THROTTLED PROPULSION USING AN ELECTRICALLY CONTROLLED EXTINQUISHABLE SOLID PROPELLANT DUAL STAGE MOTOR

Utilizing newly developed solid propulsion technology developed at ET MATERIALS LLC a throttable controlled solid rocket motor will be develoed that incoporates variable thrust control without moving parts or varying the nozzle area. A dual mode grain incoporating ET MATERIALS controllable extiguishable solid propellant will be used to vary the pressure in the chamber containing a conventional AN high slope propellant. Various models will be studied to establish a thrust throttable range of 15:1 and determine the capability to provide for extiguishmens and reignition of the propellant grains. In addition, the capability of the controlled solid propellant to provide thrust control during the trnansient ignition phase will be established, thus providing for total thrush control management of the motor.
