Description

The invention relates to the field of airsoft or pneumatic technology and can be used to simulate the operation of military small arms in simulators, attractions, military sports games.

Known inventions aimed at achieving the goals of simulating firing from military small arms do not fully solve the problem of full-fledged imitation of firing from military small arms.

Thus, airsoft and pneumatic weapons are known and widely used, throwing a special projectile - airsoft balls, lead bullets or balls for pneumatics, due to the energy of compressed air. This weapon is divided into subgroups: electro-pneumatic, gas or spring, where the source of compressed air is an electric drive, a gas cylinder or a pump with manual pumping (cocking). The disadvantage of airsoft and pneumatic weapons is an incomplete imitation of firing from a military weapon, since there are no corresponding sound effects, recoil, automatic operation, similar to military weapons, the use of light-and-sound cartridges and blank cartridges, which is typical when firing from a blank weapon, is impossible.

In turn, the claimed invention more fully solves the problem of simulating firing from a combat small arms, since the combination of the functionality of an airsoft or pneumatic weapon with the functionality of a chilled weapon makes it possible to achieve sound effects, recoil, and automatic operation similar to military weapons when working with sports and gaming weapons.

Also known inventions:

1) A pyropneumatic weapon (patent RU 2690140 C1), characterized by the fact that the projectile in it receives a directed movement due to the energy of compressed air, and the air is compressed due to the energy of a powder pyro charge. After the initiation of the squib, part of the powder gases acts on the piston to produce compressed air, due to which the projectile is fired.

2) Pneumatic training nozzle (patent RU 2680952 C1), characterized in that a special nozzle is attached to the muzzle of the barrel of a combat or blanked weapon, containing projectiles, a barrel for throwing projectiles, a compression chamber, a piston, a gas outlet channel. After the initiation of the squib, part of the powder gases acts on the piston to produce compressed air, due to which the projectile is fired.

In contrast to the inventions "Pyropneumatic weapon" and "Pneumatic training attachment", the present invention has a simpler design associated with the direct effect of powder gases on the projectile, practically does not make changes to the design of a blanked weapon, leaving it in a deactivated state, by using an additional the barrel, has design features of the magazine and the supply of projectiles to achieve strict compliance with the number of projectiles and flash-noise cartridges, which allows you to work with a change of magazines, as in military weapons.

The present invention has the following structural and functional differences, expressed in:

1. direct impact of part of the powder gases on the projectile;

2. the presence of a separate barrel for throwing a projectile, which allows not to use the main barrel, which remains in a deactivated state;

3. design features of a separate detachable magazine for placing projectiles and flash-noise cartridges with synchronization of the number of projectiles and flash-noise cartridges, which allows you to work with a change of magazines, as in military weapons;

4. the mechanism for supplying projectiles from the magazine to the barrel, due to the direct impact of part of the powder gases;

5. the possibility of using the Rank-Hilsch vortex tube as a refrigerator for cooling a part of the powder gases intended for projectile throwing in order to prevent the destructive thermal effect of high-temperature powder gases on a low-melting plastic or lead projectile;

6. regulation of the projectile ejection energy by changing the diameter of the channel for the supply of powder gases. For different types of projectiles, a gas regulator can be used.

Also known is the "Training nozzle" (patent RU 2674917 C1), characterized in that a special nozzle is attached to the muzzle of the barrel of a combat or blanked weapon, containing projectiles, a barrel for throwing projectiles, spring-loaded elements for sending projectile equipment, a gas channel designed to pass a smaller part of the gas, and a channel for the exit of most of the gas. After the initiation of the squib, part of the powder gases acts on the projectile in the nozzle, firing a shot.

Disadvantages of the invention

1. due to the small volume of the muzzle nozzle, the barrel for throwing a projectile is very short, which affects the range and accuracy of projectile throwing;

2. the location of the magazine for projectiles in the nozzle itself severely limits the number of shells, there is no possibility to change the magazine, there is no synchronization of the number of projectiles with the number of blank cartridges;

3. strong thermal effect of hot powder gases and a hot barrel on a projectile, leading to its destruction / melting.

These shortcomings of the invention "Training nozzle" significantly distort the effect of working with him, as with a military weapon.

