| Research Abstract |
The purpose of this study is to propose a new thermal control method under periodic heating environment and to demonstrate its feasibility. A new small loop heat pipe was developed as a heat transport device for this method, and thermal controllability against large heat load change and environmental change was evaluated under both atmospheric and vacuum conditions. A new instrument to simulate lunar thermal environment was fabricated. A thermal model for periodic heating environment was also developed based on the evaluation of thermophysical properties of the lunar regolith stimulant.
