Abstract
A control system for supplying uncured propellant into the combustion char of a missile. The system includes a moving injector cooperating with a pressurized putty-like uncured propellant. This combination provides the missile with a propulsion system having rapid wide range throttling, shut off and restart capabilities.
Claims1
A control system for supplying uncured putty-like propellant into a missile combustion chamber comprising:
- a propellant storage chamber;
- means for pressurizing propellant in said chamber;
- said pressurizing means including a warm gas generator, an igniter for igniting said generator and a roll seal which acts on said propellant when actuated by gas from said generator;
- a movable injector;
- a metal web supporting said movable injector;
- said web being provided with propellant discharge openings therein;
- a seat provided with a rubber flow seal;
- said web being disposed between said propellant storage chamber and said combustion chamber for cooperation with said rubber flow seal to control the propellant flow between the injector and the seat;
- said injector and said seat provided with a double angle therebetween to serve as a radiation shield;
- an annular piston connected to said metal web and a hydraulic system to actuate said piston to move said web and injector in a forward or rearward direction.
