Abstract : A variable energy missile eject system in which the rate at which cooling water is injected into the hot gas flow from a solid propellant rocket motor may be varied to optimize the eject energy according to launch depth. A first set of injection apertures through which water is always injected provides the necessary cooling and establishes the minimum rate of water injection (maximum launch energy). Additional sets of injection apertures having varying numbers of apertures are individually controlled to allow the water injection rate to be increased by increasing the number of injection apertures.
