Embodiment Construction

[0027] 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.

[0028] like figure 1 Shown, a kind of aircraft wing rotation retractable mechanism comprises inner wing 12, outer wing 13, driving gear 4 and is used to drive the folding actuator 2 of driving gear 4; The inner wing linkage mechanism and the outer wing linkage mechanism are hinged; the driven gear A10 and the driven gear B11 are fixedly connected to the inner wing linkage mechanism and the outer wing linkage mechanism respectively; the driving gear 4, the driven gear A10, the slave gear The driving gear B11 is an incomplete gear; the driving gear 4 and the driven gear A10 or the driven gear B11 mesh with each other at different stages; A10. The incomplete gear transmission of the driven gear B11 effectively prevents the rotary shaft from protruding out of the win...

Abstract

The invention discloses a rotary aircraft wing folding and unfolding mechanism and a folding method thereof, which mainly solve the problem existing in the prior art that the conventional folding mechanism occupies the internal space of the wing, the moving mechanism is not compact and the wing surface is uneven due to the single rotating hinge. The rotary aircraft wing folding and unfolding mechanism comprises an inner wing, an outer wing, a driving gear, and a folding actuator for driving the driving gear; an inner wing link mechanism and an outer wing link mechanism are respectively articulated with the opposite surfaces of the inner wing and the outer wing; a driven gear A and a driven gear B are respectively fixedly connected to the inner wing link mechanism and the outer wing link mechanism; the driving gear, the driven gear A and the driven gear B are all incomplete gears; and at different stages, the driving gear is engaged with the driven gear A or the driven gear B. Through the solution, the invention achieves the objectives of even wing surface and compact structure, having high practical value and popularization value.

Description

technical field [0001] The invention relates to the field of aviation equipment, in particular to an aircraft wing rotation retractable mechanism and a storage method thereof. Background technique [0002] In order to effectively reduce the storage space of the aircraft, the carrier-based aircraft needs to fold the wings on both sides when parking, so as to reduce the overall size of the aircraft. At the same time, the carrier-based aircraft should have the function of fast folding and unfolding, so as to reduce the preparation time of the aircraft before and after the ship. The traditional folding wing is usually folded and unfolded through a mechanical actuating mechanism. The horizontal folding wing is provided with a hinge at the separation surface of each section of the wing, and the outer wing part is rotated around the hinge axis by an external driving force, and the wing is upward. Or fold down against the plane of symmetry of the fuselage. In addition, the folding...
