摘　　要：采用基于结构重叠网格数值方法对大长细比导弹从平飞状态拉起至大攻角状态的非定常流场进行数值仿真,并将仿真结果与若干固定攻角状态的静态计算结果对比分析,发现两种情况下的结果存在明显差异,静态的横向结果偏大,动态的纵向结果偏大。结果表明在导弹的工程研制中,气动设计应充分考虑‘动静结合’的设计方式,以期达到最优效果。The numerical method based on overlapping structured grids is used to simulate unsteady flow of tactical missile with large slenderness ratio pulled up from a level flight to a high angle-of-attack (AOA). And the results are analyzed and compared with the static results of several selected AOA. The obvious difference is that the lateral value in static state is larger, while the longitudinal value in dynamic state is larger. The results show that in tactical engineering development, for the best effect,‘dynamic-static match’ mode should be fully considered in aerodynamic design.
