Embodiment Construction

[0018] The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.

[0019] Such as figure 1 and figure 2 As shown, a kind of aircraft wing folding mechanism comprises inner wing 1, outer wing 6 and folding actuator 5; The upper parts of the end surfaces are respectively hinged; the folding actuator 5 has two output ends, and the first-stage revolving pair and the second-stage revolving pair are respectively hinged between the two output ends and the lower parts of the end faces of the inner wing 1 and the outer wing 6 The above-mentioned structure forms a double-hinge rotary structure, which can effectively avoid the situation that the folded rotary shaft protrudes from the surface of the wing, ensures that the joint surface of the wing after deployment is smooth, and reduces aerodynamic resistance during flight.

Abstract

The invention discloses an aircraft wing folding mechanism and a covering cap mechanism based on the aircraft wing folding mechanism and mainly solves the problems in the prior art of unevenness of wing joint surfaces due to the existing wing folding, absence of a covering cap and complex structure of the covering cap. The aircraft wing folding mechanism comprises an inner wing, an outer wing anda folding actuator, wherein the folding actuator is arranged between the inner wing and the outer wing and is respectively hinged with the upper parts of the end surfaces of the inner wing and the outer wing; the folding actuator is provided with two output ends; and a first stage rotation pair is hinged between one output end and the lower part of the end surface of the inner wing, and a second stage rotation pair is hinged between the other output end and the lower part of the end surface of the outer wing. By virtue of the technical solution, the aircraft wing folding mechanism and the covering cap mechanism based on the folding mechanism achieve the purpose of evenness of the wing joint surfaces and have high practical value and popularization value.

Description

technical field [0001] The invention relates to the technical field of aviation airborne equipment, in particular to an aircraft wing folding mechanism and a flap mechanism based thereon. Background technique [0002] Aircraft wing folding is to reduce the wingspan of the aircraft and reduce the space required for parking the aircraft by rotating a part of the wing at a certain angle and then flipping and folding it. Wing folding technology can not only meet the purpose of saving deck space of carrier-based aircraft, but also increase the demand for carrying capacity. It can also effectively reduce the space occupied by aircraft transportation and hangar storage, which has certain significance for the use of various small and medium-sized aircraft. [0003] The wing folding mechanisms of aircraft in the prior art all adopt the form of a single hinge. The rotation axis of the outer wing is perpendicular to the span direction and is located on the upper part of the wing skin....
