摘要： An emergency hydraulic power supply for an aircraft or the like, including a hydraulic pump arranged to be driven by a turbine in turn driven by hot gas from a decomposition chamber, a fuel pump driven by the turbine for supplying fuel to the decomposition chamber, primary flow control valve means in the pump outlet for controlling fuel flow responsive to turbine speed, an ignition chamber communicable with the decomposition chamber and having a start grain for initiating turbine operation to start the fuel pump, a secondary control valve in the pump outlet, and control means for sensing turbine speed and opening the secondary valve when the turbine attains a speed indicating the start grain has about burned out, and closing the secondary valve in the event that the turbine attains a speed indicating the primary flow control valve means is inoperative to control turbine speed.
