Description/Abstract

The performance of an indirect pendulum thrust balance suitable for micro-Newton level thrusters is presented. A design based on a frictionless pendulum with a laser optical lever and detection system makes it possible for thrusters to be mounted independently of the thrust measurement system. This simplifies the process of calibration without having to compensate for electrical connections, flow lines and other equipment. Measurements are not limited by thruster mass and offer thrust measurements down to 80?N. The balance was demonstrated by measuring the performance of two micro propulsion devices; the T5 and T6 hollow cathode thrusters. The T5 generating thrusts from 0.1mN to 1.4mN and the T6 showed thrusts from 0.2mN to 1.9mN.
