  • Method of loading a solid fuel rocket engine
    Patent number: 3931709
    Abstract: One or both ends of the body of a solid fuel rocket engine is provided with an internally thickened portion, which serves for the mechanical attachment of additional parts, that is the rocket head or the rocket base, to the end of the engine body, without any increase in the external cross-sectional dimension of the body. A block of propellant fuel is located within the engine body and has a portion of reduced cross-sectional dimensions corresponding to the internally thickened portion at the end of the engine body. The block is introduced into the body by cooling the former until its dimensions have shrunk sufficiently for it to be introduced.
