Method of making solid propellant canister loaded rocket motor

A method of making a rocket motor comprising the steps of:

• a. providing a monolithic elongate generally cylindrical case having a forward end and an aft end;
• b. providing at least one canister having an individual case containing solid propellant material, the solid propellant material having a coaxial central aperture, and the canister being constructed to form a tight fit with the monolithic case at ambient temperature;
• c. lowering the temperature of the canister to a temperature which permits inserting of the canister in the monolithic case;
• d. inserting the canister in the monolithic case;
• e. allowing the canister to warm to ambient temperature thereby to expand and form a tight fit with the monolithic case;
• f. providing thrust nozzle means which engages the aft end of the monolithic case;
• and
• g. providing means within the central aperture of the solid propellant material for igniting the solid propellant material.

A method of making a rocket motor comprising the steps of:

• a. providing a monolithic elongate generally cylindrical case having a forward end and an aft end;
• b. providing at least two canisters each having an individual case and containing solid propellant material, the solid propellant material having a coaxial central aperture;
• c. inserting each of the canisters in the monolithic case with the canister cases in engagement therewith;
• d. attaching the individual canister cases to the monolithic case;
• and
• e. providing means within the central aperture of the solid propellant material for igniting the solid propellant material;
• and
• f. providing thrust nozzle means attached to the aft end of the monolithic case.
