Title Design for Solid Pulse Rocket Motor

Abstract

Using solid pulse rocket motor for attitude control and ballistic correction is one of the most effective methods to improve the accuracy of mortars and rockets.Solid pulse rocket motor achieve attitude control and ballistic correction tasks perfectly, having great potential application value in the domains of spaceflight and military .This paper focuses on solid pulse rocket motor design taking the demand of Smart vehicle for high performance attitude and ballistic control motors.

According to great deal of relevant information at home and abroad, a specific motor structure with side nozzles is proposed according to the overall target and the arranging of solid pulse rocket motors is also designed. In this paper,the type and the size of the grains is designed, research of the ballistics of the combustion chamber using MATAB and a preliminary investigation of the side nozzles’performance with the help of FLUENT are included.

A check for the intensity of the combustion chamber of the solid pulse rocket motor while it is working1 and overloaded using ABAQUS is also done.

Keywords solid rocket motor，overall design，internal ballistic，side nozzles’ performance，intensity of the combustion chamber
