Abstract:

This report presents the results of a parametric analysis, evaluation and comparison of space electrical power systems capable of meeting a set of mission requirements. The parameters include continuous power 300 or 600 W, peak power 2, 3.5 or 5 kW, duty cycle 5, 10 or 20 and mission duration 1 to 12 months. The spacecraft is defined to be in a low circular polar orbit and the power systems are to be available in the 1970-1973 time frame. Six types of power systems solar cellbattery, fuel cell, fuel cellbattery, solar cellbatteryfuel cell, solar cellfuel cell, and radioisotope thermoelectric generatorsbattery were evaluated for possible application to such missions. Evaluation and comparison criteria include mass, volume, procurement costs, reliability and spacecraft integration factors. Author
