The invention provides a rotor wing, and relates to the technical field of aircrafts, the rotor wing comprises a duct and at least two blades, one end of each blade is fixedly connected to the inner wall of the duct, each blade is arranged in the duct, the speed direction of the connection point of the joint of each blade and the duct is a first speed direction, and the speed direction of the connection point of each blade and the duct is a second speed direction. Each paddle extends from the inner wall of the duct to the direction away from the inner wall of the duct, and the included angle between the extending direction of each paddle and each first speed direction is an obtuse angle. The invention further provides an aircraft which is provided with at least one rotor wing. According to the rotor wing and the aircraft, the maximum forward flight speed can be increased to the maximum extent.
本发明提供了一种旋翼,涉及飞行器技术领域,包括涵道和至少两个桨叶,各桨叶的一端固定连接于涵道的内壁上且各桨叶设置于涵道的内部,各桨叶和涵道连接处的连接点的速度方向为第一速度方向,各桨叶由涵道的内壁向远离涵道内壁的方向延伸,且各桨叶的延伸方向与各第一速度方向之间的夹角为钝角。本发明还提供了一种飞行器,设置有至少一个上述的旋翼。本发明提供的旋翼和飞行器,能够最大限度地提升了最大前飞速度。