Unlike the "Training Head" invention, the present invention:

1. instead of a short nozzle on the muzzle of the barrel, it has a full-fledged long barrel for throwing a projectile, which makes it possible to obtain characteristics in terms of range and accuracy similar to airsoft or pneumatic weapons;

2. allows you to use a separate, detachable magazine of excellent design for placing projectiles and flash-noise cartridges with synchronization of the number of projectiles and flash-noise cartridges, providing work with changing magazines, as in military weapons;

3. can be equipped with a Rank-Hilsch vortex tube as a compact cooler for cooling a part of the propellant gases in order to prevent the destructive thermal effect of high-temperature powder gases on a fusible plastic or lead projectile;

4. Allows you to adjust the ejection energy of the projectile by changing the diameter of the channel for supplying powder gases. For different types of projectiles, a gas regulator can be used.

There are various designs of magazines for cooled weapons containing flash-noise cartridges. Various designs of stores for airsoft and pneumatic weapons are known, combining a gas cartridge and a hopper for balls (patent US 9,022,015 B2; patent RU 2172459 C1; patent RU 2242696 C2).

When fired, the compressed gas from the cartridge presses on the ball and pushes it out of the magazine into the barrel, followed by acceleration in the barrel bore.

The design of the magazine proposed in this invention serves to solve the main problem of combining the functionality of an airsoft or pneumatic weapon with the functionality of a chilled weapon in order to most fully simulate firing from a military weapon. Unlike existing designs, this invention proposes that the throwing of an airsoft or pneumatic projectile is carried out due to the energy of a part of the powder gases generated when fired with a flash-noise cartridge, is directly used to accelerate the projectile in a separate barrel, similar to that used in airsoft or pneumatic weapons, with This uses a single store for flash-noise cartridges with a bunker containing projectiles for pneumatic or blanked weapons - airsoft balls, lead bullets or balls for pneumatics, a part of the powder gases generated when fired with a flash-noise cartridge is fed through the feeder directly into the ball bin and sent into the barrel, followed by acceleration in the bore.

The objective of the invention is to create a simple, versatile and low-cost method for combining the functionality of a chilled and pneumatic weapon in sports and gaming weapons, applicable to various designs of sports and gaming weapons.

The technical result when using the invention is the most complete imitation of firing from military small arms when using sports and gaming weapons, which consists in reproducing light and sound effects, recoil, automatic operation by sports and gaming weapons, similar to those that occur when working with military small arms.

The specified technical result is achieved by combining sports and/or gaming weapons with the structural elements of a blanked weapon (barrel, flash-noise cartridge, magazine) in such a way that when throwing an airsoft or pneumatic projectile, light and sound effects, recoil, and automatic operation are reproduced, similar to those that arise when working with military small arms.

The invention is illustrated by a drawing, which does not cover and, moreover, do not limit the entire scope of claims of this technical solution, but is only a special case of implementation.

In FIG. 1 schematically shows a longitudinal section of a weapon, the design of which combines elements of pneumatic and chilled weapons, with a common magazine for flash-noise cartridges and projectiles, and a feed mechanism due to the removal of part of the powder gases: breech, chamber 1, flash-noise cartridge in store 2, flash-noise cartridge in the chamber 3, barrel 4, barrel for throwing a projectile 5, projectile 6, gas exhaust channel for pushing a projectile 7, a common magazine for flash-noise cartridges and projectiles 8, an opening for ejecting a projectile from a magazine 9, a channel for supplying powder gases to the projectile 10.

In FIG. 2 schematically shows a longitudinal section of a weapon, the design of which combines elements of pneumatic and chilled weapons, combined with a Rank-Hilsch vortex tube: breech, chamber 1, flash-noise cartridge in chamber 3, barrel 4, Rank-Hilsch tube body 11, channel for withdrawal parts of powder gases into the Rank-Hilsch tube 12, tangential nozzle 13, conical throttle 14, diaphragm 15, hot gas flow 16, cool gas flow 17.

The way to combine the functionality of the chilled and pneumatic weapons in sports and gaming weapons is as follows.

All structural elements of the blanked weapon (or the weapon itself) are used, which are responsible for firing and supplying flash-noise cartridges.

The implementation of this invention is possible with minimal intervention in the design of the original blanked weapons, which will make it possible to simplify and reduce the cost of production as much as possible.

