Nudelman-Rikhter NR-30
The Nudelman-Rikhter NR-30 was a Soviet autocannon widely used in military aircraft of the Soviet Union and Warsaw Pact. It was designed by A.E. Nudelman and A. A. Rikhter, entering service in 1954. Description Prior to the introduction of the NR-30, most Soviet autocannon were of 23 or 37 mm calibre and often used in combination. For instance, the Mikoyan-Gurevich MiG-15 was equipped with two NR-23's and a single N-37. The two were mismatched; the NR-23 was a rapid-fire weapon with relatively low explosive power, while the N-37 was extremely powerful, typically able to destroy a bomber with a single hit, but with very a low firing rate which made it unsuited to firing at manoeuvring targets like fighters. Moreover, the two had very different ballistics which meant that long-range fire would result in one or the other set of guns being properly aimed. The NR-30 was an attempt to solve this problem by introducing a single weapon that could serve in both roles. It was es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a Federation, federal union of Republics of the Soviet Union, fifteen national republics; in practice, both Government of the Soviet Union, its government and Economy of the Soviet Union, its economy were highly Soviet-type economic planning, centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian Soviet Federative Socialist Republic, Russian SFSR. Other major cities included Saint Petersburg, Leningrad (Russian SFSR), Kyiv, Kiev (Ukrainian Soviet Socialist Republic, Ukrainian SSR), Minsk (Byelorussian Soviet Socialist Republic, Byelorussian SSR), Tas ...

Armor-piercing Shot And Shell
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate either body armour or vehicle armour. From the 1860s to 1950s, a major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly-armoured interiors. From the 1920s onwards, armour-piercing weapons were required for anti-tank warfare. AP rounds smaller than 20 mm are intended for lightly-armoured targets such as body armour, bulletproof glass, and lightly-armoured vehicles. As tank armour improved during World War II, anti-vehicle rounds began to use a smaller but dense penetrating body within a larger shell, firing at very high muzzle velocity. Modern penetrators are long rods of dense material like tungsten or depleted uranium (DU) that further improve the terminal ballistics. History The late 1850s saw the development of the ironclad warship, which carried wrought iron armour of considerable thickness. This armour w ...

30 Mm Artillery
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Su-22
The Sukhoi Su-17 (''izdeliye'' S-32) is a variable-sweep wing fighter-bomber developed for the Soviet military. Its NATO reporting name is "Fitter". Developed from the Sukhoi Su-7, the Su-17 was the first variable-sweep wing aircraft to enter Soviet service. Two subsequent Sukhoi aircraft, the Su-20 and Su-22, have usually been regarded as variants of the Su-17. The Su-17/20/22 series has had a long career and has been operated by many other air forces of including the Russian Federation, other former Soviet republics, the former Warsaw Pact, countries in the Arab world, Angola and Peru. Development Shortly after the Su-7 fighter-bomber was put into service, the Sukhoi Design Bureau was ordered to develop a deep modernization program for the aircraft in the early 1960s. The program would be aimed primarily at updating on-board avionics and the takeoff/landing performance characteristics. The concept of variable-geometry wings - something gaining wider attention at that time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Republic Of China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, o ...

Shenyang J-6
The Shenyang J-6 ( Chinese: 歼-6; designated F-6 for export versions; NATO reporting name: Farmer) is the Chinese-built version of the Soviet MiG-19 'Farmer' fighter aircraft, the world's first mass-produced supersonic aircraft. Design and development Although the MiG-19 had a comparatively short life in Soviet service, the Chinese came to value its agility, turning performance, and powerful cannon armament, and produced it for their own use between 1958 and 1981. While the basic Soviet-built MiG-19 has been retired from all nations, the Shenyang J-6 still flies for nine of its original 15 operators, however, in a very limited capacity. The J-6 airframe contributed to the Chinese ground attack version, the Q-5, which still flies for numerous nations. The J-6 was considered "disposable" and was intended to be operated for only 100 flight hours (or approximately 100 sorties) before being overhauled. The Pakistan Air Force was often able to extend this to 130 hours with dil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sukhoi Su-7
The Sukhoi Su-7 ( NATO designation name: Fitter-A) is a swept wing, supersonic fighter aircraft developed by the Soviet Union in 1955. Originally, it was designed as a tactical, low-level dogfighter, but was not successful in this role. On the other hand, the soon-introduced Su-7B series became the main Soviet fighter-bomber and ground-attack aircraft of the 1960s. The Su-7 was rugged in its simplicity, but its Lyulka AL-7 engine had such high fuel consumption that it seriously limited the aircraft's payload, as even short-range missions required that at least two hardpoints be used to carry drop tanks rather than ordnance.

Mikoyan-Gurevich MiG-21
The Mikoyan-Gurevich MiG-21 (russian: Микоян и Гуревич МиГ-21; NATO reporting name: Fishbed) is a supersonic jet fighter and interceptor aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. Its nicknames include: "balalaika", because its planform resembles the stringed musical instrument of the same name; "''Ołówek''", Polish for "pencil", due to the shape of its fuselage, and "''Én Bạc''", meaning "silver swallow", in Vietnamese. Approximately 60 countries across four continents have flown the MiG-21, and it still serves many nations six decades after its maiden flight. It set aviation records, becoming the most-produced supersonic jet aircraft in aviation history, the most-produced combat aircraft since the Korean War and, previously, the longest production run of any combat aircraft (now exceeded by both the McDonnell Douglas F-15 Eagle and General Dynamics F-16 Fighting Falcon).

Mikoyan-Gurevich MiG-19
The Mikoyan-Gurevich MiG-19 (russian: Микоян и Гуревич МиГ-19; NATO reporting name: Farmer) is a Soviet second generation, single-seat, twinjet fighter aircraft, the world's first mass-produced supersonic aircraft. It was the first Soviet production aircraft capable of supersonic speeds in level flight. A comparable U.S. " Century Series" fighter was the North American F-100 Super Sabre, although the MiG-19 primarily fought against the more modern McDonnell Douglas F-4 Phantom II and Republic F-105 Thunderchief over North Vietnam. This aircraft was originally used by the Soviet Union but it was later used by the People's Liberation Army Air Force. Design and development In 1950 the Mikoyan-Gurevich (MiG) design bureau (also known as OKB-155) began work on a new fighter aircraft, intended to have a greater range than the existing MiG-15 and MiG-17 aircraft, and capable of reaching supersonic speeds in level flight. MiG chose to use two of the new Mikulin AM- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cropped NR-30
Cropping is the removal of unwanted outer areas from a photographic or illustrated image. The process usually consists of the removal of some of the peripheral areas of an image to remove extraneous trash from the picture, to improve its framing, to change the aspect ratio, or to accentuate or isolate the subject matter from its background. Depending on the application, this can be performed on a physical photograph, artwork, or film footage, or it can be achieved digitally by using image editing software. The process of cropping is common to the photographic, film processing, broadcasting, graphic design, and printing businesses. In photography, print, and design In the printing, graphic design and photography industries, cropping is the removal of unwanted areas from the periphery of a photographic or illustrated image. Cropping is one of the most basic photo manipulation processes, and it is carried out to remove an unwanted object or irrelevant noise from the periph ...
