Mikoyan-Gurevich I-360
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 Mikuli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Republic F-105 Thunderchief
The Republic F-105 Thunderchief is an American supersonic fighter-bomber that served with the United States Air Force from 1958 to 1984. Capable of Mach 2, it conducted the majority of strike bombing missions during the early years of the Vietnam War; it was the only American aircraft to have been removed from combat due to high loss rates. It was originally designed as a single-seat, nuclear- attack aircraft; a two-seat Wild Weasel version was later developed for the specialized Suppression of Enemy Air Defenses (SEAD) role against surface-to-air missile sites. The F-105 was commonly known as the "Thud" by its crews. As a follow-on to the Mach 1 capable North American F-100 Super Sabre, the F-105 was also armed with missiles and a rotary cannon; however, its design was tailored to high-speed low-altitude penetration carrying a single nuclear weapon internally. First flown in 1955, the Thunderchief entered service in 1958. The single-engine F-105 could deliver a bomb load gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angle-of-attack
In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air. In aerodynamics, angle of attack specifies the angle between the chord line of the wing of a fixed-wing aircraft and the vector representing the relative motion between the aircraft and the atmosphere. Since a wing can have twist, a chord line of the whole wing may not be definable, so an alternate reference line is simply defined. Often, the chord line of the root of the wing is chosen as the reference line. Another choice is to use a horizontal line on the fuselage as the reference line (and also as the longitudinal axis).

Letno-Issledovatel'skiy Institut
The Gromov Flight Research Institute or GFRI for short (russian: link=no, Лётно-исследовательский институт имени М. М. Громова, russian: link=no, ЛИИ) is an important Russian State Research Centre which operates an aircraft test base located in Zhukovsky, 40 km south-east of Moscow. The airfield is also known as Ramenskoye air base. The airfield was used as the backup landing site for the Shuttle Buran test program and also as a test base for a Buran's aerodynamic prototype BTS-002. GFRI periodically hosts the MAKS International Air Show (Aviasalon). At present, GFRI also hosts Zhukovsky International Airport. History Foundation The Flight Research Institute was founded on March 8, 1941, in accordance with the decree of Sovnarkom and the Central Committee of the Communist Party of the Soviet Union. Mikhail Gromov, a test pilot, Hero of the Soviet Union, became its first chief. From the very beginning the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nudelman N-37
The Nudelman N-37 was a 37 mm (1.46 in) aircraft autocannon used by the Soviet Union. It was designed during World War II by V. Ya. Nemenov of A.E. Nudelman's OKB-16 to replace the earlier Nudelman-Suranov NS-37 and entered service in 1946. It was 30% lighter than its predecessor at the cost of a 23% lower muzzle velocity. The N-37 was a sizable weapon firing a massive (735 g/26 oz HEI-T, 760 g/27 oz AP-T) shell. Its muzzle velocity was still considerable, but its rate of fire was only 400 rounds per minute. The weapon's considerable recoil and waste gases were problematic for turbojet fighter aircraft, as was finding space for the gun and a useful amount of ammunition, but a single shell was often sufficient to destroy a bomber. The N-37 was used in the MiG-9, MiG-15, MiG-17, and early MiG-19 fighters, the Yakovlev Yak-25, and others. Production lasted through the late 1950s, although it remained in service for many years afterwards. Variants ;N-3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-tail
A T-tail is an empennage configuration in which the tailplane is mounted to the top of the fin. The arrangement looks like the capital letter T, hence the name. The T-tail differs from the standard configuration in which the tailplane is mounted to the fuselage at the base of the fin. Advantages T-tails were common in early jet aircraft. Designers were worried that an engine failure would otherwise damage the horizontal tail. The T-tail is very common on aircraft with engines mounted in nacelles on a high-winged aircraft or on aircraft with the engines mounted on the rear of the fuselage, as it keeps the tail clear of the jet exhaust. Rear-mounting the engines keeps the wings clean and improves short-field performance. This was necessary in early jet aircraft with less powerful engines. T-tail aircraft can have better short-field performance, such as on the Avro RJ-85. The disturbed airflow over a lower stabilizer can make control more difficult at lower speeds. Dur ...

