Folding type wing

Abstract

The invention relates to a folding type wing. The folding type wing is mainly formed by parts of a wing supporting framework, a sliding rail, skin-covered supporting ribs, a covering skin, a wing motion device and the like. By implementing a wing of which the wing supporting framework and a wing covering skin can be folded, closing and folding of the wing during stopping and storing of an aircraft can be realized, smaller space is occupied, the wing is unfolded after the aircraft takes off, then the area of the wing is enlarged, and the wing which can generate a lift force and bear the load is formed, so that the aircraft is supported to fly in the air; the folding type wing is mainly used for the aircraft flying at a lower speed, and belongs to the field of aviation.

Description

Technical field: [0001] The invention is a "folding wing", which is mainly composed of: wing support frame, slide rail, skin support rib, skin, wing action device and other parts, and is used for aircraft flying at a relatively low speed, belonging to Aviation sector. Background technique: [0002] The wing is an important part of an aviation vehicle. The main function of the wing is to generate lift to support the aircraft to fly in the air. The current wing is mainly composed of the wing inner support frame and the surface skin. The inner support frame consists of longitudinal and transverse Beams form a shape-fixed truss to maintain the shape of the wing section, support the surface skin, and withstand the aerodynamic load from the skin; the surface skin is used to maintain the shape of the wing and transmit the aerodynamic force of the wing to the wing support frame . [0003] The wing area of ​​existing fixed-wing aircraft is basically unchanged, and the shape of the ...

AI Technical Summary

Problems solved by technology

[0003] The wing area of ​​existing fixed-wing aircraft is basically unchanged, and the shape of the wing cannot be changed once it is determined. Therefore, when the fixed-wing aircraft is parked on the ground, it takes up a large space. In order to reduce the occupied space, the wings of some aircraft can be Partially folded, such as the carrier-based aircraft of an aircraft carrier; in order to reduce the space occupied by some small aircraft, the wings are rotated and the fuselage is overlapped, and then rotated and unfolded during flight, such as some small drones; but these methods are not The wing area cannot be changed, and it is also limited by many conditions, so it cannot be widely used

With the existing technology, it is impossible to make the fixed-wing aircraft: the wings can be folded and folded to reduce the occupied space when parked and stored, and the wings can be expanded under the flight state to expand the area so that the wings can generate enough lift to Support aircraft flying in the air
