谁能给我 AK 47 的英文介绍
During the Second World War, the Germans developed the concept of the assault rifle.[citation needed] 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.[4] This is not surprising as millions of Garand rifles had operated reliably in combat around the globe. The safety is surprisingly similar[5] 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.[6]
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.[7] Instead of halting production, a heavy machined receiver was substituted for the sheet metal receiver.[8] This was a more costly process, but the use of machined receivers accelerated production as tooling and labor for the earlier Mosin-Nagant rifle's machined receiver were easily adapted. Partly because of these problems, the Soviets were not able to distribute large numbers of the new rifle to soldiers until 1956. During this time, production of the interim SKS rifle continued.[9]
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.[10] This new model used a stamped sheet metal receiver and featured a slanted muzzle brake on the end of the barrel to compensate for muzzle rise under recoil. In addition, a hammer retarder was added to prevent the weapon from firing out of battery (without the bolt being fully closed), during rapid or automatic fire.[11] This is also sometimes referred to as a "cyclic rate reducer", or simply "rate reducer", as it also has the effect of reducing the number of rounds fired per minute during automatic fire. It was also lighter than the previous model, roughly two-thirds of the weight.[12] Both licensed and unlicensed production of the Kalashnikov weapons abroad were almost exclusively of the AKM, partially due to the much easier production of the stamped receiver. This model is the most commonly encountered, having been produced in much greater quantities. All rifles based on the Kalashnikov design are frequently referred to as AK-47s in the West, although this is only correct when applied to rifles based on the original 3 receiver types.[13] 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.[14] 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.[15]
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.[15]
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.[16]

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.[26]
The original AK was also known as the AK-47. It was a gas-operated, selective-fire weapon. Like all 7.62-mm Kalashnikov assault rifles, it fired the Soviet 7.62 x 39-mm M1943 round and used a standard 30-round curved box magazine. The AK came in two versions: one with a fixed wooden stock, and another, the AKS, with a folding metal stock issued primarily to parachutist and armor troops. Except for the differences in the stock and the lack of a tool kit with the AKS, the two version were identical. The early AKs had no bayonet, but the version with the fixed wooden stock later mounted a detachable knife bayonet.
The improved model, known as the AKM, is easier to produce and operate. It weighs about one kilogram less than the AK. The reduced weight results from using thinner, stamped sheet metal parts rather than machined, forged steel; laminated wood rather than solid wood in the hand guard, forearm, pistol grip, and buttstock; and new lightweight aluminum and plastic magazines. Other improvements include a straighter stock for better control; an improved gas cylinder; a rate-of-fire control alongside the trigger; a rear sight graduated to 1,000 meters rather than 800 meters; and a greatly improved, detachable bayonet.
The AKM also has a folding-stock version, designated AKMS, intended for use by riflemen in armored infantry combat vehicles such as the BMP. Except for its T-shaped, stamped-metal, folding buttstock, the AKMS is identical to the AKM. The folding-stock model can reduce its length from 868 to 699 millimeters.
The safety lever serves two functions when in the upper or "safe" position. First, it blocks dirt from entering the action by covering the slot the bolt carrier lever moves through when the weapon is fired. This also prevents the weapon from being cocked while on "safe".
Second, an extension on the pin holding the lever through the receiver blocks the rear of the trigger, preventing the trigger from being pulled. When the safety lever is moved to "fire, the action may be cycled, and the trigger is the only thing holding the hammer from falling.
When the trigger is pulled, the hammer falls, hits the rear of the firing pin, and the round detonates. Note that the AK-47 bolt is locked closed by rotating when the bolt carrier is moved forward (there is a cam on the top of the bolt that engages a slot in the bolt carrier to accomplish the rotation). The firing pin is free-floating -- there is no spring to hold it retracted until the hammer falls. Consequently, if one manually cycles live rounds through the AK-47, one will observe light indentations on the primers where the firing pit hit against them as the action closed. Consequently, it is inadvisable to chamber live rounds unless you are prepared for the possibility of the weapon firing when you do so.
Slam-fires do not seem to be as common as with the SKS, and it is hard to get enough dirt into the action to cause it to malfunction for that reason. I recall one report of flawless functioning even when the rifle was so covered in mud as to be hardly recognizable as a firearm.
The action is gas-operated: when a round detonates, some gas from the explosion is vented out of a small hole at the top of the barrel near the muzzle. This gas pushes against the front of the piston in the gas tube, which is connected to the bolt carrier. As the bolt carrier is pushed rearward by the gas, the bolt rotates to unlock and moves rearward, and the round in the chamber is extracted and pulled back.
The round is ejected when it hits against a small protrusion on the left side of the receiver as the bolt moves rearward. Simultaneously, the back of the bolt pushes the hammer back and cocks it.
The hammer is held back by the disconnect or (the trigger is almost certainly still pulled, since the action cycles much faster than the operator can release the trigger). The bolt and bolt carrier recoil against the recoil spring and guide rod, and come back forward. As the bolt comes forward, it grabs the top round from the magazine and puts it in the chamber.
There is no feature to hold the bolt open after the last round is fired from the magazine. When the operator releases the trigger, the disconnect or moves rearward and releases the hammer to move about 1/8", at which point it is stopped by the (now released) trigger until the operator pulls the trigger a second time.
In 1990 the Army was equipped with the modernized Kalashnikov submachine gun AK-74M, having folding plastic butt with the accessory placed in it and a plate for mounting optical and night sights.
In 1991 the same modernization was carried out with a light machine gun. And so the modernized Kalashnikov light machine guns RPK-74M (5.45 mm) was addopted in armament. It replaced four modification of light machine guns.
Nowadays Kalashnikov submachine guns, the series 100, are developed with the purpose of expansion of their nomenclature for various types of cartridges and export.
AK101 - the 5,56 mm Kalashnikov submachine gun for cartridge 5,56x45 NATO
AK102 - the same but with a short barrel
AK103 - the 7,62 mm Kalashnikov submachine gun for cartridge 7,62x39
AK104 - the same but with a short barrel
AK105 - 5,45 mm Kalashnikov submachine gun with a short barrel for cartridge 5,45x39.
In 1993 within the framework of conversion of a defensive industry of "IZHMASH" Open Joint Stock Company developed the self-loading hunting carbine "Saiga" on the basis of the Kalashnikov submachine guns.

