angle of rudder deflection 方向舵偏转角
moment due to rudder deflection 偏转方向舵产生的力矩
moment coefficient to rudder deflection 偏转方相舵形成的力矩系数
Moreover, the rudder deflection angle matches reasonably with the balance angle of attack, so the ERGM has super glide ability.
舵偏角与平衡攻角匹配合理，有较高的滑翔增程能力；
The high-aspect-ratio flying wing eliminates vertical tail and conventional rudder, and uses instead a split drag rudder with large deflection as its directional control surface.
大展弦比飞翼布局飞机取消了垂尾和常规方向舵，通常采用大偏角的开裂式方向舵作为偏航操纵面。
