Description

Technical Field

[0001] The utility model relates to the technical field of unpowered projectile structures, in particular to a folding wing structure of a projectile. Background Art

[0002] In modern air-to-air combat, there's an increasing demand for droppable active radio frequency decoy flares to jam and deceive air-to-air missiles. These flares must be released from a carrier aircraft and maintain stable, unpowered flight. To ensure safe detachment from the carrier aircraft and maintain long-term stability after detachment, the decoys themselves must possess excellent aerodynamic capabilities. Existing decoy flares often utilize fixed-wing structures, which consumes more ammunition storage space.

[0003] Therefore, it is necessary to develop a folding wing structure of a projectile to solve the above problems. Utility Model Content

[0027] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, a folding wing structure of a projectile includes:

[0029] Four folding wings 2; two first mounting slots 11 are provided on the projectile body 1, located on two opposing sides of the projectile body 1; second mounting slots 12 are provided on both sides of each first mounting slot 11 and located on the prism of the projectile body 1. The rotating portions of the four folding wings 2 are rotatably mounted in the second mounting slots 12, and the first ends of the torsion springs 22 of the folding wings 2 are connected to the projectile body 1; the winglets 23 of the two folding wings 2 on one side of the projectile body 1 are stacked up and placed on one of the first mounting slots 11 when the projectile body 1 is not in use. The decoy projectile adopts a rectangular outer structure;

[0030] like Figure 4-5 As shown, in some embodiments, the setting height of the first installation groove 11 is higher than the setting height of the second installation groove 12; and the bottom cross-section of the second installation groove 12 is semicircular, and correspondingly, the rotating sleeve 24 is annular.

[0031] like Figure 3-4 As shown, in some embodiments, a mounting notch 14 is provided on both sides of the first mounting slot 11, and the first end of the torsion spring 22 is fixedly installed in the mounting notch 14. In some cases, two mounting notches 14 are provided on both sides of the first mounting slot 11 to accommodate different installation postures of the torsion spring 22.

[0032] like Figure 3-4 As shown, in some embodiments, the folding wing 2 further includes a rotating shaft 21 and two rotating sleeves 24. The sidewall of the rotating sleeve 24 is connected to the first side of the wing 23. The rotating sleeve 24 and the torsion spring 22 can both be mounted on the rotating shaft 21. The second end of the torsion spring 22 is connected to the first side of the wing 23. The second mounting slot 12 is provided with an axial hole 13 at both ends. The two ends of the rotating shaft 21 are rotatably mounted in the two axial holes 13. The torsion spring 22 is placed between the two rotating sleeves 24. The length between the outer ends of the two rotating sleeves 24 is slightly less than the length of the second mounting slot 12.

[0033] In some embodiments, when the projectile 1 is not in use, the top height of the wing pieces 23 of the two folding wings 2 after being overlapped is no higher than the surface of the projectile 1 .

[0034] In some embodiments, both ends of the rotating shaft 21 may be rotatably connected to the elastic body 1 through bearings.

[0035] In some embodiments, both ends of the rotating shaft 21 may be fixedly installed in the shaft hole 13 .

[0036] The present application does not show the limit release mechanism of the folding wing 2 structure, but the limit release mechanism is not within the scope of protection of the present application. Any limit release mechanism disclosed in the prior art will suffice as long as it can block the winglets 23 at the top and bottom surfaces when the folding wing 2 structure is folded.

[0037] When the present application is working, the projectile 1 is generally a bait bomb. After being launched from the limit release mechanism, the two folding wings 2 located on one side of the projectile 1 will unfold the upper one first and then the lower one. The unfolding process is that the torsion spring 22 drives the wing 23 to rotate under the elastic action. After the torsion spring 22 is elastically released, the wing 23 is fixed in position. The cooperation between the rotating sleeve 24 and the second mounting groove 12 plays a role of radial limitation and circumferential guidance.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
