The present invention relates to the technical field of UAV (unmanned aerial vehicle), and more particularly to a UAV with linkage foldable arms, which includes a linkage mechanism, a fuselage body and multiple aircraft arms. The multiple aircraft arms are connected with each other through the linkage mechanism and are connected with the fuselage body; a locating part is located in a middle of the fuselage body; the locating part comprises a positioning structure, a fixed structure which plays a limit role is located on one of the multiple aircraft arms, the fixed structure is buckled with the positioning structure. When the aircraft arms are unfolded or folded, only one aircraft arm needs to be operated to drive other aircraft arms to move under the action of the linkage mechanism, so that multiple folding steps are simplified into a folding process, which is convenient in operation and strong in practicability.

Transformable unmanned vehicles and related methods are disclosed. An example vehicle includes a body having, a first cap, a second cap spaced from the first cap, and a plurality of segments radially spaced relative to a longitudinal axis of the body. The segments are movable relative to the first cap and the second cap. The vehicle includes a payload supported by the first cap. An actuation system moves the segments relative to the first cap and the second cap to transform the body between a first configuration and a second configuration different than the first configuration.

Embodiments of the present invention disclose an arm and an unmanned aerial vehicle (UAV). The arm is mounted on a movable object and is in contact with an outline of the movable object after being folded. The UAV includes a vehicle body, the arm connected to the vehicle body and a power device disposed on the arm. The arm is in contact with an outline of the vehicle body after being folded. According to the technical solutions, the arm provided in the embodiments of the present invention can be in contact with the outline of the movable object after being folded, so that the structure of the movable object to which the arm is applied is more compact.

A locking pin associated with one of a fixed wing and a wing tip device, and a bush associated with the other of the fixed wing and wing tip device, the bush configured to receive the locking pin. The bush is located within a bush housing arranged to allow relative movement of the bush in the direction of a longitudinal axis of the locking pin when the locking pin is received within the bush.

To provide an unmanned aerial vehicle that is optimized for freight purposes and that efficiently performs loading and unloading of freight and efficiently performs airframe management. This object is solved by an unmanned aerial vehicle that includes a plurality of propellers. An airframe of the unmanned aerial vehicle includes: a body having a freight chamber that is a hollow portion and that is integral with the body; and a plurality of arms supporting each of the plurality of propellers. A combination of the one arm and the one propeller or plurality of propellers supported by the one arm constitute a retractable propeller. The retractable propeller is partially or entirely storable in the freight chamber.

An unmanned aerial vehicle includes a plurality of propellers and an airframe. The airframe includes a body having a hollow portion, and a plurality of through holes connected to the hollow portion and formed on an outer peripheral surface of the body. The airframe also includes a plurality of arms supporting the plurality of propellers, and each arm of the plurality of arms includes a base end portion disposed at a body side in a longitudinal direction of the respective arm. The base end portion is inserted in a corresponding through hole of the plurality of through holes and supported by the body. Each arm of the plurality of arms is configured to be stored in the hollow portion of the body by being retracted into the body via the through hole, and expanded out of the body by being pulled out of the body via the through hole.

A frame and a multi-rotor unmanned aerial vehicle are provided. The frame includes a triangular arm and a center frame. An apex of the triangular arm is hinged with the center frame. The triangular arm includes a first arm, a second arm, and a telescopic arm. The first arm, the second arm, and the telescopic arm are hinged together to form a triangle. When the telescopic arm moves from an extended state to a retracted state, the triangular arm is folded toward a direction close the center frame.

An aerial imaging aircraft operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft includes an airframe having first and second wings with first and second pylons coupled therebetween. The airframe has a longitudinal axis and a lateral axis in the VTOL orientation. A two-dimensional distributed thrust array is coupled to the airframe. The thrust array includes a plurality of propulsion assemblies each operable for variable speed and omnidirectional thrust vectoring. A payload is coupled to the airframe and includes an aerial imaging module. A flight control system is operable to independently control the speed and thrust vector of each of the propulsion assemblies such that in a level or inclined flight attitude, the flight control system is operable to maintain the orientation of the aerial imaging module toward a focal point of a ground object while translating the aircraft.

An aerial vehicle includes a deformable frame. The deformable frame includes a center frame and two arm assemblies. The two arm assemblies are disposed at two sides of the center frame respectively, and are rotatably connected to the center frame, to enable the deformable frame to switch between an unfolded state and a folded state. Each arm assembly includes a deformable rod and a cross rod. The deformable rod includes a first end rotatably connected to the center frame, and a second end rotatably connected to the cross rod and having a height larger than the first end. In the unfolded state, second ends of the deformable rods in the two arm assemblies are away from the center frame. In the folded state, the deformable rods in the two arm assemblies are stacked above the center frame. The aerial vehicle further includes a loading mounted on the center frame.

A parasite aircraft for airborne deployment and retrieve includes a wing; a fuselage rotatably mounted to the wing; a dock disposed on top of the fuselage and configured to receive a maneuverable capture device of a carrier aircraft; a pair of tail members extending from the fuselage; and a plurality of landing gear mounted to the wing. A method of preparing a parasite aircraft for flight includes unfolding an end portion of a wing; unfolding an end portion of a tail member of the parasite aircraft; and rotating a fuselage of the parasite aircraft so that the fuselage is perpendicular to the wing. A method of preparing a parasite aircraft for storage includes rotating a fuselage of the parasite aircraft to be parallel with a wing of the parasite aircraft; folding an end portion of the wing; and folding an end portion of a tail member of the parasite aircraft.
