Problems solved by technology

[0007] The advantage of the muzzle brake is that it can promote the complete combustion of the gunpowder gas and cause the gas after complete combustion to be ejected backward at a high speed. It is as obvious as a recoilless gun; the disadvantage is that it can only partially reduce the gunpowder gas sprayed forward, and the gunpowder gas sprayed backward is limited so it can only reduce the momentum of the gunpowder gas itself (in the projectile launching direction) and the impact of the gunpowder gas on the gun. The impulse of the gunpowder gas (recoil) cannot be used to balance the recoil of the barrel

Embodiment Construction

[0059] Applied to weapon systems and using cylinders.

[0060] (Note: In this part, simplified calculations and estimates are used to illustrate design ideas, design methods and calculation methods, not to obtain accurate design data.)

[0061] For example, referring to the 25mm cannon and the 25mm high-speed grenade launchers under development in various countries (such as the "Ideal Individual Combat Weapon"-OICW and "Ideal Team Support Weapon"-OCSW in the United States), the weapon design index is set as: caliber 25mm , The projectile mass is 100g, the initial velocity is 500m / s, the maximum chamber pressure is over 200MPa, and the total length of the rifling part and the slope part of the barrel is 300mm; the recoil impulse is required to be equivalent to that of the ordinary 7.62mm rifle (about 14N·s) to achieve shoulder and shoulder resistance. Motorized launch, the length of the cylinder (excluding the piston mechanism) does not exceed 400mm; the known conditions are:...

Abstract

One involves a gas delayed recoil method. This method is applied to: 1. Weapons with any caliber, chamber pressure and muzzle velocity can be launched with low recoil or recoilless. 2. Gas turbine engines, ramjet engines and rocket engines. As a combustion chamber subsystem, the working medium is changed from a constant pressure combustion mode to a constant volume combustion mode with higher thermal cycle efficiency. A piston is assembled in the barrel of the weapon (that is, the gun barrel or gun barrel). When the gunpowder gas in the barrel burns and expands to do work and launch the projectile, the piston is simultaneously pushed to move along the axis; when the "bore pressure-time curve" of the barrel Certainly, the special structural design of the piston allows the piston to move to the position of the exhaust hole opened on the barrel at the moment when the projectile exits the chamber, so that part of the gunpowder gas is ejected forward with the projectile and part of it is released. The gunpowder gas is ejected backward through this exhaust hole to form a recoil force to counteract the recoil momentum of the barrel.

Description

Technical field: [0001] This method applies to: [0002] 1. Various barrel weapon systems that use gunpowder gas to burn and expand in a closed barrel to do work to launch projectiles. The main purpose is to make the gunpowder gas spray out at a high speed in the opposite direction of the projectile movement after the projectile is fired to form a force on the barrel, thereby reducing or even offsetting the recoil of the barrel. The application of this principle can make the anti-recoil system of the weapon extremely efficient, so that weapons of any caliber, chamber pressure and muzzle velocity can be fired with low recoil or no recoil. The barrel weapon system includes: pistols, rifles, machine guns and other guns and barrel artillery of various calibers. [0003] 2. Gas turbine engines, ramjets and rocket engines. As a combustion chamber sub-system, the working fluid is transformed from a constant pressure combustion mode to a constant volume combustion mode with higher ...
