Structural computer aided design for solid rocket motors with finocyl grain to sketch parametrically engineering drawings

In structural computer aided design for solid rocket motors with finocyl grain to sketch parametrically engineering drawing, 17 fundamental dimensions of motor structure were defined as variable parameters, their specific values can be input by means of man-machine interaction. A series of part drawings of components such as chamber grain and nozzle etc., and the general motor structure drawing can be sketched automatically.
