HU227997B1 - Gas-expansion chamber for fire-arm having longer barrel and increased propellant charge - Google Patents

Abstract

The firearm with pressure accumulator (5) having increased battering charge (3) and barrel (1) length has a piston (43) sliding in the accumulator housing (41) fixed to the breech (6) and springs (38, 38, 40 supporting said piston. To create a pneumatic spring (17) an annular brake chamber (44) is provided. The battering-charge is arranged in the bolt body (31) located in the breech and has a neck (7) with an opening (9) facing towards the barrel to direct propellant gas to the barrel. This structure can be adapted to any size of the firearms, e.g. sharpshooter rifles with range of 4 to 6 kilometres, sky sweepers with an amplitude of 30 to 35 kilometres to combat targets by homing missiles as well as intercontinental missiles with a range of 500 to 1000 kilometres.

Description

FIELD OF THE INVENTION The present invention relates to a shotgun weapon. which eliminates the fundamentally beneficial properties of known and contracted firearms, and combines and enhances its fundamentally beneficial properties.

The barreled firearms, hitherto used in the barrel, have uneven pressures of propellant gases. At the beginning of the tube & pressure rises sharply, wximum, then decreases continuously. Known and economically acceptable pipe materials neffl allow the maximum vapor pressure in the pipe® to exceed 3OOG-4GQ0 bar. Because of the pressure drop in the distal section of the tube, it is not meaningful to use a tube longer than the diameter of the tube (so-called caliber) - 50 ~ 60 ~, because the longitudinal pressure of the longer tube causes the projectile to brake forces go into eulsul and thus slow down the projectile instead of accelerating ..

As a result of this limitation, the projectile discharges from the barrel of conventional firearms at a maximum mouth rate of 1-1.6 tes / sec.

Developed in the 1960s in the United States® under the h & RP program (bigh Alfcifcude Research Projecckt) 2.5-3 is now available with the guide shoe solution. tes / sec estuary velocity by firing undersized projectiles through large corners of high-velocity cannon. With this solution, the weight of the projectile was reduced to 1 / 3-1 / 4 of that of the full-size projectile, meaning that its sons brought about 3-4 times the propelling force per unit projectile. ISO-SQÖ times the bullet penetrating yen <This solution has become widespread and is commonly used in combat weapon guns in advanced countries, '* ♦ * - * »♦ * χ. ψ

A big flaw in this solution is that the propellant gases are uneven, yet expensive and difficult to maneuver due to the extremely large size and self-weight of the gun above the cavity. part of the digestive tract is digested ♦

The problem is solved by solving the above problems in that most of the gas produced when the charge of a heavily increased powder powder is burned is a suitably designed clamping battery; and the smaller part: flowing into the tube of very increased length and propelling the projectile, and then, when the projectile advances in the event of heavy rainfall, the gases accumulating in the lumen tube flow into the tube and close to the entire length of the tube propelling the projectile under even pressure.

Thus, the present invention is a pressurized firearm having a well-increased powder port compared to the known conventional firearm and also having a barrel with a substantially increased length. it has an actuator piston supported by superimposed springs and a gas boom that reduces spring stroke.

There are many solutions in the literature, such as 384-59? French Patent No. 1895719, U.S. Pat. U.S. Patent No. 32,612,664; and French Patent No. 2466740, in which a portion of a propellant is propelled by a small fraction of its propellant propellant gas and causes the weapon to be refilled automatically and to distribute a series of shots. However, in these solutions, the amount of gas discharged and therefore the firing range of the firearm is reduced. However, for this solution, the firearm barrel is provided with a lateral bore or bores for gas removal, which reduces the barrel's rigidity, just as the barrel's rigidity is reduced by its uneven, stepped opening, but, on the contrary, you came up with this solution. in order to achieve the desired service life of the firearm, the amount of gunpowder must be reduced, which also results in a reduction in firing distance. Also with these. In the case of mg solutions, due to the low value of the shotgun, the length of the barrel is not raised, which would be an essential requirement for increasing the distance of the shoot.

Detailed Description of the Invention The present invention will be described in detail with reference to the drawings, in which the conceptual advantages over firearms treated as a pre-horse are illustrated in Figures 1 and 2, and specific embodiments are shown in Figures 3, 4, 5, 6, 7 and 8. .

Figure 1 a. Variant 5 of the present invention illustrates a conventional firearm, in which the firing powder 3 in the barrel is accelerated and the projectile 2 is accelerated directly by the barrel.

Fig. 1, version b, illustrates a guide-line solution developed in the context of the UHP program, in which the guns of the gunpowder 3 advance the projectile 2 by inserting a guide sleeve 4 in the barrel 1. A striking feature of this solution is the excessively large size of the powder cartridges 3 relative to the projectile 2. It will be appreciated that this solution will result in at least a desire to weave an amount of gunpowder by killing the propellant energy capable of delivering approximately double estuary velocity. Also striking in this solution is the large borehole of the tube 1 relative to the projectile 2, which, before being further increased, may be determined by the rapid increase in the strength of the guide shafts.

For the 1st hunger e. version. illustrates the novel firearm solution of the present invention. What is striking about this is: scál is> or: et izezinized four hv? 'V. This is an increased amount of gunpowder it.vs.sclj v. the estuary speed above 2 km / ssc achieved by this solution. The increased amount of sponge gas in this solution directly accelerates the projectile 2, i.e., no significant losses are associated with the use of the ί guide shoe. The caliber of the rain 1 corresponds, as in the conventional solution, to the projectile size of the bullet 2, i.e., it is not necessary to use a heavy mass, which is difficult to move, and of a raised caliber 1. In order to prevent the guns from being lifted by the increased amount of powder powder, this is ensured by the battery 5. Namely, the squeezer press 5 also burns the excess gas carbon in the first half of the rain 1 and feeds it back into the tube 1. The work of the whole gas can be ensured by applying a strongly increased tube length according to this wall. solves the problem with maximum pipe lengths of 250-300 caliber.

