P&E Group TC Participation in AIAA Sections, Committees & Activities TC participation/activities with AIAA sections: – No official joint activities with local AIAA sections, however, local AIAA sections have been contacted with regard to participation/involvement in IECEC conference Standards: Large number of TC members involved in AIAA Standards activities. Substantial & active involvement in the following Standards activities: – AIAA Standard - Qualification and Quality Requirements for Space Solar Cells (S-111) – AIAA Standard - Qualification and Quality Requirements for Space Solar Panels (S-112) – AIAA Standard - Electrical Power Systems for Unmanned Spacecraft (S-122) – APS TC members are part of an international committee trying to create an ISO standard on solar cells and panels. – APS TC members are involved with reviewing Aerospace Battery Qualification Standard TOR-2007(8583)-1. – APS TC committee members are currently and actively involved in modifications to AIAA Standards (S & S headed by Henry Brandhorst, and S122 headed by Winnie Choy) Education: – APS TC puts together the Aerospace Power Systems course, held annually at the Space Power Workshop – APS TC has generated a draft Education Charter and is being reviewed by TC for release. Policy: One TC member emeritus (Doug Allen) is involved in this committee

P&E Group APS-TC 2008 Significant Accomplishments The Aerospace Power Systems Technical Committee has been extremely busy and involved over the past year with various activities. A major activity has been the operation and the long-range planning of the IECEC, which included a decision to co-locate with the JPC in 2009 and involving other. The IECEC is jointly organized with the Terrestrial Energy Systems TC and is the major conference for the APS Technical Committee since it is one of the few conferences that addresses the breadth of aerospace power system technologies covered by this TC. The TC provided substantial organizational and technical support for the IECEC this year. The other major accomplishment by this TC has been its involvement in the development of various standards for the aerospace community. Significant work over the past year was put into the committee to establish and complete AIAA Standard S-122: Electrical Power Systems for Unmanned Spacecraft. Earlier involvement in the AIAA Standards S and S on Solar Cell and Array Qualification and Quality Requirements now has many APS TC members involved in meetings to discuss clarification and possible changes to these documents in response to comments from industry/Government. The TC has also been asked to participate in revising a 1978 AIAA Position Paper on Solar Power Satellites. This request is currently being evaluated by the committee.
