Abstract

In order to investigate aerodynamic characteristics of rocket at different angle of attack and mach number, the finite volume method was used to simulate the flow field of rocket in subsonic, transonic and supersonic flow. The drag coefficient, lift coefficient, pitching moment coefficient, lift-drag ratio and center of pressure with variation angles of attack, mach numbers were given. The results indicate that the drag coefficient, lift coefficient, pitching moment coefficient and center of pressure perform differently at small angles of attack and big angles of attack and they also act differently with variety of mach numbers. The maximum of lift-drag ratio will be gained at 22°~26°angle of attack for different mach number.

Key words： rocket; subsonic transonic and supersonic flow; aerodynamic characteristics; finite volume method