The energy ratios of the three versions shown in Figure 1 are plotted against each other in the diagrams in Figure 2,

That. curve can be seen in the tube of known firearm solutions. first increasing gas pressure on sparrows, then decreasing significantly. The same applies to b. also the gas pressure of the guide shoe shown in the curve, with the difference that the corresponding values would be significantly extended according to the larger caliber used. The curve solution c of the present invention exceeds the value limited by the strength of its even longitudinal bar, but its sub-name is the size of the long, uniform work area that compares with the increased caliber of work of the guidewire solution. and even overstates it with some value.

The latching device shown in Figure 3 has a defect. On the one hand, because of the annular nature of the annular piston 10, it needs to be sealed from the inside and the outside by the .12 and 2.1 seals. Double sealing is less effective. On the other hand, the annular piston 10 encapsulates a cartridge of cartridge 3 and does not allow it to be dispensed from the loose side. dosing ammunition, which. makes high-speed dosing difficult.

This Remedy bta - ^; 1 Yx U-hs Fig. 5:? Er'Mti: si «.w: ··, ·« e 1y using relatively large diameter 33.39.40 springs placed in one piece Time to maintain sufficient spring force. This solver has the same basic function as the previous one, but it makes a difference if the guns created by firing the 3 gunpowder cartridges would leave the closed body 31 through the neck 7 and the pointer 9 towards the% 1 tube and the gauze bow hole 42 to the 6 tube backs from behind AM battery? tordugattyuí; the rear is provided with springs 38,39,40, which are preferably opposed to the spiral, while the gas cushion 17 which is locked into the annular braking chamber 44 protects against a metallic semi-collision when the battery piston 43 advances,

The solution of FIG. 6 is capable of providing even greater thrust through the design of an open-ended battery, while the open design of the battery 43; the movement of tordug & btyu is considered accessible for feeding or other activities,

It is to be understood that, due to the principle of operation of the pressure accumulator gun according to the invention, it can also be operated without sulfuric power. This fact positively influences both the knight's manufacturing cost, horsepower and firepower; recommends. Usually activities related to back-sliding the pipe, such as: fed to the invention in other ways: electromagnetic, electro-pneumatic, etc. ways to solve it. With the solution shown in Fig. 6, this task can also be mechanically solved by the movement of the battery piston 4.3.

8, the resulting powder particles 8 are drawn to the tube 1 and the barrel to the actuator piston 43. The tube 1 is secured to the front end of the tube tail 6 while the accumulator pump 43 extends into the cylindrical space at its rear end. into it. the 45-pin end of the battery-shaped 43 plate accumulates in a strong one-handed design. ranked 38.39 springs, 38.39 springs are purposefully opposite spiral .. The 38.39 springs rest on 47 support plates at their opposite ends, which is 4? the support plate is secured to the tube boss 8 by means of the locking nuts 49 through the kotorudekou 48. From this embodiment it is evident that a. The size of springs 33-39 of the present invention can be increased at stake vines.

These springs can be made of special steel materials and various fiber-reinforced plastics.

To overcome these drawbacks, ·· -ved writes in Fig. 7 and Fig. 8, using various flexible gas media as springs,

Fig. 7 is filled by the gases formed by the firing of the powder charge 50 in the closed body 19. cylinder II roof. This 500-1000 bar cut-out gauze pre-stretches the Akkias submersible plunger 13. The vapor pressure of the 3GOO-6OOO bar, produced by the 3 gunpowder, lasts for a lifetime of the accumulator piston 43 and maintains pressure with cylinder II. This equilibrium results in a relatively uniform gauze pressure in the tube 1 which is long-drawn. When the bullet 2 leaves the tube 1, the pressure in the cylinder II pushes the battery piston 43 forward. The brake pin 35 in the aaon closes the gauze bore 42 and thus. 43 akkbnitdótordugatfyu brakes without metal collision,

The design of Fig. 8 is much the same as the previous one, except that cylinder II pressure is exerted on the gas connection 52 and valve 51 by the inlet gas. Λ the gas introduced can be either a high pressure neutral gas such as nitrogen or air or a flammable gas eg. acetylene, which is burned in cylinder II and thus produces the required vapor pressure.

The advantages of the novel air solution according to the invention are summarized below.

The main advantage of the present invention is that, when a sufficiently large powder charge and a long barrel length are used, the mouth velocity of the firearm according to the clown ratio can significantly exceed the highest mouth velocity achievable with known firearms.

Another great advantage of the present invention is negoldum. because of its fast burning, high tensile strength, and the use of bryozone powder powders without damaging the tube.

Another advantage is that it is able to withstand smooth, smooth acceleration in the barrel without detonation of the explosive material in the bullet and without damage to the projectile and shocks sensitive to shocks, particularly in the case of self-propelled rocket launches.

It is also advantageous that the impact of the projectile is significantly reduced when the projectile is fired, and moreover, by favorably selecting the proportion of swing masses, the projectile can be practically eliminated.

The invention can lead to advancement in almost all the ranges of firearms. far-barrel sniper, with a range of 4-6 km at snares, can be used on aerial machine guns to target targets at 30-35 km height with self-guided missile projectiles and can be used for very large intercontinental guns at ranges of 500-1000 km,

The development of the pressure throat in accordance with the present invention is not only an enhancement of the firing range
