A proposal by Roccor LLC of Louisville, Colo., to develop lightweight, flexible thermal energy management panels for CubeSats and other small satellites is one of 399 projects selected by NASA this week to support future missions into deep space. The thermal panels incorporate paraffin phase change material inside a metal case with an internal metal woven mesh to protect the electronics aboard miniaturized satellites.
Roccor's proposal describes the potential applications:
"The primary NASA target application for the proposed space-rated PCM panel technology is future NASA CubeSat and SmallSat spacecraft for which thermal control of on-board electronics is a major bottleneck in the system design. In particular, the proposed technology will enable efficient thermal control by maintaining a constant temperature heat sink or heat source for a range of electronic components in rapidly changing thermal environments. The PCM panel is being designed as a lightweight and flexible component, yet having high thermal capacity, requiring less mass and volume than currently used carbon-fiber and aluminum honeycomb composite panels."
Two other Roccor proposals were approved for Phase I development. Each will receive six-month contracts valued at up to $125,000. Watch the video below to learn more about the CubeSats being developed at NASA's Jet Propulsion Lab in California.
