| 摘 要： | 本文讨论了鸭式布局导弹滚动力矩特性。由于鸭式舵面偏转在稳定尾翼附近诱导一个非对称下洗流场。尾翼上产生反滚力矩。通过理论分析,提出一种新的尾翼布局形式,经风洞实验证明了新布局形式明显地减少了反滚力矩,提高了鸭式副翼的效率,特别是消除了零攻角附近的副翼反效现象,从而为鸭式布局导弹外形设计提出一个有利气动外形。

| Abstract: | In this paper the rolling moment characteristics of canard missiles are studied extensively.As a result of canard fin deflections an asymmetric downwash flow field near the tail fins is induced,producing a so called "reversed" rolling moment,i.e,,a moment in opposite sense to that produced by canard fin deflections.With the aid of theoretical analysis,a new type of tail configuration is suggested.Wind tunnel experiments show that the new configuration has reduced the reversed rolling moment and,especially,eliminated the aileron reversal phenomenon near zero angle of attack. |
