导弹“×”翼状态翼面流动分析

FLOW ANALYSES ON WINGS OF A MISSILE AT " × " SITUATION

本文从流态结果的研究出发提出对导弹“×”翼状态翼面流动的分析方法,指出有迎角和侧滑角情况下四片翼面各不相同的有效迎角和前缘有效后掠角对于翼面流动以及气动力的影响。本文的分析方法对于分析“×”翼在有迎角和侧滑角情况下的操纵面效能及其导弹的制导有一定的帮助,也可以为有关计算模型的建立提供一些物理依据。

An analytical method is described for the fluid flows of the cross wings of a missile at angles of attack and yaws according to the analyses of the results for the flow visualization studies in a water channel. It is noted that there are very different effective angles of attack and effective swept angles of leading edges for the four cross wings and then different effects on the fluid flows and their aerodynamics. It is supposed to be helpful for analysing the efficiency of control surfaces of the cross wings and therefore the guide of the missile. Also it is useful setting the computational model of a missile with cross wings.
