Abstract : In a recent development in jet motors, a motor is launched and accelerated by a rocket propellant to a desired speed at which the propellant becomes expended and the motor is then sustained in speed as a ram jet motor, the same combustion chamber being employed in both modes of operation. This has required exhaust or thrust nozzles of different cross sectional areas due to the difference of pressure, volume and velocity of the exhaust gases while operating under each mode. One manner of attaining this end is to provide a rocket nozzle which telescopes within the ram jet nozzle and is ejected at rocket burn out, providing a larger nozzle for ram jet operation. The patent describes such a system.
