Abstract

A comparison of the experimental results of a nitrous oxide cold gas thruster with the predicted performance from a numerical simulation of nozzle operations is discussed. Tests were conducted in a vacuum chamber to verify analytical predictions of both nitrogen and nitrous oxide. Preliminary results indicate an Isp for N20 of 61, and an Isp of 69 for N2. Based on the results of this research, parameters are presented for a nitrous oxide based reaction control system for a small spacecraft currently under development.
