In this article, it is attempted to present a study of the design, analysis and optimization of a projectile carrying a payload from the moment of loading until final release. Thus the study consists of the following:
First of all, the ballistics of the projectile must be solved and then diagrams of pressure-time and speed of the barrel and the maximum accelaration exerted on the projectile must be considered. The barrel speed is the required parameter in the trajectory section and to analyze the structural section the maximum accelaration is considered. Next, the structure of the projectile in the shell is considered in terms of stress based on the maximum speed gained from the internal ballistics. Also, the minimum thickness of the shell is assessed considering that the structure of the projectile should not fail. The next step it is attempted to strike a relative balance between the first two sections and finish the design cycle. Finally, the optimization of the design cycle in terms of the weight and thickness of the projectile is considered.
