摘　　要：阻力方向舵在无尾飞机上得到广泛的应用。以一种无尾飞机为例,讨论了阻力方向舵舵效的非线性、耦合性等基本特性,并说明了阻力方向舵张开后对飞机整体的影响。给出了阻力方向舵在无尾飞机航向增稳、空速控制、作为复合舵使用三个方面的应用实例和仿真结果,说明了阻力方向舵在无尾飞机飞行控制应用中存在的一些问题及其解决方法。A drag rudder is mostly used by tailless aircraft. Taking a tailless aircraft as an example, special characteristics of drag rudder efficiency, as nonlinearity and coupling, are discussed, which bring great challenges to flight control of tailless aircraft. Several examples as yaw stability augmentation and control, airspeed contrlol, and the usage of drag rudders as a composite control surface, are given to demonstrate the application of drag rudders to the control of tailless aircraft.
