A curved-wing aircraft capable of spiral flight

Abstract

The invention discloses an arc-shaped wing aircraft capable of helical flying. The arc-shaped wing aircraft is characterized in that a central machine body adopts a single arc-shaped wing, the two sides of the arc-shaped wing aircraft are provided with straight wings, and the arc-shaped wing and the straight wings are in a straight flying wing layout in the horizontal direction; two flying modes such as helical-wing flying and straight-wing flying are adopted, the flying process can be controlled, and the short-distance taking off and landing can be achieved; in the taking-off and landing process, the helical type roll-flying action is finished by thrust differential of two ducted type engines, and the short-distance taking off and landing can be realized; the aircraft also has a normal fixed-wing rolling taking-off and landing; the aircraft flies in a helical manner, the arc-shaped wing and the straight wings are wholly regarded as single rotating wings, then the aircraft rotates around the axis of the helical-flying track, and lifting force capable of controlling the flying is provided for the aircraft; lifting ailerons are used for controlling the taking-off and landing of the aircraft, and the flying control in the horizontal direction is dependent on thrust differential and the lifting ailerons of the two groups of ducted type engines; the self stability of an inherent longitudinal and horizontal flying mode of the aircraft is realized by the arc-shaped wings and the dihedral straight wings.

Description

technical field [0001] The invention belongs to the field of aviation aircraft, and in particular relates to an arc-shaped wing aircraft capable of spiral flight. Background technique [0002] Aircraft design experts and researchers have been trying to design a vehicle that can take off and land short distances or vertically. At present, in practical applications, more mature short-distance or vertical take-off and landing aircraft include jet fighters similar to the F-35B "Lightning II", rotor helicopters similar to the UH-60 "Black Hawk" and V-22 A tilt-rotor aircraft like the Osprey. However, the F-35B aircraft has a conventional layout, mainly using a lift fan and a tail vectoring nozzle. The combination of the two generates an upward lift to achieve short-distance or vertical take-off and landing, but this implementation method consumes a lot of fuel and has high requirements on the engine. High, short-distance or vertical take-off and landing, the aircraft load is li...

Problems solved by technology

However, due to the soft-wing structure of the powered parachute, the flight process requires cumbersome processes such as straightening, inflating, switching and hanging the parafoil, and has high requirements for the wind field of the flying environment, and at the same time, it cannot take off in a spiral manner.
