Membrane wing folding system and membrane wing aircraft thereof

Abstract

The invention provides a membrane wing folding system which comprises two inner cross beams fixedly arranged at the top of a machine body, the two ends of each inner cross beam are connected with outer cross beams through electric folding mechanisms, wing membranes are arranged between the two inner cross beams and between the two outer cross beams, and each electric folding mechanism comprises a rotating motor, a push-pull screw, a power spiral sleeve and a rotating connecting rod. The rotating motor is connected with and drives the spiral sleeve to rotate, the spiral sleeve is arranged on the push-pull screw in a sleeving mode and is in threaded connection with the push-pull screw, the push-pull screw is arranged in the inner cross beam in a sliding mode, one end of the rotating connecting rod is rotationally connected with the end of the push-pull screw, the other end of the rotating connecting rod is rotationally connected with the outer cross beam, and the outer cross beam is rotationally connected with the inner cross beam. Before taking off and landing, the wing membrane is folded and put away, namely the effect of reducing the resistance of the wing to the dual-mode aircraft in the vertical direction when the dual-mode aircraft ascends and descends can be achieved, and then the purpose of ensuring that the dual-mode aircraft applying the membrane wing folding system has high operation stability when the dual-mode aircraft ascends and descends vertically is achieved.

Description

Technical field[0001]The present invention relates to the technical field of low-altitude aircraft, and more particularly to a membrane wing folding system and a membrane wing aircraft.Background technique[0002]At present, the existing aircraft is more common in terms of two structural forms. One is a fixed wing slip-down aircraft. There are long fixed wings on both sides of the aircraft. The fixed-wing aircraft is fast, and the energy saving efficiency is high. Long cruise time, large load capacity, but take-off and landing, it needs to take a lifting slide, so that this fixed-wing's slippery aircraft is very high in the place where the landing is very high, and there is usually a fixed airport to take off and land. The cost and maintenance cost is very high; the other is a roller slide vertical lifting aircraft, that is, helicopter, such aircraft characteristics is the flexibility, hover, completed, such as hoisting, field transport, etc. It is necessary to have a large take-off l...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention proposes a membrane wing folding system and its membrane wing aircraft to solve the following technical problems mentioned in the background technology: the resistance of the fixed wing when the existing dual-mode aircraft takes off and lands vertically Larger, it is prone to take-off and landing instability, and when not in use, it takes up a lot of space. The structure of the fixed wing still adopts the original fixed-wing aircraft structure, which is heavy
