACS effort at Honeywell, will
discuss the development, status, and future of the
program. Details on the dinner meeting are below.

AIAA Trial Membership Program
Help enable qualified, non-member aerospace
professionals to experience AIAA membership
benefits-FREE-for 9 months!
How It Works:
- Our section has received 10 Trial Member
Applications and brochures.
- Request one from a Section Officer and pass a
brochure and activation form on to your nonmember
colleagues.
- To activate a trial membership, the non-member
need only to complete a "Trial Member Application
Form" and send it to AIAA.
- All trial members will be welcomed to AIAA and
the Trial Member Program.
-Trial memberships will begin 1 November and run
through 31 July.
Criteria for trial member candidates include a
Bachelor's degree in science or engineering, or
equivalent qualifications through professional
practice, and will not have been an AIAA member
for at least five years. A total of 600 trial
memberships will be issued in 2002 on a first come
first serve basis. So, act now and secure as many of
the trial memberships for our section as possible.
At anytime during the 9-month free-membership, the
trial member can elect to become a dues-paying,
active member of AIAA and enjoy uninterrupted
member benefits.
Let’s try to give this a try. We’ll have forms at the
next few dinner meetings or call Ron Roden and he
can mail one to you or your colleague. This program
will only be as successful as the time and energy all
of our members commit to it!!
Remember that all Trial Member Applications must
be received by AIAA by 15 October 2001.
The University of Arizona’s
Student Satellite Project
The Student Satellite Project (SSP) at the University
of Arizona was initiated in 1996, by Department of
Physics Professor K.C. Hsieh and Aerospace and
Mechanical Engineering Professors Wayne Chen and
Ernie Fasse. The initiators felt that the University of
Arizona had all the right ingredients to support such
an endeavor including a strong research program in
space-related sciences and the engineering resources
to make it happen.
In order to provide some design constraint for this
process, and also to ensure the best possibility of
success for the eventual mission, the launch
opportunity of the Small Shuttle Payloads Project
Office Hitchhiker Ejection System (HES) was chosen
from the outset. The HES is an emerging capability
on the Space Shuttle for ejecting a payload from a
Get Away Special (GAS) canister, placing it into an
orbit similar to the Space Shuttle's. The availability of
launch opportunities coupled with the HES design
constraints mandated by NASA provided for a nice
set of constraints for designing a spacecraft mission.
Some might be quick to point out the disadvantages
of HES, however, which include the 1-year orbital
lifetime, and the requirement to design for launch
from a man-rated vehicle.
With these constraints in mind, over 80 volunteer
student respondents were assembled into 7 teams,
comprising 6 design subsystems. The student teams
were tasked with finding a faculty advisor and
submitting a "Letter of Intent to Propose" one month
later. Full proposals would follow on April 14, 1997.
An Evaluation and Selection Panel (ESP) was
assembled from distinguished individuals of the
University and local industry to evaluate the
proposals. They announced the selected proposal
ideas on April 28th, and the Student Satellite Project
was formally organized on May 8, 1997.
Since then the student teams have enthusiastically
pushed the project ahead. The designs of the
subsystems have progressed and matured both as
independent units and as part of an overall, coherent
system. The progress of these designs was validated
on November 22, 1997 at a Conceptual Design
Review before the members of the ESP, and now
advances towards a Preliminary Design Review in
early 1999. Student involvement in the project has
continued at a high level of approximately 60 to 85
students - even during the summer - as eager recruits
have replaced the graduating members of SSP, and
students have defended graduate theses and
conducted "capstone" senior design projects within
the context of their involvement in the project.

The new SSP will build a series of "CubeSats," tiny
standardized spacecraft that can be designed, built,
launched and operated in orbit by undergraduate
students within one to a few semesters. Although
each CubeSat is a mere 4- x 4- x 4-inch box weighing
at most a kilogram (2.2 pounds), these space vehicles
can be used for serious research.
This is where AIAA gets involved. Over the last few
years, members of the Tucson section have been
assisting the UofA in this program. As a facet of
their Evolution of Flight program and by involving
the Space Grant Program (http://spacegrant.arizona.
edu/national/), they are trying to take it to the
national level. There is a lot of potential to this
project, and it already has a lot of momentum. The
AIAA has the opportunity to help as a major sponsor
(of organizational talent). The idea is to have all 52
Space Grant offices participate by contributing a
CubeSat, one for each state, Puerto Rico, and the
U.S. Virgin Islands. Not all of the states/offices have
the wonderful resources available to us in Arizona,
but the plan is to send a flotilla of 52 cubes to
Mars...one from each Space Grant office.
Such a swarm may actually allow for interesting
science and characterization, such as the mapping of
global fields. However, its greatest benefit is the
educational aspect. For only tens of thousands of
dollars, even small institutions can give their students
the opportunity to actually build a satellite and be
part of an exciting national space project!
It may seem small, but a 4 inch satellite can keep a
dozen students and several faculty members very
busy during the year...and when you put together
large numbers of these cubes, the possibilities are
amazing.
