Abstract :
The design and development of a retractable, retrievable, and reusable advanced rigid array solar cell array is presented. The first application will be for EURECA in a 5 kW version. The array is designed for ten years in low earth orbit (LEO) and five shuttle launch-landing cycles. The design of new mechanisms to incorporate the retraction and relatching requirements is presented. The setup of a monitoring and electronic control system for the functional requirements is shown. A selection of materials and processes suitable for LEO missions regarding atomic oxygen erosion and thermal cycling is also shown. Rigorous fracture control measures to satisfy the reusability requirements, in view of shuttle safety regulations, are presented.
