Some Progress in Development of Chinese Integrated Preliminary CAD Design of Solid Rocket Motors

Although there have come into existence many Chinese papers, we still deem it necessary to make a relatively deep study of the architecture of CAD (Computer Aided Design) system for integrated preliminary design of Solid Rocket Motors(SRM). Fig.1 shows the relatively detailed architecture of CAD system that we arrived at after careful study. Section 2 discusses the key technical measures that should be used in the development of our CAD system. We developed four modules: (1) overall interactive and optimization design of SRM, (2) grain design, (3) thermodynamic calculations, and (4) interior ballistic calculations. All four modules have already been welcomed by CAD designers as being quite useful.
