SBIR 95-1 SOLICITATION
LIGHTWEIGHT HEAT PIPES INTEGRATED INTO MICROSPACECRAFT STRUCTURES
As satellite payloads and solar arrays continue to become smaller and/or lighter, the weight and volume contributions of the satellite
structure and thermal bus become more critical. Reductions in payload volumes also lead to higher waste heat densities, aggravating the heat
transport/rejection requirements of the thermal bus. The combination of these factors complicates the bus design, necessitating development of
more capable, more compact thermal bus concepts. New microspacecraft buses must therefore seek to eliminate parasitic weights and volumes
by combining thermal, structural and electrical functions into a seamless unit.
Saddleback Aerospace has generated two innovative concepts to meet the needs of low-cost microspacecraft. These concepts
minimize system weight and volume, while providing robust thermal management capability throughout the satellite structure. The concepts are:
1) a laminated foil heat pipe honeycomb to replace current low-conductivity honeycomb wall panels, and 2) a laminated foil honeycomb
propellant/pressurant storage concept which eliminates the parasitic weight/volume of conventional propellant tankage by providing storage in
the satellite walls. In the proposed effort prototypes for each of these concepts will be fabricated and tested to demonstrate the feasibility of these
Potential Commercial Applications:
The proposed study will directly support the growing market for improved satellite services and supporting
satellite technology. The results can also be used for the compact, thermally isolated electronics and actuators
of the More Electric Aircraft. More generally, the cooling techniques proposed here will have application
throughout the electronics and communications industries.
