Thermal Radiator with Electrodynamic Dust Shield (EDS) (TREDS)

Active TRL 4 (started at 4, targeting 5)

Description

This project seeks to integrate the Electrodynamic Dust Shield (EDS) with thermal radiators to reject heat and prevent dust buildup on various Thermal Control Coatings (TCC) without significantly impacting thermal performance. Keeping surfaces dust free is essential for thermal radiators as the dust acts as both a blackbody and a thermal insulator, essentially absorbing more sunlight and preventing the radiator from dissipating heat. The lack of heat rejection on dusty surfaces will result in radiator(s) being oversized (mass impact) and could potentially lead to a catastrophic system failure due to overheating. With an EDS integrated into the radiator system, dust impacts can be mitigated.

This project develops solutions to dust contamination of thermal radiators that may be used on critical systems needed for mission success on the Lunar and Martian surfaces, including manufacturing of a scaled-up version of the Thermal Radiator EDS.

Key objective of the project is to test a few commonly used thermal control coatings for EDS compatibility

Benefits

TREDS is expected to minimize radiator sizing, improve radiator performance, and maximize lifetime of radiators.

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
