Acceptance Testing of the Advanced Electric Propulsion System Qualification and Flight Thrusters

This work presents a summary of the Acceptance Test Program performed on the qualification and flight units of the 12 kW Advanced Electric Propulsion System. This test program is led by Aerojet Rocketdyne and consists of acceptance vibration, acceptance hot fire, and final functional measurements and inspections. As of this work, acceptance testing has been completed on one qualification unit and two flight units. In general, no statistically significant unit-to-unit variation was measured and all three units successfully completed acceptance testing and are ready for integration onto the Power and Propulsion Element or have proceeded into environmental qualification.
