摘　　要：给出了在一种飞翼布局上多种气动措施对该布局航向特性影响的探索性研究,包括机头安装不对称边条,机翼前缘不对称安装绕流物以及机头不同位置微量吹气等。结果表明这些措施都能提供航向控制力矩,其中头部边条的作用最明显,头部不对称切向吹气提供的航向控制能力也能达到常规方向舵的水平。An exploratory investigation to the effects of some aerodynamic devices including asymmetric nose strake, asymmetric spoiler on leading edge of wing, and weak blowing on nose of fuselage,is given in the paper.The results shown that these devices all can provide moment for yawing control, especially the nose strake with appreciable effects, and the yawing control capability provided by asymmetric nose blowing in tangent direction can reach the level provided by convention rudder.
