HAKUTO lunar rover thermal control design validated by vacuum thermal balance test
1 reports · 1 sources
Researchers including Toshiki Tanaka published a study on the thermal control strategy for the flight model (FM) of the micro lunar rover HAKUTO, whose thermal interface design was validated through a vacuum-environment thermal balance test. The study divided the rover body into 6 radiating surfaces to build an analytical thermal model, and, combining lunar radiation, solar albedo, and lunar regolith thermal conductivity, determined the avionics mounting locations and solar panel angles, keeping mass within 4 kg; after refinement through numerical simulation, validation was completed. The study was presented in October 2018 at the 69th International Astronautical Congress held in Bremen.
