Example Embodiment

[0027] A deformable wing includes a wing leading edge 1 and a wing trailing edge 2; the wing leading edge 1 and the wing trailing edge 2 are expanded and contracted by a sliding assembly 3; the wing leading edge A foldable skin 4 is connected between 1 and the trailing edge 2 of the wing.

[0028] The sliding assembly 3 includes a sliding rod 10 and a sliding rail combination arranged inside the leading edge 1 of the wing. The sliding rails are arranged in parallel with each other, and each sliding rail is provided with a sliding rod 10; The other end of the rod 10 is connected to the front end of the trailing edge 2 of the wing; at least one sliding rod (0) is provided with a rack and equipped with gears meshing with the rack; the sliding assembly also includes 1 Internal micro motor; the micro motor drives the rack and pinion through gears to drive all the slide bars 10 to slide along their respective slide rails to achieve the expansion and contraction of the leading and trail...

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...
