Dynamics of Thin-Walled Elements of Rocket Engine under Impact Loads

摘要

Stress-strain analysis of a solid-propellant rocket engine is the subject of this study. A chosen material is selected in order to ensure its maximum strength at minimum weight of the engine. The airframe of the rocket engine is a thin-walled structure, which consists of cylindrical and spherical parts. The dynamic behavior analysis of this thin-walled structure under the action of impact loads is performed. The anisotropic material model and dynamic properties of the shell material are taken into consideration to solve the underlying problem.
