Design, verification and testing of the International Space Station photovoltaic radiator
- Lockheed Martin Vought Systems, Dallas, TX (United States)
The Photovoltaic Radiator (PVR) is designed to reject the waste heat of the PV power generation and storage system. The requirement has been added to provide heat rejection for the Early External Active Thermal Control System to support the Assured Early Research phase of the International Space Station (ISS) Mission. The new requirement has resulted in the reanalysis and some redesign of the hardware. In addition, the new use of the PVR hardware has resulted in a significantly earlier launch date. This paper describes the PVR design with emphasis on the design changes made to incorporate the new mission requirements. The verification methods are discussed and the results of analysis and testing accomplished to date are summarized. Single panel thermal and modal tests have been conducted. Ambient deployment testing and thermal vacuum deployment/thermal performance tests have also been successfully conducted. Additional testing planned include a repeat of the single panel thermal vacuum test for the silver Teflon coating, a stowed acoustic test, a qualification test of the heater system and an acoustic and modal test of three of the units installed on the Flight 4A launch package. All of this testing must be completed by the end of 1997. Structural and thermal analyses have been conducted for the new design requirements and have resulted in several design changes to the structure and thermal design. Thermal analysis is continuing to determine the final thermal design.
