Advanced Modular Radiator
This proposal introduces advances in the performance and packaging of modular radiators for heat flow modulation on operationally responsive space (ORS) smallsats. The proposed concept is based on the loop heat pipe (LHP) thermal switching radiator. Two key advancements proposed are: 1) use of a novel submicron pore size, high permeability wick that offers higher performance and lower cost than traditional titanium wicks typically used in ammonia LHPs; and 2) a low profile, integrated LHP/insulation/radiator module that can be quickly bolted to a satellite bus panel, or payload panel and deliver high switch ratio heat flow modulation. The Phase I project will involve novel wick development and characterization, and advanced modular radiator concept development, modeling and preliminary design. This work provides the foundation of fabrication and testing of the advanced modular radiator in Phase II. BENEFIT: The proposed advanced modular radiator will is a key component of a plug-and-play thermal architecture that allows rapid smallsat assembly using off the shelf thermal components selected based on mission requirements.
