An air mobility may include a wing portion extending from a fuselage of the air mobility; a folded portion provided at an edge portion of the wing portion, configured to extend from the wing portion to form a part of the wing portion during unfolding of the folded portion, and configured to move to overlap with the wing portion during folding of the folded portion, so that an area of air resistance in a vertical direction of the wing portion is reduced; an actuator connected to the folded portion and configured to provide power to the folded portion, so that the folded portion is unfolded or folded to the wing portion; and a controller connected to the actuator and configured to control the actuator, so that the folded portion is folded during vertical takeoff or landing of the fuselage, and configured to control the actuator to unfold the folded portion during cruising of the fuselage.

An aircraft (1) including a fixed wing (7) and a wing tip device (9) moveably mounted thereon. The wing tip device (9) is movable from a load-alleviating configuration to a flight configuration. The wing tip device includes an airflow channel (88) extending between respective apertures (83, 84) on the upper surface and lower surface of the wing tip device. The channel (88) is configurable between an open state in which air can flow through the channel and a closed state in which the airflow through the channel (88), via the apertures (83, 84), is blocked. The channel (88) is configured such that when the wing tip device (9) is in the load-alleviating configuration and the channel (88) is in the open state, the aerodynamic loading on the wing tip device in flight urges the wing tip device towards the flight configuration.

An aircraft with wing tip devices, for example, folding wing tips, is disclosed. The folding wing tip may have a flight configuration for use during flight, and a ground configuration for use in ground-based operations. The ground configuration creates a shorter wing span than when the aircraft is in the flight configuration. A hinge arrangement protrudes beyond an outer surface of the fixed wing and wing tip device. In order to reduce the aerodynamic effect of the protruding hinge a fairing may be provided. In the flight configuration the fairing comprises a rear portion with a concave surface, such that the fairing acts as a lift-generating surface when the aircraft is in flight.

A wing for an aircraft is disclosed having a fixed wing, a foldable wing tip portion, and a flight latch device for latching the foldable wing tip portion in the extended position, wherein the flight latch device includes a housing, a latch bolt linearly movable relative to the housing, and a motor for driving the latch bolt. The flight latch device includes a threaded shaft having an external thread and being mounted to the housing in a torque proof manner, the flight latch device includes a nut having an internal thread engaging the external thread of the shaft, so that the nut can rotate about the shaft along the external thread, the motor is arranged coaxially around the nut, wherein a rotor part is mounted to the nut in a torque proof manner, and wherein a stator part is rotatably connected to the rotor part and is connected to the housing by a first linear guide allowing linear movement and inhibiting rotation of the stator part.

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.

The ground configuration creates a shorter wing span than when the aircraft is in the flight configuration.

Disclosed is an aircraft with a super high aspect ratio based on self-unfolding folding wing technology, the aircraft including: an aircraft body; a fixed wing; and a movable wing assembly including a first movable wing and a second movable wing. When the aircraft takes off, the first movable wing and the second movable wing are in a folded position. The first movable wing and the second movable wing are deflected and moved to an unfolded position or a folded position by the aerodynamic force and moment generated by the deflection of aerodynamic control surfaces and the differential thrust and moment generated by a distributed propulsion system.

An aircraft wing having a fixed root part hingedly connected to a moveable tip part is disclosed. The tip part is configured to pivot relative to the root part about a substantially horizontal axis, between a load-alleviating configuration in which the tip part is oriented relative to the root part such that at least one of the upper and lower surface of the tip part is positioned away from the respective surface of the root part and a flight configuration in which the upper and lower surfaces of the tip part are continuations of the upper and lower surfaces of the root part. The shape of the tip part is controllably switchable between a cruise shape in which the tip part has positive camber and a recovery shape in which the tip part has negative camber.

An aircraft with wing tip devices, for example, folding wing tips, is disclosed.

In the flight configuration the fairing comprises a front portion blended into and extending rearwardly from the leading edge of the fixed wing and the wing tip device.

A simple, safe, and inexpensive flight control system in an aircraft. An anti-torque system for a rotary-wing aircraft has an airfoil with a first surface extending from a first trailing edge and a leading edge, and a second surface extending from a second trailing edge to join the first surface at the leading edge. The airfoil has a first moveable deflector panel pivotally coupled to the first trailing edge, and a second moveable deflector panel pivotally coupled to the second trailing edge. Means are provided to pivot the deflector panels in unison about their respective pivot axes to alter the direction of travel of the airflow downstream of the pivot axes over the surfaces of the deflector panels, thereby producing a lift in a direction perpendicular to the airflow to counteract the torque applied on the aircraft. The flight control system may be arranged within a fixed-wing aircraft.
