Automatic firearm having an inertial automatic system

Abstract

An automatic firearm having an inertial automation system comprises a barrel, which is movable along its own axis, a bolt support with a bolt, a recoil spring, a buffer spring and a hammer spring, a trigger mechanism, an ammunition feed mechanism, a mechanism for coordinating the actual firing, and a bolt support latch. The springs and the mechanism for coordinating the actual firing ensure a constant-value recoil force during automatic fire. Technical result consists in the improvement of the shooter's operating conditions, reduced vibration, and decreased bullet dispersion.

Claims

1. An automatic firearm having an inertial automation system with recoil throughout the entire time of automatic fire having a force of a certain constant value acting on a support, comprising a breech; a barrel, which is movable a longitudinal axis; a bolt support with a bolt; a hammer spring between the barrel and the bolt support; a recoil spring between the bolt support and a guide stop; a buffer spring between a rear wall of the breech and the guide stop; an ammunition feed mechanism for loading of ammunition into the firearm wherein said loading causes the bolt support to retract and attach to a latch for locking the bolt support in a rear position, a trigger mechanism that, when pressed, causes the latch to release the bolt support which accelerates forward in the direction of the barrel assisted by the recoil spring.

Description

(1) As an example, the drawing (FIG. 1) illustrates the design, which utilizes the inertial automation system while associating the bolt support (with the bolt) and the barrel. A weapon breech (1) houses a latch (2), and a barrel (3), which is movable along its own axis. A guide (4) is attached to the barrel, and bolt support (5) with bolt (6) is movably attached to said guide. A hammer spring (7) is attached to the bolt support. A recoil spring (9) is installed between the bolt support and a guide stop (8), while a buffer spring (10) is installed between the guide stop and the rear wall of the breech. The order of operation of the design is similar to the one described above.

(2) According to the calculations, in case of the automatic firing rate of 600 rounds per minute, a near-constant force pressing on the support (shooter's shoulder, weapon mount, combat vehicle body) will be as follows (newtons/kilogram-force) for the cartridges: 5.45×39-35/3.6; 7.62×39-55/5.6; 7.62×54R-90/9.2; 12.7×108-400/41; 14.5×114-650/66.

(3) The pressing force increases or decreases proportionally with an increase or decrease in the rate of fire.
