RU2561185C1 - Revolver with blowback compensation - Google Patents

Abstract

FIELD: weapon and ammunition.

SUBSTANCE: revolver contains one or several barrels and a drum. The barrel in breech end is finished by a flanging enclosing a drum with a groove. The groove together with flanging form the channel for escaping powder gases and form a flow for creation of the jet force reducing blowback effect.

EFFECT: enhanced accuracy, reliability improvement and weapon life increase.

Description

The invention relates to firearms using the revolving principle of supply of ammunition, and can be used to improve the combat properties of such weapons in terms of increasing accuracy.

Keywords: revolver, drum principle of supply of ammunition, recoil, jumps during firing, leakage of powder gases, firing accuracy

It is known that a common drawback of the design of revolvers is the unproductive leakage of powder gases into the gap between the barrel and the drum, with the exception of revolvers of the Nagan and Piper systems [1, p. 34], in the construction of which the obturation is provided by an elongated cartridge case and a special revolver device that propels the drum forward with the cartridge barrel pulled into the barrel channel. When fired, the muzzle is heard and closes the gap, which reduces gas leakage.

A recoil-compensated revolver not only eliminates this previously insurmountable drawback of a revolver weapon by using powder gases bursting from the breech of the barrel when firing to create a reactive force that reduces recoil, and thereby increases accuracy. A weapon prototype was not found during the search.

Closest to the prototype can be attributed revolver "Iver Johnson, model 55C," Cadet "" [1, p. 63, fig. 16-172]. In the design of the specified revolver, the front surface of the drum is surrounded by a side that prevents the spread of powder gases to the sides through the gap between the drum and the barrel, to reduce the unpleasant effect of powder gases on shooters adjacent to the line of fire. Other benefits from the use of the proposed design is not given, which does not allow to include the design of the specified revolver to the prototypes.

The purpose of the invention is improving the accuracy of the battle of a revolver. The goal is achieved by using the energy of the flow of powder gases breaking into the gap between the drum and the barrel. Gases are sent back in the direction of fire, reactive forces compensate recoil from a part and facilitate firing. The proposed design features can be applied in any weapon using the revolving principle.

The purpose of the invention is achieved by the construction, the scheme of which is presented in FIG. 1-4, where it is indicated: 1 - trunk; 2 - flange; 3 - flanging; 4 - groove of the drum; 5 - channel for gases; 6 - gas flow, 7 - frame.

The proposed design does not eliminate the gas leakage between the drum and the barrel, but uses it for useful purposes, i.e. to reduce returns. When designing weapons to enhance the inhibitory effect, special clearance structures are created (4) that regulate both the direction and energy of the flow of bursting gases (6). The configuration of the channels (5) may also have a different form.

The advantages of this invention include the so-called compensating effect, which is achieved not due to the addition of a muzzle brake (built-in compensator), but due to the beneficial use of one of the main design drawbacks of the revolver, namely the dispersion of powder gases into the gap between the drum and the barrel. Thus, such a disadvantage as the "large return" inherent in revolvers designed for the use of large-caliber cartridges and power is reduced. Special design of the gaps establishes such a direction of outflowing reactive gases, which eliminates the burns of fingers or face, even in an inexperienced shooter.

The accuracy of hitting when shooting from a revolver with recoil compensation will not depend on the physical strength of the shooter, while the design retains all the advantageous characteristics inherent in revolvers, namely the minimum time for ready for the first shot, fault tolerance, reliability and durability.

The scope of the revolver with recoil compensation fully extends to all guns using the revolving principle of supply of ammunition for both civilian, official and military purposes, i.e. in designs of revolving hunting rifles, special manual and automatic grenade launchers, including guns of the “Traund” type of Darik. The proposed recoil compensation principle of the revolver is also applicable in the design of revolving guns [2], since it allows to eliminate the main disadvantages inherent in this type of guns [3].

Claims (1)

A revolver containing one or more barrels, a drum, characterized in that the barrel in the breech ends with a flange with a flange, covering the drum with a groove, which together with the flare form a channel for bursting powder gases and form a flow to create a reactive force that reduces the recoil effect.
