The invention relates to a rotary wing aircraft (100) extending between a head (101) and a tail (102) along an associated rolling axis R. The rotary wing aircraft (100) comprises a main rotor (120); a propeller (130) configured at least to propel the rotary wing aircraft (100) in a forward flight condition, where the propeller (130) forms a circular propeller disc when rotated about an associated axis of rotation; and a shrouded duct (140) disposed in the tail (102) and forming an internal air duct at least partially housing the propeller (130), where the shrouded duct (140) includes a yaw and pitch stability enhancing unit to enhance yaw and pitch stability of the rotary wing aircraft (100) in a forward flight state.
本发明涉及一种旋转翼飞行器(100),其沿着关联的滚转轴线R在头部(101)与尾部(102)之间延伸。旋转翼飞行器(100)包括主旋翼(120);螺旋桨(130),其至少被构造为在向前飞行状态下推动旋转翼飞行器(100),其中螺旋桨(130)在围绕关联的旋转轴线旋转时形成圆形螺旋桨盘;以及带护罩的涵道(140),其设置在尾部(102)中并形成至少部分地容纳螺旋桨(130)的内部空气涵道,其中带护罩的涵道(140)包括偏航和俯仰稳定性增强单元,以在向前飞行状态下提高旋转翼飞行器(100)的偏航和俯仰稳定性。
