Abstract

The utility model relates to a tiny recoil force gun muzzle brake which belongs to a gun muzzle brake, in particular to a tiny recoil force gun muzzle brake of the artillery with large caliber. The utility model solves the problems of low shooting speed and large recoil force of the prior artilleries. The utility model has the technical proposal that a guiding rail is fixed in the out shell of the brake along the direction on a gun tube. The brake is divided into two air chambers which are air chamber 1 and air chamber 2 by an air blocking stable ring along the radial direction. By adopting the structure in the utility model, the recoil force of the artillery is greatly reduced, the length of the brake is similar with the South African New Nobility (155 mm 52 diameter), and the braking rate can reach 75 percent to 85 percent. Compared with the soft recoil mechanism, the utility model has the advantages of simple structure, convenient manufacture and reliable safety. Because the recoil force is greatly reduced by using the utility model, the artillery with large caliber can be arranged on jeeps, armored vehicles, airplanes and patrol boats, etc.

Description

Little recoil muzzle brake

Technical field

The utility model relates to a kind of muzzle brake, relates to a kind of muzzle brake of large caliber gun recoil specifically.

Background technology

Cannon, the weapons that this is the most ancient, in the past, in the present and the future's the war, all will be violent with its firepower, power is big, precision good, mobility strong, numerous advantage such as far firing range, price are low, the woods of standing erect at weapon, along with technological progress, gun launched missile and big gun are penetrated the appearance of very-long-range ammunition and have been consolidated this status more.World's name big gun of 2006 5 phases " ordnance knowledge ", 8～10/minute of the German P2H2000 carriage motor howitzer maximum rates of fire.Certainly walk 3/minute of big gun sustained rates, be the raising of what cause influence firing rate so for Chinese novel 155 millimeters of 2006 2 phases " ordnance knowledge "? except shell weighs, loads the inconvenience, recoil is too greatly the main cause that the restriction firing rate improves.As U.S.'s soft-recoil gun of 1998 1 phases " ordnance knowledge ", common 105 millimeters howitzer kicks surpass 7 tons, and soft-recoil gun is but less than 2.1 tons, and 6～8/minute of common big gun firing rates, soft-recoil gun can reach 20/minute.

Summary of the invention

The purpose of this utility model is at above-mentioned recoil problem, and provides a kind of system rate of moving back to increase substantially, and has simple in structurely, easily manufactured, safe and reliable, does not have little recoil muzzle brake of failure problems.

The technical solution of the utility model is: at gun tube upper edge axial restraint guide rail is arranged in the muzzle brake shell, radially muzzle brake is divided into two air chambers of I, II by retaining gas stabilization ring.

Said guide rail has 4 in the technical solutions of the utility model, and the cross section of every guide rail is trapezoidal, and guide rail passes from powder gases restriction tube.

Be fixed with the guide rail stable ferrule on said 4 guide rails in the technical solutions of the utility model.

Be fixed with deflector on the said muzzle brake shell in the technical solutions of the utility model.

Said deflector has 6 pairs in the technical solutions of the utility model, and the symmetry that recedes is fixed on the both sides of muzzle brake shell.

The utility model is to make according to high pressure powder gases expansion diffusion principle, high pressure gunpowder gas flow will spread in the middle of the muzzle brake time, adding gunpowder gas restriction tube again stops again and limits some and get off, in barrier gas, also stopped the burr that does not fall on the bearing band, at this moment guide rail can make bullet continue to penetrate along heading, and the precision of shooting can be affected; Barrel of the present utility model, guide rail, retaining gas stabilization ring and powder gases restriction tube are an integral body, they can spread powder gases fully, also can stop, limit powder gases, can also guarantee fire accuracy, the muzzle brake shell can concentrated vectoring the gas outflow that recedes from both sides, thereby the reaction force that produces when offsetting the cannon emission reduces recoil; The utility model is compared equal in length with the muzzle brake of the 155 millimeters 52 times of bores in South Africa, and the system rate of moving back will reach 75～85%, compare with soft-recoil gun, have simple in structurely, easily manufactured, safe and reliable, not have failure problems; The utility model can make the cannon of larger caliber bring up to jeep, panzer, aircraft, guard boat etc. owing to reduced recoil widely, to improving the fighting capacity of army, will play very big impetus.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right diagrammatic sketch of Fig. 1.

The specific embodiment

As shown in Figure 1, 2, with 155 millimeters bore cannons is example, when processing barrel 7 gun tubes, at gun muzzle 52 equimultiple bore places, stay 4 guide rails 3 vertically, 377 millimeters of guide rail 3 length, it is trapezoidal that its cross section all is, and stays a retaining gas stabilization ring 2 afterwards, thickness is 12 millimeters, after crossing retaining gas stabilization ring 2, stay 4 cross sections to be trapezoidal guide rail 3, again through to outlet, stay the powder gases restriction tube 5 of one section 50 millimeters long in the exit, guide rail 3 passes from powder gases restriction tube 5, and powder gases restriction tube 5 thickness are since 4 millimeters, and are neat with guide rail 3 gradually; The shell 1 of muzzle brake is enclosed within on guide rail 3 and the powder gases restriction tube 5, and the centre snaps in retaining gas stabilization ring 2, and retaining gas stabilization ring 2 radially is divided into muzzle brake two air chambers of I, II; The outlet of muzzle brake shell 1 is neat with powder gases restriction tube 5, is enclosed within on the powder gases restriction tube 5; Muzzle brake shell 1 left end is enclosed within on the gun tube of barrel 7, there is the exhausting window of 6 symmetries muzzle brake shell 1 both sides, 6 sweptback deflectors 4 of symmetry are on the guide rail 3, in the middle of the I, II 2 air chambers, respectively have a stable ferrule 6, stay during processing guide rail 3, retaining gas stabilization ring 2 and the equal car of powder gases restriction tube 5 inner faces go 1 millimeter, and muzzle brake length begins to be 775 millimeters together to muzzle brake shell 1 from gun muzzle, 4 guide rails 3, the smooth bore big gun is retained straight, the retained the same angle of rifle cannon with rifling around; After muzzle brake is made above-mentioned shape, if it is too high that system is moved back rate, powder gases restriction tube 5 can be removed, as remove powder gases and limit tube 5, connection is this problem that is related to the stable problem of guide rail again and stops powder gases with guide rail, and inconvenience is here spoken more, and the angle of deflector 4 on the muzzle brake shell 1 and barrel 7 axis is when 90 spend, can increase the stability of shooting, 45 can reduce recoil when spending to greatest extent.
