Емкость магазина всего 3 или 5 патронов. Но для винтовки такого калибра это норма. Помимо стандартных патронов 20х мм винтовка может быть адаптирована под советский патрон 14,5х мм. Перезарядка после выстрела осуществляется вручную. Современная оптика и мощный патрон позволяют уничтожать цели на дальностях, которые просто недоступны обычным винтовкам. Максимальная эффективная дальность стрельбы составляет впечатляющие 4 метра.

Для этого оружия разработаны специальные патроны, которые позволяют выполнять широкий круг задач. Например, ломающийся бронебойный снаряд FAP, который демонстрирует отличные показатели летальности одновременно для небронированных и бронированных целей.

Или 20x мм патрон PELE с вольфрамовым сердечником для пробивания с повышенным заброневым действием. Боеприпас отлично подходит для поражения личного состава перевозимого в легкой бронетехнике. Самые большие крупнокалиберные винтовки разработаны под патрон 20х мм.

Но востребовано ли такое оружие сейчас? Как показывает практика — да. Высокоточные крупнокалиберные винтовки широко используются в спецоперациях различными странами. Например, капрал канадской армии Роб Фурлонг, вооруженный крупнокалиберной винтовкой, во время операции Анаконда в Афганистане с расстояния 2 м уничтожил пулеметный расчет.

The original Gatling gun had fallen out of favor because of the need for an external power source to rotate the barrel assembly, but the new generation of turbojet-powered fighters offered sufficient electrical power to operate the gun, and electric operation offered superior reliability to a gas operated weapon. With multiple barrels, the rate of fire per barrel could be lower than a single-barrel revolver cannon while still giving a superior total rate of fire.

The Army issued GE the contract in for "Project Vulcan," a six-barrel weapon capable of firing 6, rounds per minute. Although European designers were moving towards heavier 30 mm weapons for better hitting power, the U. The first GE prototypes of the T were ground-fired in The development of the F revealed that the Vulcan later re-designated M61 suffered problems with its linked ammunition, being prone to mis-feed and presenting a foreign-object damage FOD hazard with discarded links.

A link-less feed system was developed for the upgraded M61A1, which subsequently became the standard cannon armament of U. It is likely to remain in service for at least another decade. General Electric sold design and production for the M61 along with their other rotary cannon to General Dynamics. Description The Vulcan is a Gatling gun: The multiple barrels provide both a very high rate of fire--around rounds per second--and contribute to long weapon life by minimizing barrel erosion and heat generation.

Mean time between jams or failures is in excess of 10, rounds, making it an extremely reliable weapon. The success of the Vulcan Project and its subsequent progeny, the very-high-speed Gatling gun, has led to guns of the same configuration being referred to as Vulcan Cannon , which can sometimes confuse nomenclature on the subject.

Most aircraft versions of the M61 are hydraulically driven and electrically primed. The gun rotor, barrel assembly and ammunition feed system are rotated by a hydraulic drive motor through a system of flexible drive shafts. The round is fired by an electric priming system where an electrical current from a firing lead passes through the firing pin to the primer as each round is rotated into the firing position.

The self-powered version, the GAU-4 called M in Army service , is gas-operated, tapping gun gas from three of the six barrels to operate the mechanism. The self-powered Vulcan weighs about 10 lb 4. Click on Picture to enlarge M61 ammo belt The initial M61 used linked, belted ammunition, but the ejection of spent links created considerable and ultimately insuperable problems. The original weapon was soon replaced by the M61A1, with a linkless feed system.

Depending on the application, the feed system can be either single-ended ejecting spent cases and unfired rounds or double-ended returning casings back to the magazine. A disadvantage of the M61 is that the bulk of the weapon, its feed system, and ammunition drum makes it difficult to fit it into a densely packed airframe. The feed system must be custom-designed for each application, adding lb kg to the complete weapon. Most aircraft installations are double-ended, because the ejection of empty cartridges can cause a foreign-object damage FOD hazard for jet engines and because the retention of spent cases assists in maintaining the center of gravity of the aircraft.

The first aircraft to carry the M61A1 was the D model of the F, starting in A lighter version of the Vulcan developed for use on the F Raptor, the M61A2, is mechanically the same as the M61A1, but with thinner barrels to reduce overall mass to lb The rotor and housing have also been modified to remove any piece of metal not absolutely needed for operation and replaces some metal components with lighter weight materials.

Until the late s the M61 primarily used the M50 series of ammunition in various types, typically firing a gram 3. The PGU has not been without problems, however. A USAF safety report noted 24 premature detonation mishaps causing serious damage in many cases in 12 years, compared to only two such mishaps in the entire recorded history of the M56 round.

Disadvantages Despite its reliability and tremendous rate of fire, the Vulcan has been increasingly criticized in recent years for its limited performance. The ballistic characteristics of the 20 mm round are relatively poor, with the projectile losing energy quickly, and its destructive power and accuracy are lacking compared to the heavier mm rounds favored by European and Russian air forces.

