An unmanned Wing In Ground Effect vessel (UWIG) for transporting the cargo with internal cargo hold contained in a seaworthy fuselage. The UWIG is autonomous or semi-autonomous. A pair of wings are attached to the fuselage. An on-board controller controls lift sufficient lift to travel in ground effect. The controller also controls UWIG surface maneuvering, taxiing and flying. The UWIG may be autonomous or semi-autonomous.

An inner middle rotor is rotated while an inner front rotor, an inner back rotor, and an outer rotor are not rotated. The inner middle rotor is surrounded by the inner front rotor, the inner back rotor, the outer rotor, and a fuselage. After rotating the inner middle rotor while not rotating the inner front rotor, the inner back rotor, and the outer rotor, the inner middle rotor, the inner front rotor, the inner back rotor, and the outer rotor are simultaneously rotated.

The disclosure provides a method of controlling the yaw of a fixed-wing UAV, with two propulsion propellers arranged parallel to each other and providing thrust for the UAV; A plurality of motors configured to drive the two propulsion propellers, wherein the thrust ratio provided by the two propulsion propellers is changed to generate asymmetric thrust which controls the active yaw of the UAV. The fixed-wing UAV provided by the disclosure improves the reliability of the thrust system and active yaw.

The disclosure provides a method of controlling the yaw of a fixed-wing UAV, with two traction propellers arranged parallel to each other and providing thrust for the UAV; A plurality of motors configured to drive the two traction propellers, wherein the thrust ratio provided by the two traction propellers is changed to generate asymmetric thrust which controls the active yaw of the UAV. The fixed-wing UAV provided by the disclosure improves the reliability of the thrust system and active yaw.

The disclosure provides a fixed-wing UAV, with two pull propellers or two push propellers arranged parallel to each other and providing thrust for the UAV. Wherein the thrust ratio provided by the two pull propellers or the two push propellers is changed to generate asymmetric thrust which controls the active yaw of the UAV.

A UAV with vertical takeoff and landing (VTOL) function having a plurality of lift propellers; a cabin engaged with a plurality of lift propellers; a water propulsion system engaged with the cabin to push the cabin in a forward direction when the cabin is at least partially immersed in water; at least one water inlet engaged with the water propulsion system; the cabin is a cargo hold or a passenger cabin. The UAV provided by the disclosure can realize vertical takeoff and landing in the water area, and fly, drive and navigate freely in the whole area.

The present application provides an unmanned aerial vehicle (UAV) assembly that plays a waterproof role and is configured to prevent a UAV part inside the assembly from contacting with water; and the assembly comprises a first component comprising at least one opening, and a second component configured to seal the opening of the first component so as to prevent water from pouring into the assembly from the opening. The present patent application extends the applicable range of ordinary UAV parts and enables the ordinary UAV parts to have the waterproof function.
