Abstract:
1. A gas generator for nitrous oxide decomposition comprising: a reaction chamber for accepting nitrous oxide at a first port and for releasing gas from the nitrous oxide decomposition at a second port, the reaction chamber having an interior and an exterior chamber wall, the interior chamber wall for constraining the nitrous oxide decomposition reaction and the exterior chamber wall defining a jacket between it and the interior chamber wall; and the jacket at least partially enveloping the reaction chamber, an interior surface of the exterior chamber wall and an exterior surface of the interior chamber wall defining one or more channels between the interior chamber wall and the exterior chamber wall, the one or more channels for transporting the nitrous oxide within the jacket from the first port of the reaction chamber and for facilitating the transfer of heat generated during the nitrous oxide decomposition to an incoming source of nitrous oxide, wherein the size and shape of the one or more channels are configured to provide a residence time of the nitrous oxide in the jacket that is shorter than the reaction time of nitrous oxide in the jacket, the incoming source of nitrous oxide being preheated to more efficiently decompose within the gas generator; and a catalyst configured to reduce the temperature required for the nitrous oxide decomposition; wherein the reaction chamber is regeneratively cooled by the incoming source of nitrous oxide.
