Convertible-type aircraft, able to fly with the speed and the reduced operating costs of a fixed-wing aircraft and also to take-off/land vertically and hover/manoeuvre like an helicopter. The aircraft object of the invention comes in the form of a classical plane, with a fuselage (1), a fixed wing (2), an horizontal stabilizer (3) and a vertical fin (4), as well as one or several jet engines or turboprops (5) for propulsion and it comprises exposable rotors (6 and 7) installed inside the wing and possibly inside the horizontal stabilizer or the fuselage for lifting the aircraft for vertical take-off/landing and stationary flight. For the flight and the horizontal take-off/landing, the rotors are completely enclosed inside the wing and possibly inside the horizontal stabilizer or the fuselage.

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 fuselage; a propulsion system including a power source and a plurality of vertical thrust electric fans driven by the power source; and a wing extending from the fuselage. The plurality of vertical thrust electric fans are arranged along a length of the wing, the wing including a variable geometry assembly extending along the length of the wing and moveable between a forward thrust position and a vertical thrust position, the variable geometry assembly at least partially covering the plurality of vertical thrust electric fans when in the forward thrust position and at least partially exposing the plurality of vertical thrust electric fans when in the vertical thrust position.
