Supercavitation bullet

Abstract

The invention discloses a supercavitation bullet, and relates to the technical field of bullets. The supercavitation bullet comprises a support body and a cavitator, wherein the support body is sequentially provided with an embedded part, a rear groove part, an inclined part and a support body tail end from one side to the other side, the embedded part, the rear groove part, the inclined part and the support body tail end are integrally formed, and the embedded part is embedded into the cavitator; and the end, close to the support body, of the cavitator is provided with a groove matched with the embedded part, the rear groove part is columnar, the radius of the rear groove part is less than that of the end face of the end, close to the support body, of the cavitator, the tail end of the support body is columnar, the radius of the tail end of the support body is greater than that of the rear groove part, and an inclined part transition is arranged between the tail end of the support body and the rear groove part. Through the arrangement of the supercavitation bullet, the supercavitation bullet of 5.8 * 42 mm, which can keep large power underwater, is provided.

Description

technical field [0001] The invention relates to the technical field of bullets, in particular to a supercavitating bullet. Background technique [0002] Bullet warhead is one of the important parts of gun ammunition. The conveying structure of the gun chamber is formed between the surface of the bullet and the inner surface of the gun to facilitate the firing of bullets. When firing, the bullet relies on the impact force generated by the burning of gunpowder to launch. Due to the special underwater combat environment, ordinary bullets are designed for use in the air. When shooting in water, since the density of water is about 800 times that of air, the viscosity and resistance are much higher than air. The warhead will fully release its own kinetic energy within a very short flight distance, and its lethality will drop sharply. [0003] Therefore, the ordinary bullets that are mainly used in individual combat cannot be shot in water, which has become the main problem for so...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the ordinary bullets that are mainly used in individual combat cannot be shot in water, which has become the main problem for soldiers to perform special operations tasks underwater. Underwater shooting, currently only a few countries have experimented with supercavitating ammunition, and only Norway has announced that it has developed a 7.62x51mm underwater supercavitating ammunition, while the 5.8x42mm high-power supercavitating ammunition Bubble bullet technology still hasn't made any progress
