Thrust Measurements with EPPDyL at Princeton U.

Thrust Measurements - in collaboration with EPPDyL at Princeton University

EPPDyL thrust stand (See below) was designed to accurately measure impulse bits of pulsed plasma thrusters (PPTs) within the range of 10-4 – 10 Ns.

Theoretically predicted to be capable of measuring low steady state thrust, as low as 20 mN.

Experimentally determined during each measurement:

• ‘instantaneous’ equilibrium position

• effective spring constant
