AbstractBusek proposes to develop a flight version of a high power Hall Effect thruster. While numerous high power Hall Effect thrusters have been demonstrated in the laboratory, no flight qualified options exist. The baseline thruster would be tentatively sized at the 15kW power level. Busek proposes to work with NASA to improve upon laboratory designs by incorporating both NASA and Busek unique HET product knowledge. Specific features to be implemented include the use of Hiperco magnetic alloy, improved magnet field distribution using magnetic shielding, high temperature magnet coils and an advanced propellant distribution methodology. Particular attention will be paid to thruster lifetime through a combination of magnetic modeling and erosion analysis using the JPL developed Hall-2DE code.In Phase I, we will prepare a detailed engineering design of the baseline thruster Using internal funds and therefore at no cost to the Phase I effort, Busek will procure the Hiperco raw material for the thruster, have it forged to rough dimensions, heat treated and samples sent to an outside laboratory for magnetic property characterization. This material will be held in inventory to support the thruster build in Phase II. ULA will provide at no cost to NASA engineering support by performing a top level assessment and preliminary system engineering for incorporating a 30kW propulsion module (with two15kW thrusters) with the MegaFleX and RollOut solar array onto the ESPA. In Phase II we will build and conduct performance and environmental testing of the thruster to raise the maturity level to TRL 6 at the end of the Phase II program.
