  • Integral solid booster and hybrid thrust sustaining system and projectile incorporating the same
    Patent number: 6125763
    Abstract: A rocket according to the invention includes a motor having a fuel chamber and an oxidizer tank, a nose portion provided forward of the motor, and a nozzle surrounded by fins provided aft of the motor. The fuel chamber is provided with a relatively central solid propellant, and a hybrid fuel surrounds the solid propellant. The oxidizer tank is filled with a reactant and coupled to the forward end of the fuel chamber. A pathway is provided between the tank and the fuel chamber for the passage of reactant therethrough. At least one of a valve and a barrier is coupled in the pathway to prevent passage of the reactant into the fuel chamber until after the solid propellant is at least partially consumed. After the solid propellant is at least partially consumed, the valve is opened and/or the barrier is removed to permit the passage of reactant into the fuel chamber.

  • Hybrid rocket system and integrated motor for use therein
    Patent number: 5893266
    Abstract: A hybrid rocket system and motor includes an oxidant tank communicating with a combustion chamber containing a solid fuel grain. The passage from the oxidant tank to the combustion chamber is obstructed by a fill tube which fills the oxidant tank with oxidant and pressurizes it. Once the tank is full, the fill tube is displaced from the tank-chamber passage to deliver oxidant to the grain and initiate the combustion process. The motor may be an integral part of the rocket, or it may be a modular, expendable or exchangeable cartridge-type device inserted into a reusable body.
