Abstract
This paper presents a study on the optimization of a lunar lander for surviving extremely cold lunar nights by using completely passive thermal control. The effects of parameters such as shape, thermal conductance, and effective emissivity on temperature swings of the lunar lander were numerically analyzed. On the basis of the results, some candidate models were formed and the temperature swings of each model were compared. Then, from the viewpoint of feasibility, a particular model was selected. The model was scaled and experimental comparisons were performed. These comparisons proved the efficiency of the proposed model, both numerically and experimentally.
