Abstract

To analyze the aerodynamic characteristics of internally carried air-launched launch vehicle's body after separating from aerial carrier, the 3-D turbulence field of launch vehicle was simulated and then numerical analysis was made to predict the influences of the angle of attack on launch vehicle. Aerodynamic parameters, pressure cloud maps of rocker's body and formation of flow flied with different angle of attack could be got. Force and moment coefficient curves were protracted, characteristics of flow field that disturbed by the rocket were determined. All the results show the effect of the aerodynamic characteristics of vehicle on air-launched system design.

Key words： air launch; CFD; launch vehicle; aerodynamic characteristics; flow field
