Rifling tube in the role of industry
Neckline also known as the rifling line, the gun chamber is a spiral mountain convex line, the part of the mountain is called the negative rifling line, the raised part is called the yang film line, the rifling line's role is to make the warhead rotating movement, in order to maintain the flight stability, to improve the hitting accuracy and increase penetration, the Chinese army's existing weapons rifling line are There are spinning lines.
Rifling principle of the rifling gun principle is not complicated, when the bullet in the gunpowder gas role embedded in the rifling, it will be along the rifling forward movement, at the same time began to rotate, travel turn of the cartridge and gyroscope similar to the bullet axis is equivalent to the dry gyroscope axis, the tangent line of the ballistic path, i.e., the direction of flight of the bullet away from the muzzle is equivalent to the dry vertical axis, the bullet rotation speed of 3,000 revolutions per second, which not only does a circle around the head motion .
The eye of the bullet's axis is always around the tangent line of the ballistic trajectory to do conical movement, so that can overcome the air resistance to gas, and constantly fly forward to ensure that the bullet is stable forward flight, therefore, a small bullet can fly thousands of meters of distance, the reason is not difficult to understand.
The rifling of the number of strips of how many often with the size of the gun caliber, generally between 3 to 12, pistols, sub-machine guns, rifles, etc., often 4, caliber of the machine gun is 8, the direction of the rifling of the right and the left two categories, are now generally used in the right-hand rotation, the reason for this, but it is only customary, rifling, the bullet head away from the muzzle of the rotational speed of up to rotate 200,000 revolutions per minute! The bullet head can be rotated as fast as 200,000 revolutions per minute when it leaves the muzzle, which ensures enough flight stability to guarantee the flight of the bullet.
