“…Based upon previous work by Ketsdever, 12 the system was redesigned and optimized for use with the capillary discharge PPT. The resulting stand had a time resolution on the order of 1 µs and was capable of measuring total impulses up to 150 mN s with a resolution of 0.4 mN s. 13 The thrust stand was calibrated through the use of computer controlled electrostatic combs as described in work by Selden. 14 Due to the comparatively large forces imparted by the capillary discharge, the electrostatic combs described by Selden were rebuilt and scaled up to provide a maximum force of 5x10 −2 N .…”

A dynamic-force extraction, based on the least-squares method, is proposed for micro-propulsion testing. Having modeled the displacement oscillation of a micro-newton torsional pendulum, the time evolution of the dynamic force may be calculated if the stand constants are well calibrated. According to the linear characteristic of the motion equation, a reconstruction of the dynamic thrust reduces to solving linear equations. The simulation analysis shows that the error is affected by the sensor noise and the low-pass filter as well as the sampling rate. Validation experiments were performed showing that this method reconstructs the dynamic force well up to 8 Hz with an error less than 15 μN. The noise-induced error moreover varies little with frequency.
