WO1998045660A1 - Gun barrel for bullets or projectiles provided with an obturation belt - Google Patents

Abstract

The invention relates to a threaded fire weapon, and especially to barrels for shooting bullets or projectiles provided with an obturation belt. The inventive barrel enables the initial speed of the bullet or projectile to be increased and, consequently, the distance covered by and the flight of the bullet or projectile to be extended, the influence of the barrel heat on the shot quality, the recoil stroke, the noise and the flash at the starting shot and the barrel wear (erosion) to be reduced. The inventive barrel can be used in virtually all known fire weapon systems with interchangeable barrel. Its use improves the shot quality with no increase of the weapon mass and size. Barrels having a flat portion with varying shrinking limits can be used to develop multicaliber systems for one single type of ammunition, thereby extending significantly the tactical and technical features of the weapon as well as its application range. The fire weapon barrel has a threaded portion (1), a flat portion (2) and a chamber (3).

Description

 Set up a bulletproof guns for bullets or shells with a bullet gun

Area of technology

The invention is supplied to the out-of-body guns, in particular, to the bullet or bullet-guarding systems for shelling with a bulletproof gun.

PREVIOUS LEVEL OF TECHNOLOGY

The condition of the farm equipment containing the camera and the main part, formed by the cuts, which perform the functions of the gas distribution channels, and the ends of the distribution of goods, is known.

10 parts of the projectile [1]. The cost of such a supply is reasonably high due to the complexity of cutting.

The closest to the claimed technical substance is the equipment for shooting bullets with bullets or shells with a bullet, which is loose

15 connected smooth part, tapering partly on the part of the external part [2]. The well-known regime does not ensure the sufficient high initial velocity of bullets or shells and, consequently, the long-range of weapons.

Disposal of the invention 0 The technical result of the use of the proposed invention is included in the increase in the initial speed of the bullet or the projectile and, as a result, the result is increased.

Quick description of the drawing of FIG. 5 In FIG. 1, a separate illustration is shown after the device has been disconnected, in FIG. 2 - bullet with an outgoing explanation.

The barrel of the armament is made up of the outer part 1, smooth part 2 and the part 3.

Bullet 4 was captured in the final paragraph 5. 0 The best embodiment of the invention

The length of the smooth part 2 of the rule is from 1 to 30% of the total length of the forelock 1 and 2 smooth 2 parts of the system allows you to reduce the effect of heating the steel on the quality of the shot, reduce the output, sound and the sound when the gun is hot, save it (exhaust).

The optimum is the smooth part of 2 conditions in the form of a truncated cone

5 or slightly bent at a length of about 20 to 25% of the total length of the cut 1 and smooth 2 parts of the body.

With a shorter length of smooth part 2, a delay of entering the bullet 4 into the outside part of the channel is possible, which is suitable for the detachment of the charge.

10 At a greater length of smooth part 2, an increased vibration of the steel is observed, which results in a sharp ejection.

The result of narrowing of smooth part 2 of the rule in the direction of movement of the bullet 4 is that its other part 5 is crushed, due to which the control of the bullet 4 on the channel of rest is stopped. This increases pressure in the

On the 15th channel of the control and intensification of the burning of a charge, which, in turn, increases the pressure in the channel of pressure, in turn. Otherwise, there is a 5-way exhaust gas outlet, which allows the pressure to be removed from the overtake Уля The result of the bullet 4 is high

20 initial speed of movement. The center of the bullet 4 in the outer part of 1 st of service is the main part and the body of the bullet, which corresponds to the caliber of the cease-fire.

Intended use

Failure has been made to use practically all the well-known systems of 25 non-operative armaments with removable arms. Its use entails an increase in combat power without increasing the weight and size of the guns.
