Design and Analysis of Rocket Motor Casing by Using Fem Technique

This paper deals with the design of solid rocket mainly consists of determining the thickness of motor casing which includes the domes at head end, nozzle end and flange for bolted joints. Modeling of solid rocket motor components and its assembly is done in CATIAV5R19. Stress distributions are due to the effect of working stress developed in the components. The maximum working stress is compared with allowable yield stress of the material. Final conclusion brings out a well designed solid rocket motor for the effective storage of propellant for obtaining the required impulse. 2D Axi -Symmetric structural analysis for solid propellant rocket motor Casing is performed to determine the stress level of all components using ANSYS 12.0..
