Tech Aerospace Engineers Selected for NASA Reduced Gravity Flight
Tech's Aerospace Enterprise student team was selected to test
their nanosatellite in zero gravity on KC-135 airplane at
an altitude of 36,000 ft. over Texas. Shown at left, MEEM

Aerospace Enterprise Team is competing with nine other universities
to build the best probe for the NASA space shuttle launch
scheduled for 2006- 2007
The MTU KC-135 Team is an undergraduate research team participating
in the NASA Reduced Gravity Student Flight Opportunities Program
(RGSFOP) at Johnson Space Center. The KC-135 Team operates as
a design team as part of the MTU Aerospace Enterprise. Recently,
The Reduced Gravity Office selected the MTU KC-135 Team to fly
in an experiment on dynamic behavior of an inflatable boom (with
end masses). The boom and end masses are part of the MTU Aerospace
Enterprise's University Nansosat 3 Program.
goal of the proposed experiment is to understand the fundamental
dynamic behavior of an inflated space structure and how this
behavior will impact attitude control of the MTU HuskySat.
The four primary objectives are as follows:
effects of gravity-dependent boundary conditions on the modal
response of the boom in each state. Determine stiffness of
the boom in each state for small deflections. Determine perturbation
amplitude at which the boom's dynamic response deviates from
solid mechanics' theory. Document dynamic behavior of the
boom for large oscillations.
• Understand the fundamental dynamic behavior of an
structure and effects of gravity induced boundary conditions.
• Responses will be induced using a multiple reference
roving impact hammer test
• Data will be used to predict stiffness of the boom
and settling time of
spacecraft when disturbed
• Generate control laws for MTU HuskySat

•“Free-float” experiment examining tip-offs
due to antenna deployment
