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 solid propellant dual pulse rocket motor has a pressure vessel containing two pulse grains separated by a barrier insulator. An igniter assembly disposed at a fore end of the pressure vessel selectively ignites a first pulse grain from a central channel within the grain. The igniter assembly also ignites a second pulse grain by ejecting hot combustion gases onto the fore end of the grain. Using such an ignition arrangement, a dual pulse rocket motor may be constructed using standard off-the-shelf ignition components.
