Abstract : When considering the initial design of the case or load bearing components for a solid propellant rocket motor a number of possible solutions may be apparent and many factors need consideration before the design of the individual components can be finalised. The process of optimisation involves consideration of material properties, methods of manufacture, inspection and proof as well as interactions with other rocket motor and missile components. The various factors are considered and indications are given of the interactions to be taken into account. This paper concentrates primarily on the design of metallic motor cases. Both homogeneous and nonhomogeneous body structures are considered, the latter being fibre overwound metallic and strip laminates. A relatively recent requirements is that for insensitive munitions and this factor is also discussed relative to body construction.
