Embodiment 1

[0025] combined with Figure 1-3 As shown, a follower mechanism of a carrier-based aircraft wing folding cover, including a cover 1, an inner wing ear piece 2 fixedly installed on the inner wing, and an inner wing ear piece 3 fixedly installed on the inner wing And the link mechanism, the flap 1, the A inner wing lugs 2 and the B inner wing lugs 3 are connected to each other through the link mechanism, and the link mechanism includes a flip cover link mechanism and a follower link 6 mechanism, so The mouth cover 1 is connected with the A inner wing lug 2 through the flip cover linkage mechanism, and the B inner wing lug 3 is connected with the flip cover linkage mechanism through the follower link 6 mechanism.

[0026] The present invention is a follow-up mechanism for a wing folding flap 1 of a carrier-based aircraft. The flap 1 is flipped through a link mechanism, and the shape of the wing is a curved surface, and the folding rotation axis of the wing is arranged in the aero...

Embodiment 2

[0028] On the basis of the above-mentioned embodiments, this embodiment combines the attached Figure 1-3 As shown, further defined, the flip cover linkage mechanism includes a crank 4 and a rocker 5, the two ends of the crank 4 are respectively hinged to the port cover 1 and the A inner wing ear piece 2, and the two ends of the rocker 5 are respectively Hinged port cover 1 and A inner wing lug 2, the crank 4 and the rocker 5 are located on both sides of the A inner wing ear 2 and the hinge points do not coincide, the crank 4 and the rocker 5 on the port cover 1 The hinge points do not coincide. Wherein A inner wing lug 2 is fixed on the inner wing of the aircraft to provide support for the movement of the linkage mechanism, while the crank 4 and the rocker 5 are all hinged on the flap 1, and the hinge points do not coincide, while the other end of the crank 4 and the other end of the rocking bar 5 are hinged on the inner wing lug 2 of A but the hinge points do not coincide, ...

Embodiment 3

[0031] On the basis of the above-mentioned embodiments, this embodiment combines the attached Figure 1-3 As shown, further defined, the follower link 6 mechanism includes a follower link 6, a drive link 7 and a drive crank 84, and the two ends of the drive crank 84 are respectively hinged to the B inner wing ear piece 3 and the drive link 7. The other end of the transmission connecting rod 7 is hinged to the crank 4, and the end of the transmission crank 84 away from the B inner wing lug 3 is also hinged to the follower connecting rod 6. Wherein B inner wing lug 3 provides stable supporting force for follower link 6 mechanism, and follower link 6 is hinged at the hinge point of drive link 7 and drive crank 84, makes the small angle of follower link 6 The rotation can be converted into a large-angle rotation of the transmission link 7, and the other end of the transmission link 7 is hinged on the crank 4, so the large-angle rotation of the transmission link 7 drives the large-...

Abstract

The invention discloses a follow-up mechanism for a wing folding flap of a carrier-based aircraft, which comprises a flap, an inner wing ear piece fixedly installed on the inner wing, an inner wing ear piece B fixedly installed on the inner wing, and a connecting Rod mechanism, the mouth cover, A inner wing lugs and B inner wing lugs are connected to each other through a linkage mechanism, the linkage mechanism includes a flip cover linkage mechanism and a follower linkage mechanism, and the lid and the inner wing lugs of A are connected to each other. The wing lugs are connected by a flip linkage mechanism, and the B inner wing lugs are connected with the flip linkage mechanism through a follower linkage mechanism; the flip linkage mechanism includes a crank and a rocker, and the crank, rocker, mouth The cover and the inner wing ear of A are hinged to form a four-bar linkage mechanism, which is used to solve the problem that the traditional hinge or single-axis flap flipping method is difficult to meet the requirements of carrier-based aircraft wing folding flaps during the wing folding process.

Description

technical field [0001] The invention relates to the technical field of military carrier-based aircraft, in particular to a follower mechanism for a carrier-based aircraft wing folding flap. Background technique [0002] The development of modern aircraft carrier battle formations is an important direction for the improvement of my country's naval strength, and modern advanced carrier-based aircraft is an important manifestation of the combat capabilities of foreign aircraft carrier battle formations. Our country urgently needs to develop various types of advanced modern carrier-based aircraft. In order to carry more carrier-based aircraft under the condition of limited aircraft carrier deck and hangar space, the carrier-based aircraft needs to have the function of wing folding. Wings are folded. [0003] Modern fighters have continuously improved requirements for the aerodynamic shape of the aircraft, especially the wings are the main source of the aerodynamic lift of the a...
