Problems solved by technology

The surface of the known game bullets is designed to be smooth and convex in order to reduce wind resistance, and there is still room for improvement, because the shark skin bionic technology has not yet been applied in the field of sports game bullets

Embodiment Construction

[0010] Bullets with a sharkskin surface texture, see figure 1 , is made up of shell case 2, primer, propellant, warhead 1 four parts, is characterized in that:

[0011] The surface texture of the warhead imitates the V-shaped folds on the surface of the shark skin, and is characterized in that: a circle of tightly arranged V-shaped folds unit 3 imitating the shark skin starts from the vicinity of the top of the warhead and is arranged downwards in one direction , has been discharged to the bottom of the warhead. When the warhead is launched, the V-shaped folds imitating shark skin can reduce its wind resistance, and the warhead can hit the target more accurately.

[0012] The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any form. Any simple modification, equivalent Changes and modifications all still belong to the scope of the technical solution of the present invention.

Abstract

The invention discloses a cartridge with sharkskin-structure surface texture. The cartridge consists of a cartridge case, a primer, a propellant powder and a cartridge head, and is characterized in that the surface texture of the cartridge head simulates the V-shaped wrinkles at the sharkskin surface; one circle of densely-arranged sharkskin-simulated V-shaped wrinkle unit uses the area near the top part of the cartridge head as the starting point, and is arranged down along one direction until to the bottom part of the cartridge head; when the cartridge head is ejected out, the air drag can be reduced by the sharkskin-simulated V-shaped wrinkles, and the cartridge head can more accurately hit the target. The cartridge has the beneficial effects that the air drag can be reduced, and the cartridge head can more accurately hit the target.

Description

technical field [0001] The invention relates to a sporting article, in particular to a bullet whose surface texture is a sharkskin structure. Background technique [0002] Biologists have found that the V-shaped folds on the surface of the shark's skin can reduce the friction of the water flow, so that the water around the body can flow through more efficiently, and the shark can swim quickly. For this reason, a company has developed a shark skin swimsuit, whose super-stretch fiber surface is completely imitated from the surface of shark skin. Experiments have shown that this swimsuit can reduce water resistance by 3%, which is of great significance in swimming competitions where the outcome can be determined in 1% of a second. Practice has also proved that athletes wearing sharkskin swimsuits have achieved very good competition results. The surface of the known game bullets is designed to be smooth and convex in order to reduce wind resistance, and there is still room for...
