| Abstract: | Satellite attitude control system (ACS) thrusters are often required to operate at an extreme range of conditions. These include pulse mode duty cycles, propellant pressure, propellant temperature and initial thruster temperatures. The impacts of test conditions on thruster, operating modes can be seen in mixture ration (MR), thrust (i.e. chamber pressure), propellant flow rates and hardware temperatures. Combining these conditions together with requirements for demonstration of performance, life (throughput), cycles and cold starts can result in a large test program with a high number of tests in order to capture all possible combinations. During the design of thruster qualification programs, the value for testing all combinations of conditions is often questioned in light of the high cost of testing. Test program scope reduction is typically achieved through the establishment of a small number of fixed conditions which are assumed to encompass the greater range of conditions. This leads to questions of the optimum selection of test condition combinations to provide a sufficient understanding of performance and thruster life while minimizing cost |
