  • Apparatus for expelling a payload from a warhead
    Patent number: 7168368
    Abstract: Apparatus within a warhead for expelling a payload from the rear of the warhead after a tail assembly has been removed. A separate thrust chamber within the warhead has an apertured thrust tube at one end which extends into the thrust chamber and a pusher plate at the other end for propelling the payload. The thrust chamber includes a propellant which, when ignited generates high pressure gas causing a rocket effect out the thrust tube to move the pusher plate and associated payload. The pusher plate may be disconnected from the thrust chamber to slow the expulsion process.
