| 摘 要： | 针对正常式布局导弹外形，在保证其它气动性能不变的情况下，提出了一种减小超声速大攻角情况下斜吹力矩的边条布局，使该类导弹在大攻角下实现极高机动能力成为可能。以计算流体力学为主要手段，分析了此种边条布局减小斜吹力矩的作用原理，即边条对翼面局部流场的干扰影响了翼面压力的分布与大小，从而使得翼面的滚动力矩降低。

| Abstract: | A finned missile configuration to reduce the rolling moment in oblique flows at supersonic speed and high angle of attack is presented under the precondition of no changes in other aerodynamic performances,making the high maneuverability of this kind of missile possible at the high angle of attack.With the CFD method,the mechanism of reducing the rolling moment in oblique flows by means of the finned configuration is analyzed.The results show that the interference of the fins on changes the local flow field... |
