Meeting: GLAST Preliminary Design Review, January 8-11, 2002 Subsystem: Thermal RFA Number: 33 Originator: D. Hewitt/T. McCarthy, Code 545, 301-286-5115 Response Accepted/ RFA Closed: _________________ (Originator’s initials) Specific Request: Conduct a delta mechanical/thermal PDR to evaluate technical, cost and schedule impacts of the thermal changes necessary to meet requirements with margin. Supporting Rational: The PDR design did not meet requirements and did not factor in the impacts of moving the radiators outboard and/or additional heat pipes. Response: Agreed. A Delta PDR for the mechanical/thermal subsystem was held in July 2002. As a result of a successful review, the mechanical/thermal subsystem preliminary design was baselined.
