Shell-free bullet with hollow bullet body and launching gun barrel thereof

Abstract

The invention discloses a shell-free bullet with a hollow bullet body and a launching gun barrel thereof. The shell-free bullet is composed of three main parts of the hollow bullet body, an artillery primer and propellant powder. The propellant powder has dampproof and loss prevention functions. The temperature of a chamber is low at the time of shooting, so that a cook-off phenomenon does not occur to the bullet. The shell-free bullet is launched by an exhaust rifling gun barrel and a blasting wing smoothbore barrel, the firing range is far, precision is high, and the killing ability is large. The shell-free bullet is small in volume, light in weight, concise and attractive, firm and reliable, and easy to manufacture, and the material is saved. Based on the shell-free bullet with the hollow bullet body and the launching gun barrel thereof, conventional firearm parts such as bullet supplying parts, locking parts, automatic parts, percussion parts, safety parts, aiming parts, holding parts and food frame parts are combined to constitute various large, middle and small caliber series of bullet firearms such as rifles, machine guns, handguns and submachine guns, so that different battlefield effects are given play, different fighting tasks are finished, and the shortcomings of a G11 shell-free bullet gun and a traditional bullet are overcome.

Description

technical field [0001] The invention relates to the technical field of bullets and firearms, in particular to hollow shells without casings and firing barrels thereof. Background technique [0002] After nearly a thousand years of hard work by human society, the firecracker invented in the Song Dynasty in my country has now developed into a modern bullet ( figure 1 ) and firearms. Although today's warfare has been changing with each passing day, bullets and firearms are still the basic weapons for human warfare, and all weapons manufacturing companies in the world are actively carrying out continuous innovation and development of bullets and firearms. The G11 caseless bullet gun, which the company has jointly developed for more than 20 years, is an epoch-making innovation. The bomb has a semi-embedded warhead ( figure 2 ) and warhead fully embedded ( image 3 ) The two structures are composed of a conventional warhead, a hollow propellant column, a support tube, a prime...

AI Technical Summary

Problems solved by technology

[0003] However, while the G11 caseless bullet gun has advantages, it also has the following disadvantages: 1. Since the bullet does not have a metal case, there is no heat dissipation function on the gun, and there is no metal case heat insulation between the propellant and the barrel. The temperature is high, and the propellant is easy to cook and cause the bullet to ignite by itself. Therefore, it is necessary to develop and use high ignition point propellant

2. The hollow propellant column of G11 caseless bullets is not protected by metal shells, so it is easy to be damp and damaged, which not only increases the workload of service and maintenance, but also is restricted in use

3. The rotary bolt action increases the difficulty of wiping, cleaning and other service maintenance

4. The G11 caseless bullet gun method is suitable for small-caliber firearms, but it is difficult to use large-caliber firearms
