| Abstract: | A numerical simulation of aerodynamic characteristics of shell with angle of attack at the shell head is given by using Compational Fluids Dynamics(CFD) software. The aerodynamic dynamical software of the flow field around the shell with angle of attack at the shell head is analysed. The result characterictic showed that the considerable control force and moment was produced by shell head having an angle relative to body. This paper provides the numerical calculation method of developing self-adapt shell. |
