Abstract : A capillary discharge based pulsed plasma thruster is currently under development at the Air Force Research Laboratory. A torsion thrust stand has been developed to simultaneously measure the shot by shot total impulse and propellant mass loss of the thruster, yielding a per shot specific impulse. Competing design considerations affecting the performance of the thrust stand has lead to an optimized diagnostic tool capable of measuring total impulses up to 150 mN s with a resolution of 0.4 mN s and mass losses up to 18g with a resolution of 1 mg.
