A VTOL (vertical take-off and landing) box-wing aerial vehicle with multirotor to provide VTOL flight includes a detachable cabin, centered fuselage, a pair of first wings extending outward from the upper portion of the fuselage and a pair of second wings extending outwardly and from the lower portion of the fuselage. The first and second wings are spaced apart longitudinally and vertically. The pylon joints the first wing and second wing at the tip to form the box-wing. The pylon includes heading control rudder. Secured to the wing or pylon or both wing and pylon, an overhead boom extending longitudinally to support a plurality of lift rotors or tiltable rotors for VTOL flight. Finally, the fuselage mounted push rotor or the overhead boom mounted tiltable rotors propel the vehicle forward to generate lift from the wings. Furthermore, the wings are equipped with elevators and ailerons for flight control.

A vertical takeoff and landing (VTOL) UAV having a UAV main body, two rear landing gears and two front landing gears; the two rear landing gears are fixedly connected to both sides of the rear bottom of the UAV main body, respectively; the two front landing gears are rotatably connected to both sides of the front bottom of the UAV main body, respectively. One end of the front landing gear away from the UAV main body is provided with a locating block. Rotating the front landing gear enables the locating block mounted on the front landing gear to get close to or away from the UAV main body.

A combination unmanned aerial vehicle (UAV) having a fixed wing UAV, a plurality of rotor UAVs, a first communication component and a plurality of second communication components. The first communication component is arranged on the fixed wing UAV, and the plurality of second communication components are correspondingly arranged on the plurality of rotor UAVs. The first communication component can communicate with the plurality of second communication components. When operating in long-distance and complex surrounding areas, it can fly to a designated position through the fixed wing UAV, and then release the plurality of rotor UAVs, which may carry out reconnaissance operations on one or more targets in one area at the same time, or operate on multiple targets in multiple areas, and transmit signal commands in real time through the first communication component and the second communication component.

An amphibious cargo carrying unmanned aerial vehicle (UAV) having a fuselage, two wings and two frames, in which a cargo hold is arranged at the lower end of the fuselage, the cargo hold is provided with a cargo chamber for cargo carrying, and the cargo hold can touch the water surface at the same time. When taking off or landing on the water surface, the hollow structure of the cargo chamber can provide additional buoyancy. The two wings are symmetrically arranged on both sides of the fuselage, the two frames are correspondingly arranged on the two wings, and the buoyancy parts can be detachably arranged on the two frames to provide buoyancy.

Embodiments include an aircraft comprising a fuselage; a wing connected to the fuselage; and first and second propulsion systems connected to the wing on opposite sides of the fuselage, wherein at least a portion of each of the first and second propulsion systems and at least a portion of the wing are tiltable between a first position in which the aircraft is in a hover mode and a second position in which the aircraft is in a cruise mode, wherein each of the propulsion systems includes pylon and a rotor assembly comprising a plurality of rotor blades.

A stowable lift rotor is coupled to an airframe of a VTOL aircraft. The VTOL aircraft is convertible between a VTOL flight mode and a forward flight mode. The stowable lift rotor includes a lift arm. The proximal end of the lift arm is coupled to the airframe of the VTOL aircraft. The stowable lift rotor also includes a rotor assembly including rotor blades coupled to the distal end of the lift arm. The lift arm is movable between various positions including an extended position in the VTOL flight mode, a stowed position in the forward flight mode and intermediate positions therebetween such that the distance between the rotor assembly and the airframe is greater in the extended position than in the stowed position.
