KR20090087161A - The warhead without the steel wire - Google Patents

Abstract

A gun not having a steel wire(twist groove) is provided to increase the shooting range by finishing the inside in a flat cylindrical type, and improve the accuracy when hitting on the target by suppressing the increase of centrifugal force. Inside a gun barrel of a cannon, a steel wire of the inner part(b) of a battery line is removed to prevent a warhead from being rotated. The inner part of the gun barrel is finished in a flat cylindrical shape. By removing the steel wire of the gunbarrel which induces the rotation of the warhead, the direct-property of the warhead is enhanced.

Description

Guns without a twisted groove {the warhead without the steel wire}

The present invention relates to the inner surface of the barrel which the warhead is fired from the gun, and particularly to the inner surface of the barrel which has been processed into a flat circle (b) to prevent rotation of the warhead.

In general, gun guns manufactured for horse killing have increased the function of killing by forming a plurality of steel wires (twist grooves) on the inner surface of the barrel to increase the killing function, thereby giving rotational force to warheads passing through the barrel.

Steel wire (c) is classified into four tanks first and six tanks first according to the installation type, four tanks first is configured to rotate the four steel wires to the right, six tanks first is configured to rotate the six steel wires to the right will be.

As such, when the warhead passing through the barrel is rotated by the steel wire (c), the warhead continues to rotate while passing through the target (g), which causes severe damage to the target. However, the rotation of the warhead by the steel wire can increase the ability to kill horses, but inversely, there is a problem of shortening the effective range of the warhead and reducing the accuracy of the gun.

In other words, when the projected warhead rotates, the warhead proceeds in an increasingly large concentric circle due to the rotational centrifugal force (FIGS. 4 and 5), resulting in a lot of air resistance, which shortens the effective range of the gun and decreases the accuracy. do. For reference, the effective range of the M16 rifle was limited to 460M, and that of the K1 and K2 rifle was 400M.

The steel wire (c) also causes the gun fire to be overheated by inducing a strong friction with the barrel in the process of converting the gunpowder gas into a curve, while reducing the explosive force of the gunpowder gas.

As above, the performance of the gun is determined in relation to the internal structure of the barrel.

Due to the rotation (g) of warheads fired from guns, the reduction of the range and the inaccuracy are solved through the improvement of the internal structure of the barrel.

4 and 5 show that a warhead fired from a conventional steel wire gun, M16, K1, K2 rifle, etc. is flying. The greater the rotational force, the faster the concentric circles (g) become. These concentric warheads are subject to a lot of air resistance, leading to a reduction in range and inaccurate deviation from the target.

The rotation of the warhead generates a large centrifugal force in proportion to the rotational force, so that the warhead moves away from the center of the barrel, that is, the center of the target (FIGS. 4 and 5).

In the present invention, by improving the structure of the inner surface of the barrel from a steel wire (twisted groove) to planar shape to solve the problems of the conventional gun gun (Fig. 1).

In other words, the rotational force of the warhead is reduced by converting the internal structure of the barrel from the uneven structure with the wire to the planar structure. The dissipation of rotational force increases the range by reducing the air resistance of the warhead and increases the accuracy by weakening the rotational centrifugal force.

Rifles without a twisted wire on the inside of the barrel will reduce production and reduce production prices due to material savings. As the production cost is more economic than the conventional barrels and shells of the past, it is expected to be applied to all barrels and shells gradually. The fabrication process can also omit the twisted wire process from the current shell and barrel production process.

As there is no groove on the inside of the barrel, the strength of the barrel will increase and the thickness of the barrel will be thinner, and the weight reduction will help soldiers perform their duties.

Barrels without wires will stabilize warhead flight, resulting in greater range and increased accuracy. This accuracy can be used primarily for warheads of guns used by police officers to reduce unnecessary civil damage and punish only criminals, and also benefit soldiers as their effective range increases.

As well as the M16 and AK47 rifles that are currently used around the world, they can be easily applied to K1 and K2, the main weapons of the Korean military.

In particular, firearms that fire warheads of larger size than anti-aircraft guns are not a substitute, so there is no need to rotate the warhead to make a large wound. In particular, in the case of the cannon, the power is not increased or decreased by the rotational force, but the power is determined by the gunpowder, so the replacement is expected in the bursting method without the steel wire (twist groove) of the present invention.

The present invention provides a rifle and cannon with an improved structure to eliminate the rotation of the warhead and enhance the direct propensity by removing the barrel (twist groove) of the barrel or barrel that induces warhead rotation and maintains the cylindrical inner surface (b). It relates to the internal structure of the barrel containing (Fig. 1).

In gun barrels or barrels, the twisted grooves cause the gunpowder gas to rotate on the sides of the warhead and exert a force on the warhead, causing a rotational force (g) in the warhead. The rotation of the warhead is caused by artificially creating a steel wire (c) in the barrel or barrel.

Warheads fired from almost all barrels or barrels with current steel wires will rotate forward and form a spiral flight (f, g). Helical flight suffers from air resistance, which reduces its effective range and moves away from the center of the target, resulting in inaccuracies.

4 and 5 are warheads, such as the rifle M16, AK47, K1, K2 with a steel wire is flying. Because of the resistance of air, the range is shortened and accuracy is low. Because of the low accuracy, it can cause accidental accidents when used as a police rifle, and it is difficult to use it as a warning or check in peace because the degree of injury is too large.

On the other hand, the flat cylindrical barrel without the steel wire (twist groove) only pushes the warhead in a straight line, so the rotational force of the warhead will be minimal or undetectable. Since the rotational force is insignificant, the warhead's flight does not rotate about the barrel axis as shown in Figs.

The warhead is precisely aimed at the target, reducing unnecessary casualties, and since the warhead does not rotate, the affected area is smaller, making it ideal for peacetime rifles.

In addition, the gunpowder gas is released in the same direction as the explosion direction, the frictional heat with the barrel is reduced to reduce the overheating of the gun.

Modern warfare is determined by large weapons, including long-range missiles, rather than direct combat between soldiers with guns. Rifles are positioned for vigilance, so you need an accurate firearm rather than hurt your opponent.

Non-rotating warheads have smaller injuries than rotating warheads, even when a person is hit. You will lose a lot of combat power, but the affected area does not grow beyond the size of the warhead. Occasionally, you may be able to improve to the condition before your injury. It is advisable for police officers who do not have to kill their opponents, or for soldiers who work mostly on the border, not in peacetime combat.

The defense power of modern nations is determined by the ownership of strategic missiles. Rifleless rifle is suitable for modern society in the 2000s, which is using missile-based defense policy. Hyundai is a large missile defense era, a strategic weapon. Already in Europe, most of the conventional weapons have been scrapped because of the potential for human combat. Therefore, a rifle without a liner with a lighter degree of injury is preferable to a seriously injured rifle.
