A heavily insulated, hydraulically actuated, compound poppet valve is positioned in a main gas stream between a gas generator and a rocket motor so that the gases must flow around it and be diffused thereby. It is also capable of selectively valving a variety of ports from the gas generator into the rocket motor to achieve desired ignition effects; and it can turn off flow completely between the two motors and prevent excessive heat from the rocket motor from entering the gas generator.
A combined diffuser, thermal barrier, and interchamber valve for metering gases as desired from a gas generator, having an apertured aft closure, into a solid propellant rocket motor, having an apertured forward closure, comprising: a pipe having one closed end with a central orifice and a plurality of canted, radially-oriented orifices in the closed end, the orifices also being equipped with valve seats on their inlet ends; a double acting, hydraulic actuator positioned centrally in the pipe and having a piston with an actuation arm attached thereto; a ...
