摘　　要：1.引言 近代战斗机和战术导弹,为获得高机动性能,一般均在大迎用下飞行.众所周知弹翼涡的破裂对大迎角导弹气动特性有着重要影响.The variation of the wing vortex breakdown vs. the angle of attack for a missle with a cruciform set of wings was investigated through experiments. The tests was carried out by conducting the flow pattern visualization in the water channel at BUAA. The model had two nose shapes-pointed and blunted nose. The wing was set at fore or aft location along the axis of the body. The experimental results indicate that for the configuration with the same nose, the location of the vortex breakdown for the 'wing with aft location is closer to the wing trailing edge than that of the wing with fore location. While for the configuration with wing at aft location, the wing vortex breakdown for the blunt nose is delayed comparing to that for the pointed nose.
