摘　　要：格栅舵由小弦长的边框及其内部交叉放置的细薄格栅壁构成。作为一种新型的升力面,格栅舵具有失速攻角大、铰链力矩小等优点。本文采用非结构网格、利用商业软件CFX对亚/超声速条件下格栅舵导弹三维绕流流场进行了数值模拟,并与现有试验数据进行对比分析,符合程度较好。Grid fin is an unconventional lifting and control surface, which consists of an outer frame supporting an inner grid of intersecting planar surfaces of small chord. As a new type of lifting surface, the grid fin has the advantages of large stall angle and small hinge moment. Based on unstructured mesh, the three dimensions flow field of grid fin is simulated by applying the software CFX. The computation results are in good agreement with the experimental data.
