摘　　要：飞翼布局飞机取消了平尾和垂尾,构型的改变和阻力方向舵的使用使其呈现出与常规布局飞机不同的三轴稳定特性.以大展弦比飞翼布局飞机为研究对象,开展了其三轴静、动稳定特性的研究;通过与常规大展弦比飞机进行对比,揭示了飞翼构型参数、典型飞行状态对其稳定性的影响规律;分析了阻力方向舵的偏转对此类飞机稳定性的影响.研究结果表明,大展弦比飞翼布局飞机的本体稳定性存在诸多的不足.A flying wing cancels horizontal and vertical tails,but the changes of configuration and the use of drag rudder make it differ much from the conventional configuration aircraft in three-axis stability characteristics.The aircraft chosen for the study is a flying wing with high aspect ratio.Its three-axis static and dynamic stability characteristics are studied.Comparing with the conventional configuration aircraft with high aspect ratio,the effects of configuration parameters and typical flight condition on the stabilities of the flying wing are discussed.The impact of the drag rudder on the stabilities of such aircraft types is also analyzed.Results show that there are many deficiencies in the inherent three-axis stabilities of the high aspect ratio flying wing.
