This work presents a summary of the first detailed performance assessment of the Advanced Electric Propulsion System (AEPS) Engineering Test Unit 2 (ETU-2) thruster produced by Aerojet Rocketdyne at the throttle conditions most relevant for AEPS application on the Gateway Power and Propulsion Element (PPE). First, an assessment was performed of ETU-2 performance and backpressure sensitivity at the previously-tested throttle points of 300 V/6.25 kW, 400 V/8.33 kW, 500 V/10.42 kW, and 600 V/12.5 kW that confirmed ETU-2 and the test facility were both operating nominally and consistent with historical baselines. ETU-2 performance and stability were then assessed throughout the PPE throttle range of 2.6-12 kW and shown to be in-family with predictions based on the scaling of previous results. Taken together, these results will help inform application of AEPS on PPE as the AEPS design progresses towards its Critical Design Review.
