An aircraft (1002) including a wing (1001), having a fixed wing (1005) with a wing tip device (1003) moveably mounted at the outer end thereof. The wing tip device (1003) is moveable between: a flight configuration; and a ground configuration about an axis of rotation. The wing tip device (1003) and the fixed wing (1005) meet along an interfacing cut line (1035). The interfacing cut line (1035) includes a curved section (1039) cent red on the axis of rotation (1011), the radius of the curved section constantly increasing as the cut line passes around the axis (for example a spiral shape).

An aircraft includes a wing and a rotor pod mounted to the wing. The rotor pod includes a body having a forward end and an aft end. A propeller is mounted to the body of the rotor pod at the forward end. A control surface is mounted to the body of the rotor pod between the forward and aft ends and extends outwardly from the body. The control surface is displaceable relative to the body between a first control configuration and a second control configuration to control an attitude of the aircraft. The control surface in the first control configuration is closer to the propeller than the control surface in the second control configuration.

A land-and-air vehicle configured to switch between a first form to be taken during ground traveling and a second form to be taken during flight includes a main body, a main wing unit, an operation unit, and a controller. The controller is configured to control, on the basis of an operation performed on the operation unit by an operator, a behavior of the land-and-air vehicle during the ground traveling and during the flight. The operation unit includes a handle and a step. The handle of the operation unit includes a throttle unit. The controller is configured to control, both during the ground traveling and during the flight, yawing of the land-and-air vehicle in response to an operation performed on the handle, and to control thrust for the land-and-air vehicle during the flight in response to an operation performed on the throttle unit.

An aircraft (1002) including a wing (1001), having a fixed wing (1005) with a wing tip device (1003) moveably mounted at the outer end thereof. The wing tip device (1003) is moveable between: a flight configuration; and a ground configuration. The wing tip device (1003) and the fixed wing (1005) are separated along an oblique primary cut plane (1013). The wing tip device (1003) and the fixed wing (1005) meet along an interfacing cut line (1035). The interfacing cut line (1035) includes a first length (1037) offset from the primary cut plane (1013) in a first direction; a second length (1041) that extends within a plane (P) containing the axis of rotation (1011), or a plane parallel thereto; and a transition section (1039) over which the interfacing cut line (1035) transitions from the first length to the second length. The second length may extend around the upper surface, around the leading edge and onto the lower surface.

An aircraft wing with a root, a tip, an inboard wing part, an outboard wing part, and a junction between the inboard wing part and the outboard wing part. The inboard wing part has anhedral and is swept back so that it extends downwardly and aft away from the root towards the junction. The outboard wing part has dihedral and is swept forward so that it extends upwardly and forward away from the junction towards the tip. An engine and landing gear are mounted at the junction. An aircraft with a pair of such wings has a W-shaped profile viewed from above, and an inverted gull-wing profile viewed from the front.

The present invention relates to an assembly of three wings joined with or without marginal plates, for aerial, water, land or space vehicles, to reduce induced drag and interference drag and provide greater manoeuvrability, independence in the fuselage design, optional installation of propulsion plant systems, an optional system of landing gears, increased maximum speed and reduced minimum speed, it being possible to reach zero speed or hover. The assembly also allows flight forwards, backwards, sideways, upwards and downwards or rotations about the axes of the vehicle.
