Abstract : The main activity on the Large Retractable Solar Cell Array (LRSCA) program during the third quarterly reporting period consisted of the completion of the analysis of a majority of the major subsystem components, start of detailed drawings, completion of the preliminary qualification model design and test specification, EMC Guidelines, failure modes and effects analysis, maintainability and reliability analysis, as well as completion of the solar array test bed. Detailed design reviews were also held during this period on the solar array, solar array storage drum and mechanism, and the orientation linkage mechanism and control electronics. Test and development activity consisted of test verification of subsystem elements, such as the boom length compensator mechanism, cell and substrate material processes, as well as the performance of panel tension tests at room temperature.
