SBIR 95-1 SOLICITATION
A NOVEL RADIATOR FOR AN EMU
Advanced technologies are needed to reduce the weight and volume of
the thermal control systems for the Portable Life Support System
(PLSS). TDA Research, Inc. (TDA) has identified a novel radiator
that can reject heat to space during an ExtraVehicular Activity
(EVA) in proportion to the highly variable thermal loads in the
At a low thermal load, a portion of the radiator freezes, reducing
the effective radiating area. When the heat load rises, the frozen
section thaws and the effective radiator area increases to reject
the higher thermal load. Since the radiator will be fabricated
into the outside shell of the PLSS, it severs two functions
simultaneously, minimizing the weight impact on the PLSS.
During Phase I we will select the specific system configuration,
prepare a computer model of the radiator, and conduct a small scale
Potential Commercial Applications:
The novel radiator will find application to un-manned spacecraft
and special purpose applications in manned spacecraft.