Efforts to develop a larger-caliber replacement for the M61 have thus far had limited success. The USAF spent a great deal of money in s on the 25 mm GAU-7 cannon for the F Eagle, using caseless ammunition, but it proved to be a failure and was abandoned in favor of the Vulcan. The five-barrel GAU Equalizer 25 mm gun used in the AV-8B Harrier II is a Vulcan derivative, but despite greater hitting power since it fires a heavier round at virtually the same muzzle velocity it had yet to find wide application except for the F Lightning-II which was reduced to four barrel.

Another criticism is that despite its high rate of fire, the Gatling-type weapon is hampered by the time it takes for the weapon to spin up to its maximum rotation speed about 0. To overcome this shortfall, the M61A2, with its lower inertia can be powered by a hydraulic motor with 5, P. Applications The Vulcan was first used in the F Starfighter.

It was designed into Air Force versions of the A-7D where it replaced the Naval standard dual cannon, and subsequently adopted by the Navy on future fighters.

Most significantly, it was designed into an air superiority version of the F-4E Phantom II which lacked a cannon in all previous versions since it was believed that beyond-visual-range AIM-7 Sparrow missiles made guns obsolete. Combat experience in Vietnam showed that a gun could be more effective than guided missiles in many combat situations, and that a gun pod was less satisfactory than an internal gun.

Both pods ejected empty casings and unfired rounds rather than retaining them. Both pods contained 1, rounds of ammunition, with a loaded weight of 1, lb kg and 1, lb kg respectively.

Unfortunately, during service in the Vietnam War the pods proved to be relatively inaccurate: A variant with much shorter barrels, designated the M was also developed for use on the M35 Armament Subsystem for use on the AH-1G Cobra helicopter.

This variant fed from ammunition boxes fitted to the landing skid and was developed to provide the AH-1 helicopter with a longer ranging suppressive fire system before the adoption of the M97 Universal Turret mounting the M cannon.

It fires standard M50 ammunition at 6, rounds per minute rate selectable in certain installations. The lesson of WWII was that the German, Italian and Japanese fighters could reach out and touch the Americans with their cannon main armament, while the latter had to get up close and personal with the.

The 20mm Hispano carried by the P was a relatively low velocity weapon. Results were high rate of fire and a high rate of barrel wear out. With propellants of the time and period metallurgy it was a good idea but one that was not ready until new technology came along.

Gatling in the 19th century. The Vulcan was first fired in pre-production form in , and made its first flight in the Lockheed F Initial problems with the gas bleed resulted in a temporary suspension of firing tests, until a better venting system for the F gun compartment was designed. Today, after a period of neglect when guns were thought to be rendered obsolete by missiles , the M61 in one form or another, is an integral part of the armament of modern fighters such as the F, F and of course the F Construction The multiple-barrels cannon offers both advantages in firing rate and in barrel life.

As the 6 barrels revolve, they proceed through the different stages of the gun firing cycle. Each barrel is fired as it passes through the top position, after which the spent case is extracted and ejected, and a new round is fed and chambered - all at different positions on the circle described by the revolving barrel.

This means that the firing rate is multiplied by the number of barrels, as six barrels are being loaded in parallel. Major drawback is that ammunition is consumed at a vast rate, requiring large ammo magazines. The gun is fed through long linked belts of ammo, and although the gun appeared from early on in the development to be extremely reliable, the unprecedented rate of fire caused severe problems with these belts.

The links connection the rounds often bent, broke or stretched, causing the gun to jam. Furthermore, provisions had to be made to dispose of the links.

As a result, development of a new linkless feed system quickly started. Inside the drum, the rounds tips to the middle are placed in a giant Archimedean screw which moves them into the conveyor belt feeding the gun.

In the F and some other installations M61A1 installations are tailor-made to each aircraft type , the empty case is transported back to the drum via a second conveyor belt. Both conveyor belts are housed in strong flexible ducts, and are powered by the gun, as well as the screw inside the drum which is driven via a high-power flexible coupling.

The stationary breech housing has a deep elliptical slot in its inner wall in which run 6 cam followers, on the breech of each barrel. The followers are driven linearly in and out of the associated breech, successively chambering, firing and extracting the rounds.

The breech rotor, to which are attached the 6 barrels, revolves inside the breech housing. At the muzzle end, the 6 barrels are fitted in a clamp. This clamp can be replaced by other models, thereby offering a means to vary the barrel angles and create slightly different dispersion patterns. The inside of each barrel is provided with a twisted groove to give the rounds a spinning motion. F Installation The M61 installation in the F encountered some initial problems, most notably in September when firing the gun was temporarily forbidden.

Two incidents had occurred in which gun firing resulted in un-commanded yawing movements. The cause of this problem was an accelerometer in the flight-control system being affected by the vibrations caused by the operation of the gun. The accelerometer fed false data into the flight computers, which initiated the yaw movements. Simple insulating the accelerometer from vibration solved the problem. All operational Fs delivered to date were retrofitted during The gun itself is located in the upper port side of the fuselage, with the gun port on the port side of the cockpit.

The ammo drum has a round capacity. The gun controller is the electronics unit which actually controls the firing of the gun. A voltage pulse is sent out from the gun controller to fire each round in a firing burst. At the end of a burst when the trigger is released, the gun clears itself. In the clearing operation, 5 to 9 unfired rounds are cycled through the gun without firing pulses, and are fed back to the ammo drum. These rounds are carried for the duration of the flight as spent rounds and cannot be used.

