SMOS PLM MIRAS Hold-down Release and Deployment Mechanisms

摘要

The hold-down, release and deployment mechanisms designed for SMOS PLM MIRAS have been a challenging activity in terms of design compromise, schedule and cost effectiveness. The existing design coming from previous phase was totally reanalysed to be adapted to a specific mission with extra requirements, making the previous design not totally valid as it was conceptually conceived. Novel concepts were implemented to maintain the feasibility of the design, providing compliance to new and more restrictive requirements. Exhaustive testing proved those concepts and provided the necessary maturity to be valid for flight. This paper is focused on all those new concepts and novelties implemented in phase C/D for the SMOS PLM Instrument Mechanisms as to reach the compliance to the applicable specification.
