Abstract:
1. An aircraft to achieve vertical take-off and landing (VTOL), the aircraft comprising: a jet engine with a downward deflectable propelling nozzle; an auxiliary power unit with a downward deflectable propelling nozzle; and a transformable wing comprising a fixed wing, a hydraulic sleeve, an air intake duct including an upper wall and a lower wall, a thin wing connected to the hydraulic sleeve and located between the upper and lower walls, a sliding wing, leading edge flaps, trailing edge flaps, an aileron, and a hinge, the transformable wing being configured, during vertical takeoff/landing, to transform such that a leading end to an air intake duct in a vertical direction is formed on the fixed wing, and the air intake duct is formed internally in and along a direction of the wingspan of the fixed wing to cause air taken in by the jet engine to flow, in a common direction, over upper and lower surfaces of the thin wing, a chord line of the thin wing being in the direction of the wingspan of the fixed wing, thereby generating lift for vertical take-off/landing, the transformable wing being configured, during forward flight, to restore a normal shape in order to reduce drag, the aircraft further including an assembly, which is an integral and inseparable part of the transformable wing, the assemble including an extended section of air intake duct, an openable and closable leading end to air intake duct in horizontal direction, and an openable and closable leading end to air intake duct in vertical direction.
