Abstract

The Coronagraph version of the Terrestrial Planet Finder (TPF) mission relies on a large-optics, space-born observatory, which requires extreme stability of the optics in the presence of thermal and dynamic disturbances. The structural design requires balancing of stringent constraints on launch packaging with unusually tight response requirements for thermal and dynamic environments. The minimum-mission structural model (pre-phase A, point design) includes a deployable, pre-tensioned membrane sun-shield and solar-sail, a 10m long deployable secondary support structure, and a light-weighted 6m diameter monolithic glass primary mirror. We performed thermal distortion and dynamic response analyses in order to demonstrate feasibility, quantify critical sensitivities, and to identify potential problems that might need to be addressed early on.
