摘要

栅格舵从折叠到展开的过程中气动特性变化剧烈,对展开可靠性和导弹整体气动特性的影响都比较大。针对栅格舵这种复杂的构造形式,生成了带有棱柱层的非结构网格,再结合重叠网格技术对栅格舵导弹超声速绕流流场进行了数值模拟,计算结果与风洞试验结果吻合较好。在此基础上,对超声速下栅格舵动态展开过程的非定常流场进行了数值模拟,分析了栅格舵导弹动态气动特性的变化规律。

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
