    摘要： A propeller, a propeller kit, a power assembly, a power kit and an unmanned aerial vehicle (UAV). The propeller includes a hub and at least two blades connected to the hub. The hub is detachably mounted on a corresponding drive apparatus by a mounting member corresponding to the hub, so that the propeller is mounted on the corresponding drive apparatus. A surface, facing the mounting member, of the hub is provided with a first fitting portion. A surface, facing the hub, of the mounting member is provided with a second fitting portion corresponding to the first fitting portion. The first fitting portion matches the second fitting portion. In the foregoing manner, a user can be prevented from incorrectly mounting a forward propeller and a counter-rotating propeller during the use of a quick-detachable propeller in the embodiments of the present application.

    摘要： An aircraft wing and propulsion system includes a leading-edge device positioned at the leading edge of an aircraft wing and one or more propulsors affixed to the main body of the aircraft wing. The leading-edge device includes a moveable slat affixed to the aircraft wing with an extension mechanism such that the moveable slat is translatable between a closed position abutting a main body of the aircraft wing and an open position extended from the main body of the aircraft wing to form a gap. An associated method of operating the same during takeoff and landing includes extending the moveable slat to expose the propulsors on the aircraft wing and operating the propulsors during take-off or landing of the aircraft to provide increased power and lift for the aircraft.

    摘要： A ducted-rotor aircraft includes a fuselage and first and second ducts that are coupled to the fuselage. Each duct includes a duct ring, a rotor having a plurality of blades, a hub that positions the rotor such that the blades define a blade plane of rotation within the duct ring, and a plurality of stators that are coupled to the hub at respective locations aft of the blade plane of rotation. Each of the plurality of stators defines a leading edge that is slanted toward the blade plane of rotation. The leading edges of the stators are slanted to follow a contour defined by the blades. The leading edges may also be slanted to maintain a distance of at least one blade inboard chord length between the leading edges of the stators and respective trailing edges of the blades.
