Abstrakt: In general sense, propulsion is an act of adjusting the motion of a body. Propulsion mechanisms give the force that moves bodies that are at rest initially. A rocket motor is a classic example of a typical power transmitting system. The chemical energy within the fuel is converted to thermal energy by a combustion method. High pressure and extreme temperature gases are extended through a convergent-divergent nozzle. This process, the internal energy of the gas is changed over into motor power of the fumes stream, and a push is created by the weight level on the surface to which the gas is exposed. Motor case configuration assumes a significant job since it shields the engine from outside components, and it must withstand high temperature and weight created by the engine. The plan and development of the solid rocket motor equipment involve considering wide range of stresses exerted on the motor interior and exterior due to pressure and thermal loads. In this paper, we are going to design a solid-propellant rocket motor casing to a particular thickness that can withstand the required operating pressure developed in the casing and the pressure oscillations developed in the motor case because of the forces developed inside the combustion chamber. The modeling of the motor casing is carried out using Creo Parametric. The structural analysis of the obtained design is done using ANSYS workbench. The results of the stresses in static structural are obtained with the analysis. [ABSTRACT FROM AUTHOR]
