[PDF] A Thrust Stand for uquid Propellant Pulsed Plasma Thrusters

29 Jun.,2022

A torsional-type thrust stand is designed, to precisely measure impulse bits produced by pulsed plasma thrusters (PPTs) in vacuum. This stand is capable of measuring low in]pulse rauging from 10 to 1000 uNs. Investigations into extremely low impulse measurement have been hampered by facility vibrations. We discuss about relation between background noise and vibrations induced by it, and optimum damping ratio, that makes Signal-to-Noise ratio maximum, is shown. Using this thrust stand, the performance of a liquid propellant PPT was measured.