The SMS Stores Management System has a rounds remaining counting function which counts each firing pulse from the gun controller and subtracts these from the loaded number of rounds. In the clearing operation, however, there are no pulses or any way of determining the actual number of rounds cleared, therefore the SMS assumes 7. Due to this fact there can be a discrepancy between the rounds remaining on the SCP and the actual number of rounds left to be fired.

This discrepancy can become larger with increasing number of clearings. Hot gasses from the muzzle have left carbon traces, which -if not removed- corode the paint. Close up of the M61 gunport on a Norwegian FA. The copper color is copper-grease, applied to the gunport to protect it from the hot gasses during firing. Burns from the gasses are difficult to clean after a firing period.

The gun takes about 0. Some critics notably defense analyst Pierre Sprey in a paper called First Rounds Count argue that the aim is at it truest when the pilot pulls the trigger, and that it starts wandering off almost immediately. A revolver cannon such as the Mauser BK27 fitted in the Tornado does not have this problem, as it reaches its maximum rate of fire instantly. The BK27 fires at 1, rpm, or 28 rounds per second. The rate of fire of 6, rpm or rps means that shells are spaced by 0.

Работы по созданию многоствольного пулемета были начаты в х годах ХХ века. Таковой тип орудия, с высочайшими показателями скорострельности и большой плотностью огня, разрабатывался в качестве вооружения для реактивных тактических истребителей ВВС США. Прототипом для сотворения первого эталона шестиствольного М61 Vulcan послужил германский ти ствольный авиапулемет Fokker-Leimberger, в базе конструкции которого заложена револьверно-батарейная схема Гатлинга.

Пользуясь этой схемой была сотворена отлично равновесная конструкция многоствольного пулемета с блоком крутящихся стволов, при этом все нужные операции производились за один оборот блока.

М61 Vulcan — это шестиствольный авиационный пулемет пушка имеющий воздушное остывание ствола и боевое снаряжение патроном 20 х мм с электрокапсюльным типом воспламенения. Система подачи боеприпасов в шестиствольный пулемет Vulcan без звеньевая, из цилиндрического магазина емкость которого патронов. Пулемет с магазином соединены 2-ух конвейерной подачей, при которой отстреленные гильзы ворачиваются назад в магазин при помощи возвратимого сборочного потока.

Весь массив патронов в магазине движется вдоль его оси, крутится же только выполненный в форме спирали центральный направляющий ротор, меж витками которого размещены боеприпасы. При стрельбе, из магазина синхронизировано извлекаются два патрона, а с обратной стороны в него помещаются две стрелянные гильзы, которые потом размещаются в конвейере.

Стреляющий механизм имеет внешнюю схему привода с мощностью 14,7 кВт. Таковой тип привода не просит установки газового регулятора и не опасается осечек. Снаряжение патронов может быть: Сначала годов компанией General Electric было принято решение сделать особые навесные контейнеры навесные пушечные установки для размещения шестиствольного мм М61 Vulcan.

Конструкция навесных пушечных установок обеих моделей имеет схожие габаритные размеры корпуса длина — 5,05 м, поперечник — 0,56 м и унифицированные мм навесные узлы, дозволяющие устанавливать таковой пулемет в ППУ на самые разные модели боевых самолетов.

Полный боекомплект состоит из снарядов, вес в оснащенном виде составляет — кг, вес без снаряжения — кг. Пулемет в навесном контейнере зафиксирован и закреплен бездвижно. В качестве прицела при стрельбе применяется бортовая система корректировки огня либо зрительный стрелковый прицел. Экстракция стрелянных гильз при ведении огня происходит наружу, за борт установки. Студент из Германии Михельсон используя пользующуюся популярностью игрушечную пушку-бластер Nerf системы Vulcan сконструировал достаточно смешное, но очень полезное автоматическое устройство, отлично подходящее для защиты местности.

При помощи нескольких дополнительных приводов, обычный электроники и компьютерных программ, оружие-сторож Нерф умеет автоматом распознать, отследить цель, а потом и поразить ее. При всем этом обладатель орудия может находится в укрытии. Ударно-спусковой механизм механизированного устройства Нерф Вулкан подключается к ноутбуку и аппаратно-программному средству интегральная схема Arduino Uno с процессорами.

Его срабатывание происходит тогда, когда следящая и сканирующая местность вокруг веб-камера, фиксирует движение ненужного объекта. При всем этом веб-камера устанавливается на фронтальной панели ноутбука, а компьютерная программка настраивается на движение. Магазин Nerf Vulcan имеет емкость в зарядов, в качестве поражающих частей могут быть дротики либо стрелы. В компьютерную программку механизированного часового может быть заложена четкая настройка, умеющая предугадывать следующие движения объектов и делать четкие предупреждающие выстрелы.

Вероятна настройка дополнительной функции орудия на то, чтоб можно было закончить стрельбу в случае попадания в зону видимости вэбки какой-нибудь определенной символики либо отличительных символов.
