Abstract:

The main activities on the Flexible Rolled-Up Solar Array FRUSA program during the ninth quarterly reporting period consisted of assembly of the developmentqualification model of the orientation mechanism, solar array, drum mechanism, control electronics unit CEU, and solar cell electronics unit SCEU. Cells, simulated blanks, and busses were bonded to the two qualification model panels. The panels were connected to the drum mechanism, which had been assembled without the interface wiring and water table deploymentretraction tests on the complete assembly successfully conducted. Functional acceptance testing of the CEU and the SCEU have been initiated. The instrumentation conditioning unit ICU is still awaiting the two hi-reliability capacitors before acceptance tests can be initiated. Fabrication of detailed parts for the power conditioning unit PCU and batterycharge controller are nearing completion, and detailed parts drawings and the schematic have been released for the load bank assembly. An updated FRUSAAgena wiring diagram, Space Experiment Plan, and Flight Model Design and Test Specification have been completed and submitted to Wright-Patterson Air Force Base.
