Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see figure 1 , the embodiment of the present invention discloses an underwater rotation-stabilized supercavitating bullet, comprising a holder body 1 and a cavitator 2, one end of the cavitator 2 has a groove 3, and the end provided with the groove 3 is The tail of the supercavitating bullet, the other end of the cavitator 2 is a plane. The support body 1 includes an inlay body 11, a first cylinder 12 and a cone 13. The inlay body 11, the first cylinde...

Abstract

The invention discloses a supercavity bullet capable of stably rotating underwater, and relates to the technical field of bullets. The supercavity bullet comprises a support and a cavitator, wherein one end of the cavitator is provided with a groove, the support comprises an embedment body, a first cylinder and a cone, the embedment body, the first cylinder and the cone are sequentially connected, and the embedment body is adaptively connected with the groove. According to the supercavity bullet, the end, away from the support, of the cavitator is a plane, so that the supercavity bullet moving underwater can burst through water flow to form supercavity; meanwhile, the outer surface of the cavitator is designed into a variable-conicity conical surface, so that the effect of reducing resistance can be achieved; in combination with the arrangement of the first cylinder on the support, a groove-shaped structure is formed in the area, and the groove-shaped structure can play a role in adjusting the mass center of the bullet; and meanwhile, lift force can be generated by arranging the first cylinder and the cone on the support, the precision is improved, and then the stability of the supercavity bullet in the air and in water can be improved.

Description

technical field [0001] The invention relates to the technical field of bullets, in particular to an underwater rotation-stabilized supercavitation bullet. Background technique [0002] Due to the special underwater combat environment, ordinary bullets are designed to be used in the air. When shooting in water, since the density of water is about 750 times that of air, the viscosity and resistance of water are much higher than that of air, causing bullets to The shooting range in water is shortened, and the stability of bullets in water is poor, which greatly reduces the hit rate and lethality of underwater shooting. [0003] Existing underwater bullets adopt a special long-rod arrow-shaped structure to ensure that the bullets remain stable when flying underwater, while having reliable hit rate and lethality. However, there are many disadvantages in the rod-type arrow-shaped bullet: the one is that the bullet must be fired with a special firearm due to its elongated shape; ...
