The optimum design of dome shapes in helically wound composite pressure vessels which have been used as rocket motor cases, etc. is discussed, as a first step, based on the membrane stress theory. Some methods for determining the optimum dome shapes are proposed based on the two different kinds of criteria. One is based on the failure criteria of composite materials, and the simple formulae for determining the dome shapes are derived. The other is based on the performance factor for a rocket motor case, and the dome shape is analyzed by using mathematical optimization techniques. The dome shapes obtained are compared with the isotensoid dome shape derived from the netting analysis.
