Folding Scheme of Single Wing and Single Shaft on Light Aircraft

Abstract

The invention provides a design scheme of a light plane high mounted wing single rotating shaft folding structure. The design scheme comprises the following steps: step one, simplifying a wing model, and initially determining a structure separating surface at a rotation part of the wing; step two, determining the folded position of the wing; step three, computing a position of the rotated rotating shaft of the wing in a space coordination system; step four, adjusting the position of the structure separating surface according to the rotating shaft position and repeating the step one to step four until the wing cannot interfere with the fuselage in the rotating folding process; step five, eliminating the structure interference of the inner section and outer section of the wing in three-dimensional modelling software; step six, designing the structure at the folded separating surface; step seven, fixing the folded front wing and rear wing; and step eight, realizing the single rotating shaft folding through computer stimulation. Since the scheme enables the folded wing to cling to the fuselage through the single-shaft rotating, the folding method is simplified, the occupation area of the folded plane is reduced, and the parking and transportation of the light plane become convenient.

Description

technical field [0001] The invention relates to the technical field of aerospace vehicle structure design, in particular to a method and device for a single-axis rotating folding scheme of a single wing on a light sports aircraft. Background technique [0002] In the design of aircraft folding wings, the choice of folding scheme occupies a very important position. The form of wing folding greatly affects the structural arrangement of the wing, the weight of the wing and the folding operation process. If the folding form of the wing is unreasonable, the arrangement of the wing structure will be very complicated and difficult, the weight of the wing will increase accordingly, and the folding process will become cumbersome. [0003] In previous upper single-wing folding designs, biaxial folding schemes or upward folding schemes were mostly adopted. In the biaxial folding scheme, the rear folding of the wing is realized through the rotation of two different rotating shafts; in...

AI Technical Summary

Problems solved by technology

The operation of the biaxial folding scheme is relatively complicated, and the height of the center of gravity of the upward folding scheme changes greatly

In light sport aircraft, the use of these two folding schemes generally requires additional power devices to realize the folding process, resulting in increased wing weight, and the folding process cannot be achieved manually by a single person

[0004] For the above problems, no effective solution has been proposed
