Solar Array Root Hinge Based on Shape Memory Alloy (SMA) Actuator
Abstract
The Solar Array Root Hinge based on Shape Memory Alloy actuator was designed and developed as a generic application for solar array of communication satelliteThe interest of this development was to implement for the first time at TAS level a low-cost, reliable and lightweight actuator technology for solar array deployment.This paper presents :- The design of the root hinge, including SMA actuator description- The development logic based ono Qualification status of the SMA actuatoro Delta design of the SP ACEBUS generic root hinge- The qualification test sequence (functional test, vibrations, TVAC)Results of a deployment test performed on ground at SMA rod, root hinge, then solar array level are presented.
