Surrey Research on Nitrous Oxide Catalytic Decomposition for Space Applications

Abstract

Nitrous oxide is introduced as a rocket propellant for small satellites. The reasons for using this propellant on small spacecrafts are discussed. Potential space applications of nitrous oxide are listed. A nitrous oxide catalytic decomposition technique is suggested for restartable spacecraft propulsion. Theoretical performance of a nitrous oxide monopropellant thruster is shown. Basics of nitrous oxide catalytic decomposition are given. Operating principles of a nitrous oxide monopropellant thruster are described. The design of the test apparatus and the set-up for nitrous oxide decomposition are given. Up-to-date achievements of nitrous oxide decomposition research at Surrey are reported. Future design features of nitrous oxide monopropellant thrusters are discussed. A conclusion about future research on nitrous oxide catalytic decomposition is given.
