Deployment Mechanisms

Scientific paper

Based on the EADS CASA Espacio experience on flight deployment mechanisms, conventional spring motor appears like the most light and reliable method to perform one-way deployments, but this kind of deployment requires a controlled final speed to avoid the use of dampers and/or similar devices to minimize end-of-travel shocks. In order to avoid sophisticated mechanisms based in centrifugal or electromagnetic principles to get a fully controlled deployment speed EADS CASA Espacio has qualified a simple and reliable mechanical speed regulator without thermal and/or electrical powering or commanding. This Mechanical speed regulator (Patent: P9600684 - 27/03/00) has been developed and qualified in the frame of several space programmes: MINISAT Satellite (May 1997), DESAT project for HISPASAT C Satellite (1998), and ASAS and MIRAS deployable antennas (1999 - 2000) with a regulation capability up to 10 Nm. An extended qualification test campaign was performed to increase the functional environmental range.
