Technical Session XI: Orbital Manuvering
Abstract
Nitrous oxide catalytic decomposition is an on-going research programme at Surrey. This research supports the development of novel multi-mode propulsion system concept for a small satellite. At present the efforts are concentrated on the issues supporting the development of restartable nitrous oxide monopropellant thruster. This thruster is considered suitable for small satellite station-keeping and phasing. The thruster’s operational principle employing nitrous oxide catalytic decomposition is described. The thruster’s catalyst pack sizing can be performed by application of the given loading factors and described axial temperature profile measuring technique. Ergun’s equation is recommended for assessment of the pressure drop through the catalyst pack. The maximum flows supported by the self-pressurising nitrous oxide feed system are discussed.
