Abstract: A method and apparatus for rapidly generating a controllably variable flow of motive gas at an elevated temperature and pressure in a gas generating system. The system comprises a driver gas generator containing a conventional gas generating composition, a demand gas generator containing a body of gas generating material that will support combustion only when exposed to an external source of thermal energy and means for conducting the hot driver gas through passages in the gas demand composition to cause the demand gas composition to burn and produce additional quantities of gas. The flow of driver gas through the demand gas composition is regulated to vary the total gas output of the system. A pressure relief valve communicates with the output of the driver gas generator and is set at a predetermined pressure above the delivery pressure of the system to permit the system to idle when the control valve is shut and the flow of driver gas through the demand gas generator ceases.
