抜粋

This paper presents the development of a lightweight 100W-class re-deployable radiator with environmentadaptive functions. This radiator, reversible thermal panel (RTP), which consists of flexible high thermal conductive graphite sheets and a single crystal shape memory alloy as a passive reversible actuator, changes its function from a radiator to a solar absorber by deploying/stowing the reversible fin upon changes in the heat dissipation and thermal environment. A deployment/stowing test in atmospheric condition and a thermal vacuum test were conducted. The fin deployment angle could be changed from 0 deg to 140 deg with the change of the RTP temperature from -40 C to +40 C in the deployment/stowing test using a constant temperature chamber. Autonomous thermal control function was demonstrated in the thermal vacuum test although the fin could not be entirely stowed under cold condition.
