Abstract
When passively actuated in response to changes in CubeSat temperature, deployable radiators are capable of thermal regulation without the need for an electrical control system. However, these radiators face challenges in the transfer of heat from the CubeSat interior to the deployed radiator panel. In this work, we explore an approach that provides passive radiator actuation and efficient thermal transfer by combining a Two-Way Shape Memory Alloy actuator with an integrated heat pipe. Preliminary work focuses on the characterization of the Two-Way Shape Memory Effect (TWSME) in bending of Nitinol rods and tubes of varying outer diameters.
