Nomographic Design Procedures for Fibre-Reinforced Metallic Rocket-Motor Cases,

Abstract

Nomographic design procedures are developed for a metallic cylinder (eg a rocket motor case) circumferentially reinforced with a pre-strained fibre overwind with viscoelastic properties. Techniques for calculating the pressure for first yield in the metallic case and the optimum winding conditions for both short- and long-times are presented, together with a technique for determining the maximum fibre stress. Design examples are presented with each nomogram in turn and the graphical results are compared with exact numerical results.