Throwing projectile 6 is carried out by removing a small part of the powder gases generated when fired with a flash-noise cartridge 3 into a separate barrel for throwing projectile 5, similar to that used in airsoft or pneumatic weapons.

The barrel for projectile 5 can be located next to the main barrel 4, or be inserted inside the main barrel 4. In both cases, the barrel of the blanked weapon remains in a deactivated state.

To hide the barrel for throwing projectile 5, when it is structurally located outside the main barrel 4, you can use one of the options for a long forearm that covers the space from the receiver to the barrel cut.

The removal of part of the powder gases necessary for throwing the projectile 6 is carried out through the gas exhaust channel cut into the barrel 4 for pushing the projectile 7, which passes into the channel for supplying the powder gases to the projectile 10, or through the nozzle on the barrel cut 4 (muzzle brake-compensator or silencer) through a separate tube that replaces the exhaust gases to push the projectile 7.

The diameter of the exhaust gas channel for pushing the projectile 7 and the channel for supplying powder gases to the projectile 10 determines the maximum allowable energy of the projectile.

Flash-noise cartridges 2 are located in a common store for flash-noise cartridges and projectiles 8, the design of which corresponds to the used blanked weapon. The supply of light-noise cartridges 3 into the chamber 1 is carried out as standard for the type of blanked weapon used. Thus, the automation of a chilled weapon will not require additional changes.

Throwable projectiles 6 can be located both in a common store for flash-noise cartridges and projectiles 8, and in a separate store.

When using a common store for flash-noise cartridges and projectiles 8, projectiles 6, in a special bunker, can occupy its front part, which is freed up, because flash-noise cartridges are shorter than combat cartridges by the length of the bullet. The bunker can be both stationary and quick-detachable.

To replace a gas cartridge or gear box, a part of the powder gases generated when firing a flash-noise cartridge is fed directly into the bunker with projectiles through a special channel for removing part of the powder gases 7, which passes into the channel for supplying powder gases to the projectile 10. The missile projectile 6 is sent into the barrel 4, followed by its acceleration in the barrel bore, is carried out due to the energy of a part of the powder gases generated when fired with a flash-noise cartridge, discharged directly into the ball hopper through a special channel for removing part of the powder gases 7, passing into the channel for supply of powder gases to the projectile 10.

Powder gases first enter the channel for removing part of the powder gases 7, then into the channel for supplying powder gases to the projectile 10, and through it they enter directly into the hopper for projectiles, put pressure on the projectile 6 and push it through the hole for ejection of the projectile from the store 9 to the barrel for throwing the projectile 5 with its subsequent acceleration in the channel of the barrel for throwing the projectile.

For correct operation, a snug fit of the magazine to the breech 4 of the barrel is required at the junction of the channel for removing part of the powder gases 7, from the breech side of the barrel 4, and the channel for supplying powder gases to the projectile 10, from the side of the magazine, as well as at the junction a barrel for throwing a projectile 5 with a hole for ejecting a projectile from the magazine 9. Rubber rings can be used as one of the options for sealing elements.

When using projectiles 6, the thermal impact on which leads to their destruction - airsoft balls, lead bullets or balls for pneumatics, it is possible to use a compact vortex gas cooler - a Rank-Hilsch vortex tube, which can be placed both inside and outside the main barrel - in the muzzle nozzle or inside the forearm.

When a weapon is fired, part of the generated powder gases is removed from the bore 4 through a channel for removing part of the powder gases into the Rank-Hilsch tube 12 into the tangentially oriented nozzle 13 of the Rank-Hilsch tube 11. When gas flows through the tangentially directed nozzle 13, an intense peripheral gas is formed. circular flow from left to right. The conical throttle 14, passing only part of the gases from the peripheral layers, contributes to the formation of a paraxial strongly swirling cold vortex flow directed from right to left and exiting in the form of a stream of cooled gases 17 from the diaphragm 15 located at the left end of the Ranque-Hilsch tube. The rest of the peripheral layers flows from left to right, through the conical throttle 14 in the form of a stream of hot gases 16.

The flow of cooled gases is diverted to push and accelerate the projectile without causing its melting/destruction. The flow of hot gases flows out and is no longer used.
