abstract |
An orificed pressure vessel has a combustion chamber adjacent the orifice and a propellant charge in the remainder thereof comprising wafer segments of propellant separated from each other by combustion barriers; an electric igniter adjacent each propellant wafer has a thermally operated, normally open switch, so that the circuit is closed for each igniter as the adjacent wafer is burned; a pressure transducer in communication with the combustion chamber operates a master switch connected in series with the igniters and an electrical energy source to close the entire circuit or open it in response to a predetermined maximum and minimum chamber pressure; and valve means on the orifice permits withdrawal of gases from the combustion chamber for use as desired. Optional equipment includes a pressure relief valve in the combustion chamber and a capacitor connected in parallel between the energy source and the igniters. |
