Numerical Simulation on Aerodynamic Characteristic of an Air-to-Air Missile

In order to compute the aerodynamic characteristic of an Air-to-air Missile in different mach numbers and different attack angles were carried though making use of CFD software Fluent, the 3-D Reynolds-averaged incompressible Navier-Stokes equations were solved numerically by using a finite volume method. The movement trend of pitching moment coefficient, lift coefficient, and drag coefficient with variety of mach numbers and attack angles were gained, meanwhile, distributing trends of pressure, temperature and airflow velocity were also obtained. The results indicated that the basis and references could be offered by numerical computation results for shape design of missile and definite preponderances were showed than traditionary numerical computation methods.
