Problems solved by technology

[0005] In the above-mentioned multi-rotor aircraft with fixed wings, the chord direction of the fixed wings is vertical during the actual lifting process, so that the lateral force area of ​​the fixed wings is relatively large, and the entire rotor aircraft is affected by the crosswind of the fixed wings during the vertical lifting process. Big, more difficult to control, and even cause flight accidents, more dangerous

Embodiment 1

[0041] figure 1 (a) indicates that the wing airbag 11 is in a retracted folded state, figure 1 (b) indicates that the wing airbag 11 is in the inflated and opened state, figure 1 (c) shows that the wing airbag 11 is fully opened.

[0042] Such as figure 1 As shown, the aircraft fixed wing in this embodiment comprises a rigid fixed wing leading edge 12, and the rear side of the fixed wing leading edge 12 is provided with a wing airbag 11 that can be retracted. In the airbag mounting bracket on the wing leading edge, the airbag mounting bracket can be integrally arranged with the fixed wing leading edge or fixedly assembled separately, and the expanded and opened wing airbag 11 forms the airbag wing part joined with the fixed wing leading edge. This kind of wing airbag 11 is a folding airbag, which realizes the expansion-retraction of the wing airbag by opening-folding. The connecting part 14 is not stretchable, while the flexible folding part 15 is stretchable.

Embodiment 2

[0048] Its difference with aircraft fixed-wing embodiment 1 mainly lies in: as figure 2 As shown, in aircraft fixed-wing embodiment 2, there are two wing airbags arranged along the span direction of the fixed wing, which are respectively an inner airbag 21 and an outer airbag 22. The two wing airbags are distributed independently of each other, and each wing airbag passes through The guiding structure 20 whose guiding direction is along the chord direction of the fixed wing performs an expansion-retraction action along the chord direction of the fixed wing. During specific implementation, slip rings 23 or bearings can be arranged on the wing airbags to be assembled correspondingly with the guide structure, so as to ensure normal sliding of the wing airbags along the guiding direction of the guide structure.

[0049] Moreover, in this embodiment, both the inner airbag 21 and the outer airbag 22 include a bladder made of elastic material, and the expansion degree of the bladder...

Embodiment 3

[0053] Its difference with aircraft fixed-wing embodiment 2 mainly lies in: as image 3 As shown, in the aircraft fixed wing embodiment 3, the two independent wing airbags arranged along the span direction of the fixed wing all perform expansion-retraction actions along the span direction of the fixed wing. In fact, there are corresponding A guiding structure for guiding the expansion and retraction of wing airbags, the guiding direction of the guiding structure is the span direction of the fixed wing.

[0054] In the present embodiment, the inside airbag 31 and the outside airbag 32 are included here, and the two airbags are distributed along the span direction of the fixed wing, and expand-retract along the span direction of the fixed wing. The balloon body can control the expansion degree of the balloon body by filling the balloon body with gases of different pressures. Such as image 3 The degree of expansion of the outer airbag 32 in (a) is different from that in 3(b), ...

Abstract

The invention relates to a vertically ascending multi-rotor aircraft and a horizontally ascending fixed-wing aircraft. The vertically ascending multi-rotor aircraft includes a fuselage and a side wing. The side wing is provided with a rotor, and the side wing adopts a fixed wing. structure, the fixed wing is an aircraft fixed wing, including a rigid fixed wing leading edge, and the rear side of the fixed wing leading edge is provided with a wing airbag that can expand and retract. Edge-joined airbag wing sections. The fixed wing of the aircraft includes a connection part fixedly connected with the fuselage of the aircraft. The rigid fixed wing trailing edge is fixed on the connecting part, and the leading edge of the fixed wing can swing to the rear edge of the fixed wing. A variable-sweep wing is formed. The multi-rotor aircraft vertically ascending and descending provided by the present invention can make the wing airbags in the retracted state during the ascending and descending phase, reduce the lateral stress area of ​​the fixed wing, and effectively reduce the influence of side seams on the multi-rotor aircraft vertically ascending and descending .

Description

technical field [0001] The invention relates to a vertical lift multi-rotor aircraft and a horizontal lift fixed-wing aircraft. Background technique [0002] Aircraft include fixed-wing aircraft with horizontal run and lift and rotorcraft with vertical lift. For fixed-wing aircraft, the aerodynamic characteristics of the aircraft can be changed by changing the shape of the aircraft. Generally, the ways to change the shape include setting flaps, ailerons, elevators, rudders, etc. The components involved in these ways are usually made of rigid materials, and hydraulic actuators and other types of mechanisms are required to control the changes. The overall structure and control are relatively complex. Complicated and expensive. Rotorcrafts include helicopters and multirotorcrafts. Among them, multirotorcrafts refer to aircrafts with more than two rotating shafts arranged in parallel. Multirotorcrafts can change the flight characteristics of the rotorcraft by changing the opera...
