Abstract

Rapid variation of aerodynamic characteristics in deployment makes great impact on unfolding reliability and aerodynamic characteristics of grid fin missile. In this paper, a high quality unstructured grid with prismatic layers generated for such a complex geometry, and chimera grid was applied to combine computation domain around body and grid fins, then N-S equations were solved numerically to simulate supersonic flow field of grid fin missile. The simulation results show excellent agreement with the experiment data. Based on grid strategy and numerical method, the deployment process of grid fins was simulated under supersonic airflow, and dynamic aerodynamic characteristics were obtained.

Key words： grid fins; unstructured chimera grid; numerical simulation; deployment process
