谁能给我 AK 47 的英文介绍

The Avtomat Kalashnikov (shortened from Russian: Автомат Калашникова образца 1947 года, Avtomat Kalashnikova 1947 English) is a gas-operated assault rifle that was used in many Eastern bloc nations during the Cold War. Adopted and standardized in 1947, it was designed by Mikhail Kalashnikov and produced by Russian manufacturer Izhevsk Mechanical Works.
During the Second World War, the Germans developed the concept of the assault rifle. This concept was based on the knowledge that most military engagements in modern warfare were happening at fairly close range with the majority happening within 100 meters (110 yd). The power and range of contemporary rifle cartridges was simply overly powerful for a vast majority of engagements with small arms. As a result, a cartridge and firearm were sought combining the features of a submachine gun (high-capacity magazine and fully-automatic fire capability) with an intermediate-power cartridge that would be effective to a range of 300 meters (330 yd). For the sake of reduced manufacturing costs, this was done by shortening the 7.92 × 57 mm Mauser cartridge case and substituting a lighter bullet to create the 7.92 x 33 mm Kurz.
The resulting Sturmgewehr 44 (StG44) was not the first rifle to use these features; it was preceded by earlier Italian Cei-Rigotti and Russian Fedorov Avtomat designs. The Germans, however, were the first to produce and field a sufficient number of the type to properly evaluate its utility. They fielded the weapon in large numbers against the Russians towards the end of the war and this experience deeply influenced Russian doctrine in the years following the war.
Mikhail Kalashnikov began imagining his weapon while still in the hospital, after being wounded in the Battle of Bryansk. He had been informed that a new weapon was required for the 7.62 x 41mm cartridge developed by Elisarov and Semin in 1943. (The 7.62 x 41 mm cartridge predated the current 7.62 x 39 mm.) Sudayev’s PPS43 submachine gun was preferred to Kalashnikov’s design.
Despite circumstantial evidence, Mikhail Kalashnikov denies that his rifle was based on the German assault rifle. It is best described as a hybrid of several previous innovations. To support his position, the AK- owes more to the M1 Garand Rifle than any German design. The double locking lugs, unlocking raceway, and trigger mechanism are clearly derived from the earlier American design. to the Browning-designed Remington Model 8 rifle.
The genius in the design of the Kalashnikov rifle is in the simplification of those contributing designs and adaptation to mass production. The AK can be seen as a fusion of the best that the M1 Garand offered combined with the best aspects of the StG44 made by the best processes was in the recombination of known elements into a compact, reliable and durable package.
There were many difficulties during the initial phase of production. The first production models had stamped sheet metal receivers. Difficulties were encountered in welding the guide and ejector rails, causing high rejection rates.
Once manufacturing difficulties had been overcome, a redesigned version designated the AKM (M for modernized or upgraded—in Russian: Автомат Калашникова Модернизированный) was introduced in 1959. In most former Eastern Bloc countries, the weapon is known simply as the "Kalashnikov". The photo above at right illustrates the differences between the Type 2 milled receiver and the Type 4 stamped, including the use of rivets rather than welds on the stamped receiver, as well as the placement of a small dimple above the magazine well for stabilization of the magazine.
In 1978, the Soviet Union began replacing their AK-47 and AKM rifles with a newer design, the AK-74. This new rifle and cartridge had only started being exported to eastern European nations when the Soviet Union collapsed, drastically slowing production of this and all other small arms.
The AK is simple, inexpensive to manufacture and easy to clean and maintain. Its ruggedness and reliability are legendary. The large gas piston, generous clearances between moving parts, and tapered cartridge case design allow the gun to endure large amounts of foreign matter and fouling without failing to cycle. This reliability comes at the cost of accuracy, as the looser tolerances do not allow the precision and consistency that are required of more accurate firearms. Reflecting Soviet infantry doctrine of its time, the rifle is meant to be part of massed infantry fire, not long range engagements.
The notched rear tangent iron sight is adjustable, each setting denoting hundreds of meters. The front sight is a post adjustable for elevation in the field. Windage adjustment is done by the armory prior to issue. The battle setting places the round within a few centimeters above or below the point of aim out to approximately 250 meters (275 yd). This "point-blank range" setting allows the shooter to fire the gun at any close target without adjusting the sights. Longer settings are intended for area suppression. These settings mirror the Mosin-Nagant and SKS rifles which the AK-47 replaced. This eased transition and simplified training.
