Weapon system composed of multi-section gun tube and fluid-driven spinning projectile and method

Abstract

The invention discloses a multi-section gun tube, a fluid-driven spinning projectile and a weapon system composed of the multi-section gun tube and the fluid-driven spinning projectile. A volute hole or slot is formed in the rear or tail part of the projectile to guide a propellant gas and is combined with the multi-section gun tube, so that the projectile can form spinning in a hydrodynamic way instead of depending on rifle cutting. By virtue of such a trial, the projectile spinning can also be realized while the high bore pressure, high initial speed and low resistance of a smoothbore gun are achieved, and the costs of the gun tube and the projectile are reduced.

Description

technical field [0001] The invention relates to a weapon system in which a vortex groove or a vortex hole is arranged at the rear or tail of a projectile and matched with a multi-section barrel, and relates to barrel weapons such as guns and cannons, and belongs to the field of military industry. Background technique [0002] At present, except for a few types of smoothbore weapons such as large-caliber smoothbore guns, most of the barrel weapon systems are basically rifled weapon systems. [0003] The rifled weapon system uses the extrusion and friction of the rifling to make the projectile rotate, thereby achieving the stability of the projectile during flight. However, this method will inevitably produce severe friction and cutting between the projectile and the rifling, resulting in a decrease in the kinetic energy of the projectile exit. At the same time, because the protrusion of the rifling makes it difficult for the barrel to be sealed by the projectile or the belt, ...

Problems solved by technology

[0010] Moreover, on the basis of solving the above technical problems, it is combined with the existing bullet holder technology, and a taper sleeve structure is formed by setting corresponding tapers in the bullet holder cavity and the tail of the bullet core, and a structure with a more improved structure is invented. It is a simple shelling bomb, launching system, and a direct backward shelling method, which further solves the current shelling shells, which have complicated shell holders, complex connection methods of bullet holder cores, and complicated shelling methods, resulting in high cost and high cost.
