A missile diverter for controlling yaw and pitch includes several valve housings secured to an inside surface of a bridge or to a removable cylinder. The valve housings are secured in aligned positions by a layer of integral cured insulation. Gas valves are placed in the housings, and control lines are connected to the valves to allow remote control of the valves during flight. Cups loaded with propellant are secured in place near the valve housings. The valve housings, valves, cured insulation, and propellant cups are then overwrapped and secured within the outer shell of a missile. One method for making the missile diverter includes the step of applying a quantity of uncured insulation to an inside surface of a bridge and to an outside surface of each valve housing. Each valve housing is then positioned within the bridge and the insulation is cured to form an integral layer that holds the valve housings in their aligned positions and forms a hot gas seal.

Missile diverter integration method and system

A composite structure for rocket motors includes a longitudinal element of the composite structure, which is an assembly of segments of clamshell or barrel stave form. The element is held in place by a circumferential element, which is a composite overwrap of reinforcing fibers in a resin matrix. The matrix may be thermoplastic or thermosetting. The reinforcing fiber being high strength polyolefin thereby providing the rocket motor with insensitive munitions capability.

The invention is a propellant rocket motor case designed to meet insensitive munitions requirements comprising a propellant surrounded by a case having slots therein, and a wrapping around the case, the wrapping comprising a load bearing material which can withstand the hoop load on the case during normal firing of said rocket, the material also having the characteristic of losing strength or melting at undesired temperatures above normal storage temperatures, but below the autoignition temperature of said propellant, so that during undesired high storage temperatures the propellant will exhaust any subsequently generated gases, due to any subsequent propellant burning, by venting through said slots thereby avoiding any explosion or undesired operative one-way thrust.
