Hanging, torsional and inverted pendulum thrust stands are briefly discussed followed by an in-depth discussion of the University of Illinois at Urbana-Champaign’s inverted pendulum thrust stand. Thermal drift was investigated on the thrust stand with component level, sub-system level, and system level testing. Thermal drift data were analyzed and are discussed with recommended mitigation strategies. Relative error was calculated on the thrust stand, and an example relative error calculation was performed for a low power Hall thruster. Facility test setups are discussed with pumping speed experimentally calculated. The SPT-50 and SPT-70 were hot fired and thrust values were measured. The setup and electrical configuration are discussed for the thrusters. Thrust values are then compared with literature to validate the thrust stand. 2025-12 Thesis https://hdl.handle.net/2142/132603 Copyright 2025 Justin Shell Aerospace Engineering Aerospace Engineering University of Illinois Urbana-Champaign M.S.
