초록

A multi-pulse or multi-stage canister loaded solid propellant rocket motor. The canisters are prepared separately and loaded with solid propellant whereby the scrap rate may be reduced after which they are installed in a monolithic case which affords stiffness continuity over the length of the rocket motor to prevent guidance system upsetting free play. In order to reduce the complexity of installation of the membrane seal assembly for each pulse, the bulkhead therefor is manufactured integral with the case of the respective canister and becomes the forw...

청구항

A rocket motor comprising a monolithic elongate generally cylindrical case having means defining an aft aperture, at least two canisters each of which has an individual case and contains an individual grain of solid propellant material, said canisters disposed sequentially within said monolithic case in end to end relation with said canister cases attached to said monolithic case and to each other, means forming a closure to preclude flow communication between said canisters which includes means providing flow communication between said canisters when a ...
