Embodiment Construction

[0027] A deformable wing, comprising a wing leading edge 1 and a wing trailing edge 2; between the wing leading edge 1 and the wing trailing edge 2, a sliding assembly 3 is used to realize expansion and contraction; the wing leading edge A foldable skin 4 is connected between 1 and the trailing edge 2 of the wing.

[0028] Described slide assembly 3 comprises the slide bar 10 that is located at wing leading edge 1 inside and slide rail combination, and described slide rail has a plurality of and is arranged in parallel with each other, and each slide rail is all provided with a slide bar 10; The other end of bar 10 all links to each other with wing trailing edge 2 front ends; At least one slide bar (0 is provided with rack and is equipped with the gear that meshes with rack; 1 internal micro motor; the micro motor drives the rack through the gear and then drives all the slide bars 10 to slide along their respective slide rails, so as to realize the expansion and contraction of...

Abstract

The invention relates to an aircraft wing, in particular to a deformable wing and a vertical take-off and landing aircraft using the wing. It solves the technical problem that the current vertical take-off and landing aircraft has a large wingspan and is easily affected by wind and unstable attitude in the vertical take-off and landing state. A vertical take-off and landing aircraft adopts a deformable wing as an integral fuselage, and the deformable wing includes a leading edge of a wing and a trailing edge of a wing; The components realize expansion and contraction; a foldable skin is connected between the leading edge of the wing and the trailing edge of the wing. The chord length of the deformed wing designed by the invention can be stretched and changed to change the size of the wing, and the area of ​​the wing can be changed; at the same time, the advantages of the fixed-wing aircraft and the multi-rotor aircraft are combined, and the function of arbitrarily switching between two flight modes of the same aircraft is realized.

Description

technical field [0001] The invention relates to an aircraft wing, in particular to a deformable wing and a vertical take-off and landing aircraft using the wing. Background technique [0002] Google's "Project Wing" prototype is a 1.5-meter-wide monoplane drone that can take off vertically and turn horizontal to fly. But when this aircraft flies with vertical state, wide wing area is easily affected by wind force, makes the stability when flying in vertical state, operability is bad. [0003] In the prior art, there is a method of changing the area of ​​the wing by inflation. Conventional inflatable wings have disadvantages such as poor structural stiffness and strength performance: when the wing adopts a large aspect ratio configuration, under the condition of large wing load, the wing deformation is serious due to the poor stiffness of the inflated wing, which greatly reduces the aerodynamic force. Efficiency and operational capability, and in order to pursue better stru...
