Abstract
Mini/micro nozzles are used in digital propulsion systems for generating milli/micro thrust. Such systems are used in satellites for precise control and positioning. The measurement of milli thrust which is of the order of few Newton requires specialized measuring systems. In the present work, a force sensing resistor (FSR) is used to measure such low valued thrust. A commercially available FSR is calibrated using standard weights. The FSR response to added loads is recorded using a NI-DAQ (National Instruments - Data Acquisition) system and signals are analyzed using LabView package in a desktop. The calibrated values match well with the standard charts and percentage of error is calculated. The thrust produced by the fabricated nozzle setup is measured using FSR in the same arrangement and compared with the analytical equations. The measured values are in good agreement with analytical results.
