Rotary Actuator Based On Shape Memory Alloy for Operation in Mars
A Qualification Model (QM) and qualification tests will be presented in this work. Results of Qualification tests will be presented in this paper in order to prove the fitness of the designed actuator as a simple and effective solution for space application, and for other where mass reduction and high reliability is demanding but movement high accuracy is not so important. A Flight Model of this device has already been developed and acceptance tests have been passed and will be presented in this work.
The actuator presented is designed and qualified to withstand an impact inertia up to 2000 g and work in a harsh environment with a temperature range of -90ºC to +30ºC under vacuum conditions. The use of Shape Memory Alloys on the designed actuator presents several advantages of lightweight, high force to weight ratio and low volume.
