Abstract : The patent relates to an open loop on-demand generator system with a two-position injector to provide a variable gas flow for a reaction control system. The injector system includes two two-position injectors located on opposite sides of the gas generator to provide a constant pressure to match the flow demand for each thrust step. Each injector includes a swirl device to provide swirled fuel at idle flow as well as maximum demand flow. Each injector also provides four intermediate thrust steps between idle flow and maximum demand flow.