The bore and chamber, as well as the gas piston and the interior of the gas cylinder, are generally chromium-plated. This plating dramatically increases the life of these parts by resisting corrosion and wear. This is particularly important, as most military-production ammunition during the 20th century contained corrosive mercuric salts in the primers, which mandated frequent and thorough cleaning in order to prevent damage. Chrome plating of critical parts is now common on many modern military weapons.
To fire, the operator inserts a loaded magazine, moves the selector lever to the lowest position, pulls back and releases the charging handle, aims, and then pulls the trigger. In this setting, the gun fires only once (semi-automatic), requiring the trigger to be released and depressed again for the next shot. With the selector in the middle position (full-automatic), the rifle continues to fire, automatically cycling fresh rounds into the chamber, until the magazine is exhausted or pressure is released from the trigger. As each bullet travels through the barrel, a portion of the gases expanding behind it is diverted into the gas tube above the barrel, where it impacts the gas piston. The piston, in turn, is driven backward, pushing the bolt carrier, which causes the bolt to move backwards, ejecting the spent round, and chambering a new round when the recoil spring pushes it back.
Dismantling the rifle involves the operator depressing the magazine catch and removing the magazine. The charging handle is pulled to the rear and the operator inspects the chamber to verify the gun is unloaded. The operator presses forward on the retainer button at the rear of the receiver cover while simultaneously lifting up on the rear of the cover to remove it. The operator then pushes the spring assembly forward and lifts it from its raceway, withdrawing it out of the bolt carrier and to the rear. The operator must then pull the carrier assembly all the way to the rear, lift it, and then pull it away. The operator removes the bolt by pushing it to the rear of the bolt carrier; rotating the bolt so the camming lug clears the raceway on the underside of the bolt carrier and then pulls it forward and free. When cleaning, the operator will pay special attention to the barrel, bolt face, and gas piston, then oil lightly and reassemble.
The standard AK-47 or AKM fires a 7.62 × 39 mm round with a muzzle velocity of 710 metres per second (2,329 ft/s). Muzzle energy is 1,990 joules (1,467 ft·lbf). Cartridge case length is 38.6 millimetres (1.5 in), weight is 18.21 grams (281.0 gr). Projectile weight is normally 8 grams (123 gr). The AK-47 and AKM, with the 7.62 × 39 mm cartridge, have a maximum effective range of around 300 meters (330 yd). For comparison, the 7.62 × 54 mm R cartridge has a projectile of 9.6–12 grams (148–185 gr), depending on the weapon, at a velocity of 818 metres per second (2,683 ft/s) for approximately 4,000 joules (2,950 ft·lbf) of energy.

In 1978, the Soviet Union began replacing their AK-47 and AKM rifles with a newer design, the AK-74. This new rifle and cartridge had only started being exported to eastern European nations when the Soviet Union collapsed, drastically slowing production of this and all other small arms.
During the Cold War, the Soviet Union, Communist China and the United States supplied arms and technical knowledge to numerous client-state countries and rebel forces to promote their interests. This period saw the proliferation, sometimes free of charge, of AK-47s by the Soviet Union and Communist China to pro-communist countries and groups such as the Nicaraguan Sandinistas and Vietcong. The AK design was spread to a total of 55 national armies.
The proliferation of this weapon is reflected by more than just numbers. The AK is included in the flag of Mozambique and its coat of arms. It is also found in the revolution era coat of arms of Burkina Faso, the flag of Hezbollah, and logo of the Iranian Islamic Revolutionary Guards Corps. "Kalash", a shortened form of "Kalashnikov", is used as a name for boys in some African countries.
In the U.S., movie makers often arm criminals, gang members and terrorist characters with AK’s. However, not all influences of the AK have been violent. In 2006, Colombian musician and peace activist César López devised the escopetarra, an AK converted into a guitar. One sold for US$17,000 in a fundraiser held to benefit the victims of anti-personnel mines, while another was exhibited at the United Nations’ Conference on Disarmament.
