ABSTRACT:
A 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, of a multi-pulse rocket motor the bulkhead therefor is manufactured integral with the case of the respective canister and becomes the forward closure thereof. For a multi-stage rocket motor, the monolithic case may be stepped and tapered, and the stages severable therefrom as they burn out by primer cord. A tight fit may be provided between a canister and the monolithic case by constructing the canister case to form a tight fit with the monolithic case at ambient temperature, lowering the temperature of the canister to a temperature which permits its insertion in the monolithic case, and allowing the canister to warm to ambient temperature.
