A morphing wing includes a pantograph mechanism capable of being extended and contracted in a predetermined direction, a plurality of flight feathers attached to the pantograph mechanism, connection members configured to connect flight feathers adjacent to each other among the plurality of flight feathers, a first rotating mechanism configured to rotate the pantograph mechanism around one axis of a plane that intersects the direction, and a second rotating mechanism configured to rotate the pantograph mechanism around another axis of the plane. Each of the plurality of flight feathers is configured so that an angle formed by adjacent flight feathers connected via the connection members increases as the pantograph mechanism extends.

A manned/unmanned aerial vehicle adapted for vertical takeoff and landing using the same set of engines for takeoff and landing as well as for forward flight. An aerial vehicle which is adapted to takeoff with the wings in a vertical as opposed to horizontal flight attitude which takes off in this vertical attitude and then transitions to a horizontal flight path. A tailless airplane which uses a control system that takes inputs for a traditional tailed airplane and translates those inputs to provide control utilizing non-traditional control methods.

A vehicle comprising a morphing wing and a body is disclosed. The aircraft is configured to transform from a first configuration into a second configuration for ascent or descent of the aircraft. The drag force and lift force on the aircraft in the second configuration are less than in the first configuration. Transforming from the first to the second configuration comprises: contracting the wing within a geometric plane defined by the wing, and rotating the outer edge of the wing downwards, out of the geometric plane.

A multirotor aircraft that comprises a body, at least three motors and at least one wing that is connected to the body. The wing is designed to be folded and unfolded during flight of the multirotor aircraft and designed to change during the flight a low-drag creation position to a lift creation position, and vice versa. At least one motor has a greater motor power than another motor and the distance from the strong motor to the center of gravity of the multirotor aircraft is shorter than the distance from the another motor to the center of gravity. The wing is positioned in the geometric area between the motors.

Adaptive wing systems and aircraft. A variable-span wing for aircraft comprises a fixed-section (1) with skin (118) that forms a lift-generating wing surface, and further comprises a top and a bottom moveable section (2) that are vertically offset from one-another and which translate in substantially lateral directions into and out of the fixed-section (1) through fixed-section tip-openings (126). The moveable sections (2) overlap inside of the fixed-section (1) when fully retracted. The wing also comprises at least two tracks (310,316) and track-mating parts (320). The track-mating parts (320) are attached near the roots of the moveable sections (2) and translate along the tracks (310,316) to guide the moveable sections (2). A non-overlapped wing with motors (331) that translate with the moveable sections (2) and which have attached gear heads (332). A rack (341) is located within the fixed section (1). Rotation of the gear heads (332) against the rack (341) causes the moveable sections (2) to translate. A non-overlapped wing having two disc-like elements (334) and a loop-like element (343) around the disc-like elements (334). Rotation of a disc-like element (334) causes the loop-like element (343) to push-and-pull the moveable sections (2) in opposing directions into and out of the fixed section (1). An aircraft utilizing the first-described wing having a propulsion system (8) and a set of elevons (5).

An aircraft wing section assembly is disclosed having a structural spine, a movement mechanism including a support rod extending through the structural spine, a first lever, for connection to and for moving a first moveable control surface, pivotally mounted to the support rod, a second similar lever for connection to and for moving a second moveable control surface, and a connection mechanism for connecting the first and second levers such that pivotal movement of the first lever causes pivotal movement of the second lever, and an actuation mechanism for actuating pivotal movement of the first lever, such that, in use, when the actuation mechanism actuates pivotal movement of the first lever, the second lever also pivotally moves, thus causing movement of both the first and second moveable control surfaces. Also disclosed is an aircraft wing assembly, an aircraft and a method of operating an aircraft.

A vertical take-off and landing (VTOL) unmanned aerial vehicle having a foldable fixed wing and a twin-ducted fan power system (7) arranged at a tail portion of a fuselage in a transverse and tail propulsion arrangement provides lift for vertical take-off and landing and propulsion for horizontal flight. By means of deflection of a control servo plane arranged at a duct exit, a vectored thrust is provided to enable a fast attitude change. When the aerial vehicle takes off and lands vertically/flies at a low speed, the wing is folded to reduce the frontal area exposure to crosswind. When the aerial vehicle is flying horizontally, the wing is expanded to obtain larger lift. A Coanda effect is created at a trailing edge of the wing by suction of the duct to improve performance.
