RU2584320C1 - Method of providing recoil of centre of mass of shooting aggregate-mounted gun along barrel channel axis - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to small arms, specifically to methods of ensuring recoil of centre of mass of shooting aggregate-mounted gun. Mounted gun comprises shooting aggregate, which consists of barrel, bolt and breech frame, carriage with guide and trigger unit in mounting lock trigger and firing mechanism of firing device. Method of providing recoil of centre of mass of shooting aggregate-mounted gun along barrel channel axis consists in fact that operator on lock release mechanism of retainer, locking before a shot shooting aggregate with gun carriage, comes out of engagement with ejection unit and actuates firing mechanism of shooting aggregate, resulting in centre of mass of shooting aggregate rolls along barrel channel axis, and then shooting aggregate rolls together with gun carriage.

EFFECT: higher accuracy and closer grouping of firing.

Description

FIELD OF TECHNOLOGY

The invention relates to small arms.

BACKGROUND

The closest prototype of the claimed invention is patent 2370721, “Automatic bullpup layout small arms”, relates to small arms and can be used in a bullpup layout automatic small arms made in the form of a carriage system with the ability to roll back and return to the combat position. The weapon contains a spring return mechanism for a movable firing unit and a guide box as a gun carriage for the latter. On the guide bed there are two pistol fire control sticks located in front of the lower box magazine which is stationary when firing, and a longitudinal neck of the lower window, which serves for ejection of cartridges. The weapon has a barrel-mounted cantilever element rigidly connected to the receiver of the firing unit and equipped with a vertical rib for acting on the muzzle end of the movable male sleeve, which is telescopically connected to the stationary female sleeve, which is placed on the upper longitudinal cover of the weapon in parallel with the spring-loaded control handle of the bolt frame and is equipped with a muzzle lower longitudinal slot used to pass the vertical rib. A return spring of compression is placed inside the telescopically connected shells, which serves to move to the forward position inside the guide bed of the firing unit. The invention provides improved performance and improved design.

OBJECT OF THE INVENTION

The ability of a weapon to maintain the required accuracy and accuracy of fire unchanged under various conditions of use is called the stability of the battle, which depends mainly on its design characteristics. Improving the stability of the prototype of the claimed invention is achieved by carriage of the system with the ability to roll back and return the firing unit to the firing position. However, the spring return mechanism at the time of the shot nevertheless transmits a certain pressure pulse of the powder gases to the guide bed, as a result of which the weapon receives translational and rotational motion in both vertical and horizontal planes. The purpose of the claimed invention is to exclude the influence of an impulse of the pressure force of the powder gases on the weapon until the bullet leaves the barrel.

SUMMARY OF THE INVENTION

The way to ensure the rollback of the center of mass of the firing unit of the gun-mounted weapon along the axis of the barrel channel is as follows.

When the operator acts on the trigger trigger mechanism of the gun carriage, the trigger of the trigger trigger mechanism of the gun carriage, fixing the firing unit with the gun carriage before firing, disengages from the firing unit and activates the firing mechanism of the firing unit. As a result, the center of mass of the firing unit rolls out along the axis of the bore channel for the length of time the pulse of pressure of the powder gases acts on the bottom of the barrel channel, and then the firing unit rolls back together with the gun carriage.

SUMMARY OF THE INVENTION

A method of ensuring the rollback of the center of mass of the firing unit of the gun-mounted weapon along the axis of the barrel channel, which includes the firing unit as part of the barrel, the bolt and the bolt frame with the possibility of movement along the guide carriage, the carriage with a guide for moving the firing unit and the trigger assembly as part of the fire-trigger-trigger mechanism and the trigger mechanism of the firing unit, characterized in that when the operator acts on the trigger mechanism of the gun carriage, the stopper of the trigger mechanism and the carriage, fixing the firing unit with the carriage before firing, disengages from the firing unit and activates the firing mechanism of the firing unit, as a result of which the center of mass of the firing unit rolls along the axis of the channel for the duration of the pulse of pressure of the powder gases on the bottom of the barrel channel the barrel, and then the firing unit is rolled back together with the carriage.

DETAILED DESCRIPTION OF THE INVENTION

Materials and technology for the implementation of the claimed invention do not go beyond the scope of modern capabilities.

Claims (1)

A method of ensuring the rollback of the center of mass of the firing unit of the gun-mounted weapon along the axis of the barrel channel, which includes the firing unit as part of the barrel, the bolt and the bolt frame with the possibility of movement along the guide carriage, the carriage with a guide for moving the firing unit and the trigger assembly as part of the fire-trigger-trigger mechanism and the trigger mechanism of the firing unit, characterized in that when the operator acts on the trigger mechanism of the gun carriage stopper trigger trigger the gun mount, which detects the firing unit with the gun mount before firing, disengages from the firing unit and activates the firing mechanism of the firing unit, as a result of which the center of mass of the firing unit rolls along the axis of the channel for the duration of the pulse of pressure of the powder gases on the bottom of the barrel channel the barrel, and then the firing unit is rolled back together with the carriage.
