Problems solved by technology

[0009] 1. The existing technology generally uses a one-time folding wing. After folding, a launcher with a larger launch diameter is still required, and the volume is relatively large.
[0010] 2. With a one-time folding wing, the additional moment of rotation generated by the expansion of the wings is large, and the required control torque is large, and the aircraft model aircraft is not easy to control

Embodiment Construction

[0034] Such as Figure 1~4 As shown, a foldable wing, three interconnected fins 1, two adjacent fins 1 are connected by a hinge seat 4, and the innermost fin 1 and the fuselage 3 are connected by a hinge seat 4 connections.

[0035] A through hole is formed on each hinge seat 4 where it abuts against the lower end of the wing 1 , and a locking mechanism is arranged in the through hole. The locking mechanism includes a wedge 7 that can telescopically slide in the through hole, and a plug 8 for preventing the wedge 7 from slipping out of the through hole. A compression spring 9 is provided between the plug 8 and the wedge 7 . The wedge 7 can be wedged tightly with the bevel of the straight chamfer 6 . After the flap 1 is folded, the compression spring 9 is completely compressed, and the wedge 7 is separated from the straight chamfer 6 .

[0036] The hinge seat 4 includes a front seat body 41 and a rear seat body 42 arranged at intervals. The front seat body 41, the wings 1,...

Abstract

The invention discloses a folding wing which comprises at least two wing panels. The wing panels are connected with one another, every two adjacent wing panels are connected with each other by a hinge seat, and the wing panels which are positioned on the innermost side of the folding wing are connected with a fuselage by hinge seats; an unfolding mechanism is arranged between every two adjacent wing panels and is used for unfolding the wing panels towards the directions far away from the fuselage, and unfolding mechanisms for unfolding the wing panels towards the directions far away from the fuselage are arranged between the fuselage and the wing panels which are positioned on the innermost side of the folding wing; through holes are formed in butted joints of each hinge seat and the lower end of the corresponding wing panel, and locking mechanisms are arranged in the through holes; limiting mechanisms are arranged on the lower surface of a hinge joint of every two adjacent wing panels and can prevent the wing panels from rotating to reach positions below horizontal planes. The folding wing has the advantages that the diameters of model airplanes can be reduced to the greatest extent during launching and transporting, and the folding wing is easy to control.

Description

technical field [0001] The invention belongs to the field of aircraft, and in particular relates to a folding wing. Background technique [0002] The quality and outline size of model airplanes are one of the important symbols of technical level. An effective way to reduce the overall size of model airplanes is to use folding wings. With the development of model aircraft technology, especially the advancement of launch technology, storage and transportation launchers are widely used, and folding wings can also reduce the lateral size of the launch tube, creating conditions for the integrated design of launchers and model aircraft. [0003] There are two common folding methods for folding wings: [0004] The first is that the wings are folded around an axis parallel to the longitudinal axis of the model aircraft, which is mostly used on wings with small aspect ratios. [0005] The second is that the wing is folded around an axis perpendicular to the tail chord plane, which...
