Abstract:

Design considerations that influence the selection of materials for rocket-motor cases are discussed. The main intent is to clarify considerations of design for the benefit of the materials specialists in the aerospace industry and for the benefit of the materials industries which supply the aerospace industry. A brief discussion is given of types of missiles and mission profiles. This is followed by a discussion of the external and internal loads and environment to which the missile is subjected. The mechanical and thermal loads are reacted by the motor case acting as a structure hence, a discussion of stresses and other design factors is included. Next, structural safety and reliability are discussed from a design point of view. The following aspects of basic material behavior are discussed in relation to motor-case design requirements static mechanical behavior, fatigue behavior, thermal effects, and other environmental effects. In order to provide realistic criteria for materials selection, design for minimum weight is presented from the material- index point of view. Considerations not related directly to design, for example, producibility, cost, and corrosion resistance, are not included.
