DELPHRAD: Lightweight & High Performance Deployable Radiator Development Program
Alcatel Space Cannes has successfully designed, manufactured and ground tested a two-LHP lightweight and high performance deployable radiator (“DELPHRAD”) in the frame of a development program co-funded by ESA. DELPHRAD is a follow-up of the STENTOR deployable radiator flight experiment sponsored by CNES (“Centre National d'Etudes Spatiales”; French National Space Agency). The STENTOR and DELPHRAD LHPs were designed, manufactured and delivered by EHP Nivelles (formerly SABCA Brussels). DELPHRAD features significantly lower mass budget than that of STENTOR with slightly better thermal performance. The considerable mass improvement is achieved essentially by the direct condensation thermal concept and the use of corrugated flexible lines. Some technological innovations contribute to facilitate the deployable radiator thermal sub-system manufacturing and its integration in a satellite system.
