Embodiments provide a VTOL aircraft that includes a plurality of tilt propeller assemblies, each tilt propeller assembly coupled to a support structure and configured to transition between a vertical flight position and a forward flight position. Each tilt propeller assembly includes a propeller and a movable fairing disposed downstream of the propeller. The movable cowl is configured to extend along an axis of rotation of the propeller. When the tilt propeller assembly transitions between the vertical flight position and the forward flight position, the movable cowl is configured to rotate to extend in a minimum drag orientation parallel to a direction of total airflow across the tilt propeller assembly. The movable cowl has sufficient damping to prevent any oscillations due to propeller wake shedding and while maintaining the propeller aligned with the total flow at a minimum resistance orientation.
实施例提供了一种VTOL飞行器,其包括多个倾转螺旋桨组件,每个倾转螺旋桨组件联接到支撑结构并且构造成在垂直飞行位置和向前飞行位置之间过渡。每个倾转螺旋桨组件包括螺旋桨和设置在螺旋桨的下游的可移动整流罩。可移动整流罩构造成沿着螺旋桨的旋转轴线延伸。当倾转螺旋桨组件在垂直飞行位置和向前飞行位置之间过渡时,可移动整流罩构造成转动以平行于倾转螺旋桨组件上的总空气流的方向延伸成最小阻力取向。可移动整流罩具有足够的阻尼,以防止由于螺旋桨尾流脱落而造成的任何振荡,并且同时保持螺旋桨以最小阻力取向与总流对准。
