Numerical Analysis of the Influence of the Wake Flow Field in the Process of Parachute Deployment

Abstract

The wake flow field of the return cabin has an effect on the process of parachute deployment. In this paper CFD method is used to analyze the tail flow field and the flow field data are brought into the dynamic analysis by plane division and interpolation. The influence of the tail flow field on the deployment process is analyzed in the case of Mars and Earth. The result shows that the greater the separation speed or the angle of attack, the smaller the influence of tail flow field and it should be considered under low angle of attack in Mars environment. The influence is small enough that can be ignored in Earth environment.
