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 aircraft wings, in particular to deformable wings and a vertical take-off and landing aircraft using the wings. The technical problems that the wingspan area of a vertical take-off and landing aircraft is large at present, and the vertical take-off and landing aircraft is prone to being affected by wind power in the state of vertical take-off and landing so that the posture is unstable are solved. The deformable wings serve as an integrated airframe of the vertical take-off and landing aircraft. Each deformable wing comprises a wing leading edge and a wing trailing edge. Spreading and contracting between each wing leading edge and the corresponding wing trailing edge are achieved through a sliding assembly. A folding skin is connected between each wing leading edge and the corresponding wing trailing edge. According to the designed deformable wings, the size of the chord length can be expanded, contracted and changed, and the wing area is changed; meanwhile, the advantages of a fixed wing aircraft and the advantages of a multi-rotor-wing aircraft are combined, so that the function that the same aircraft can fly by arbitrarily switching two flight modes is achieved.

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 horizontally in flight. 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...
