Problems solved by technology

Most of the existing wing folding methods are to fold the outer end of the wing inward from the middle of the wingspan. For aircraft with a relatively small aspect ratio such as carrier-based aircraft, the space occupied by this folding method is only about half of the wingspan , reducing the footprint; for aircraft with a large aspect ratio, this folding method still has half the extended width after folding, which cannot achieve flexibility and miniaturization

Abstract

The invention discloses a flexible foldable wing, and belongs to the technical field of aircraft devices. One side of the wing base is connected with the root of an aircraft wing, the front end of the other side of the wing base is rotationally connected with the root of the leading edge main beam, the rear end of the other side of the wing base is rotationally connected with the root of the trailing edge auxiliary beam, and the folding servo transmission system is connected with the root of the leading edge main beam and the root of the trailing edge auxiliary beam. The tip of the front edge main beam is hinged to the wingtip base, and the tip of the rear edge auxiliary beam is hinged to the wingtip base; two ends of the plurality of wing ribs are respectively hinged with the leading edge main beam and the trailing edge auxiliary beam; the wing base, the wingtip base, the front edge main beam, the rear edge auxiliary beam and the wing ribs are wrapped with the flexible skin, and a complete pneumatic wing shape is formed. The aircraft wing can be highly folded, the size of the aircraft in storage and transportation is reduced, the flexibility of the aircraft is improved, and miniaturization of the aircraft is achieved.

Description

technical field [0001] The invention belongs to the technical field of aircraft devices, and in particular relates to a flexible foldable wing. Background technique [0002] The wing is the main device for providing lift during the flight of the aircraft, and its wing area largely affects the lift of the aircraft, so the aircraft often needs a larger wing area to maintain the flight lift. Generally, aircrafts use wings with a large aspect ratio to improve flight efficiency, but the wings with a large aspect ratio greatly increase the space occupied by the aircraft structure and reduce the flexibility of storage and transportation of the aircraft. [0003] Modern aircraft pay attention to flexibility and miniaturization, and have strict requirements on the volume of the aircraft, such as carrier-based aircraft, miniature reconnaissance drones, etc., the wings need to be folded to reduce the volume of the aircraft. Most of the existing wing folding methods are to fold the out...
