| 摘 要： | 开裂式方向舵是无尾飞翼布局飞机一种重要的阻力式偏航装置。本文在不同马赫数和舵偏下,通过风洞实验,深入研究了开裂式方向舵的作动对某无尾飞翼布局飞机气动特性的影响。研究结果表明开裂式方向舵是一种合理的偏航式操纵装置,能够在升力、侧力和俯仰力矩变化较小的条件下提供较大的偏航力矩,但也与滚转力矩存在一定程度的耦合。本文的研究为开裂式方向舵的工程化应用提供了一定的基础。

| Abstract: | Split-rudder is one of the important yaw control devices as a drag rudder.The effects of split-rudder deflection on certain tailless flying-wing aircraft was tested in wind tunnel at different Mach numbers and split-rudder deflections.The results show that split-rudder is a kind of reasonable yaw control device,which can produce considerable yawing moment with a little change in lift,side force and pitching moment.However,yawing moment produces coupled with rolling moment.Present investigation may provide some contributions for industry application of split-rudder. |