The AK-47 (shortened from Russian: Автомат Калашникова образца 1947 года, Avtomat Kalashnikova 1947) 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. Compared with the auto-loading rifles used in World War II (the StG-44 aside), the AK-47 was generally more compact, with a shorter range, a smaller 7.62 × 39 mm cartridge, and was capable of selective fire. It was one of the first true assault rifles and remains the most widely used and known. More AK-47 rifles and variants have been produced than any other assault rifle; production continues to this day.

The AK-47, or AK as it is officially known (Russian: Автомат Калашникова, translit. Avtomat Kalashnikova, lit. 'Kalashnikov's Automatic Rifle'), also known as the Kalashnikov, is a gas-operated, 7.62×39mm assault rifle, developed in the Soviet Union by Mikhail Kalashnikov. It is the originating firearm of the Kalashnikov rifle (or "AK") family.
Design work on the AK-47 began in 1945. In 1946, the AK-47 was presented for official military trials, and in 1948, the fixed-stock version was introduced into active service with selected units of the Soviet Army. An early development of the design was the AKS (S—Skladnoy or "folding"), which was equipped with an underfolding metal shoulder stock. In early 1949, the AK-47 was officially accepted by the Soviet Armed Forces[8] and used by the majority of the member states of the Warsaw Pact.
Even after almost seven decades, the model and its variants remain the most popular and widely used assault rifles in the world because of their substantial reliability under harsh conditions, low production costs compared to contemporary Western weapons, availability in virtually every geographic region and ease of use. The AK-47 has been manufactured in many countries and has seen service with armed forces as well as irregular forces and insurgencies worldwide, and was the basis for developing many other types of individual, crew-served and specialised firearms. As of 2004, "Of the estimated 500 million firearms worldwide, approximately 100 million belong to the Kalashnikov family, three-quarters of which are AK-47s".

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.[26]
The original AK was also known as the AK-47. It was a gas-operated, selective-fire weapon. Like all 7.62-mm Kalashnikov assault rifles, it fired the Soviet 7.62 x 39-mm M1943 round and used a standard 30-round curved box magazine. The AK came in two versions: one with a fixed wooden stock, and another, the AKS, with a folding metal stock issued primarily to parachutist and armor troops. Except for the differences in the stock and the lack of a tool kit with the AKS, the two version were identical. The early AKs had no bayonet, but the version with the fixed wooden stock later mounted a detachable knife bayonet.
The improved model, known as the AKM, is easier to produce and operate. It weighs about one kilogram less than the AK. The reduced weight results from using thinner, stamped sheet metal parts rather than machined, forged steel; laminated wood rather than solid wood in the hand guard, forearm, pistol grip, and buttstock; and new lightweight aluminum and plastic magazines. Other improvements include a straighter stock for better control; an improved gas cylinder; a rate-of-fire control alongside the trigger; a rear sight graduated to 1,000 meters rather than 800 meters; and a greatly improved, detachable bayonet.
The AKM also has a folding-stock version, designated AKMS, intended for use by riflemen in armored infantry combat vehicles such as the BMP. Except for its T-shaped, stamped-metal, folding buttstock, the AKMS is identical to the AKM. The folding-stock model can reduce its length from 868 to 699 millimeters.
The safety lever serves two functions when in the upper or "safe" position. First, it blocks dirt from entering the action by covering the slot the bolt carrier lever moves through when the weapon is fired. This also prevents the weapon from being cocked while on "safe".
Second, an extension on the pin holding the lever through the receiver blocks the rear of the trigger, preventing the trigger from being pulled. When the safety lever is moved to "fire, the action may be cycled, and the trigger is the only thing holding the hammer from falling.
When the trigger is pulled, the hammer falls, hits the rear of the firing pin, and the round detonates. Note that the AK-47 bolt is locked closed by rotating when the bolt carrier is moved forward (there is a cam on the top of the bolt that engages a slot in the bolt carrier to accomplish the rotation). The firing pin is free-floating -- there is no spring to hold it retracted until the hammer falls. Consequently, if one manually cycles live rounds through the AK-47, one will observe light indentations on the primers where the firing pit hit against them as the action closed. Consequently, it is inadvisable to chamber live rounds unless you are prepared for the possibility of the weapon firing when you do so.
Slam-fires do not seem to be as common as with the SKS, and it is hard to get enough dirt into the action to cause it to malfunction for that reason. I recall one report of flawless functioning even when the rifle was so covered in mud as to be hardly recognizable as a firearm.
The action is gas-operated: when a round detonates, some gas from the explosion is vented out of a small hole at the top of the barrel near the muzzle. This gas pushes against the front of the piston in the gas tube, which is connected to the bolt carrier. As the bolt carrier is pushed rearward by the gas, the bolt rotates to unlock and moves rearward, and the round in the chamber is extracted and pulled back.
The round is ejected when it hits against a small protrusion on the left side of the receiver as the bolt moves rearward. Simultaneously, the back of the bolt pushes the hammer back and cocks it.
The hammer is held back by the disconnect or (the trigger is almost certainly still pulled, since the action cycles much faster than the operator can release the trigger). The bolt and bolt carrier recoil against the recoil spring and guide rod, and come back forward. As the bolt comes forward, it grabs the top round from the magazine and puts it in the chamber.
There is no feature to hold the bolt open after the last round is fired from the magazine. When the operator releases the trigger, the disconnect or moves rearward and releases the hammer to move about 1/8", at which point it is stopped by the (now released) trigger until the operator pulls the trigger a second time.
In 1990 the Army was equipped with the modernized Kalashnikov submachine gun AK-74M, having folding plastic butt with the accessory placed in it and a plate for mounting optical and night sights.
In 1991 the same modernization was carried out with a light machine gun. And so the modernized Kalashnikov light machine guns RPK-74M (5.45 mm) was addopted in armament. It replaced four modification of light machine guns.
Nowadays Kalashnikov submachine guns, the series 100, are developed with the purpose of expansion of their nomenclature for various types of cartridges and export.
AK101 - the 5,56 mm Kalashnikov submachine gun for cartridge 5,56x45 NATO
AK102 - the same but with a short barrel
AK103 - the 7,62 mm Kalashnikov submachine gun for cartridge 7,62x39
AK104 - the same but with a short barrel
AK105 - 5,45 mm Kalashnikov submachine gun with a short barrel for cartridge 5,45x39.
In 1993 within the framework of conversion of a defensive industry of "IZHMASH" Open Joint Stock Company developed the self-loading hunting carbine "Saiga" on the basis of the Kalashnikov submachine guns.

The AK-47 (shortened from Russian: Автомат Калашникова образца 1947 года, Avtomat Kalashnikova 1947) 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. Compared with the auto-loading rifles used in World War II (the StG-44 aside), the AK-47 was generally more compact, with a shorter range, a smaller 7.62 × 39 mm cartridge, and was capable of selective fire. It was one of the first true assault rifles and remains the most widely used and known. More AK-47 rifles and variants have been produced than any other assault rifle; production continues to this day.