Wing Fence
Wing fences, also known as boundary layer fences and potential fences are fixed aerodynamic devices attached to aircraft wings. Often seen on swept-wing aircraft, wing fences are flat plates fixed to the upper surfaces parallel to the wing chord and in line with the free stream airflow, typically wrapping around the leading edge. By obstructing span-wise airflow along the wing, they prevent the entire wing from stalling at once, as opposed to wingtip devices, which increase aerodynamic efficiency by seeking to recover wing vortex energy. As a swept-wing aircraft slows toward the stall speed of the wing, the angle of the leading edge forces some of the airflow sidewise, toward the wing tip. This process is progressive: airflow near the middle of the wing is affected not only by the leading edge angle, but also the spanwise airflow from the wing root. At the wing tip the airflow can end up being almost all spanwise, as opposed to front-to-back over the wing, meaning that the ef ...

Central Aerohydrodynamic Institute
The Central Aerohydrodynamic Institute (also (Zhukovsky) Central Institute of Aerodynamics, russian: Центра́льный аэрогидродинами́ческий институ́т, ЦАГИ, Tsentral'nyy Aerogidrodinamicheskiy Institut, TsAGI) was founded in Moscow by Russian aviation pioneer Nikolai Yegorovich Zhukovsky on December 1, 1918. History From 1925 and up to the 1930s, TsAGI developed and hosted Tupolev's AGOS (''Aviatziya, Gidroaviatziya i Opytnoye Stroitelstvo'', the "Aviation, Hydroaviation, and Experimental Construction"), the first aircraft design bureau in Soviet Union, and at the time the main one. In 1930, two other major aircraft design bureaus in the country were the Ilyushin's TsKB (''Tsentralnoye Konstruksionnoye Byuro'' means "Central Design Bureau") and an independent, short-lived Kalinin's team in Kharkiv. In 1935 TsAGI was partly relocated to the former dacha settlement ''Otdykh'' (literally, "Relaxation") converted to the new urban-type sett ...

Afterburner
An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, takeoff, and combat. The afterburning process injects additional fuel into a combustor in the jet pipe behind (''i.e.'', "after") the turbine, "reheating" the exhaust gas. Afterburning significantly increases thrust as an alternative to using a bigger engine with its attendant weight penalty, but at the cost of increased fuel consumption (decreased fuel efficiency) which limits its use to short periods. This aircraft application of "reheat" contrasts with the meaning and implementation of "reheat" applicable to gas turbines driving electrical generators and which reduces fuel consumption. Jet engines are referred to as operating ''wet'' when afterburning and ''dry'' when not. An engine producing maximum thrust wet is at ''maximum power,'' while an engine ...

Klimov VK-1
The Klimov VK-1 was the first Soviet jet engine to see significant production. It was developed by and first produced by the GAZ 116 works. Derived from the Rolls-Royce Nene, the engine was also built under licence in China as the Wopen WP-5. Design and development Immediately after World War II, the Soviet Union manufactured copies of first generation German Junkers 004 and BMW 003 engines, which were advanced designs with poor durability, limited by Germany's shortage of rare metals in wartime. However, in 1946, before the Cold War had really begun, the new British Labour government under the prime minister, Clement Attlee, keen to improve diplomatic relations with the Soviet Union, authorised Rolls-Royce to export 40 Rolls-Royce Nene centrifugal flow turbojet engines. In 1958 it was discovered during a visit to Beijing by Whitney Straight, then deputy chairman of Rolls-Royce, that this engine had been copied without license to power the MiG-15 'Fagot', first as the RD-45 ...

Tupolev Tu-16
The Tupolev Tu-16 ( NATO reporting name: Badger) is a twin-engined jet strategic heavy bomber used by the Soviet Union. It has been flown for almost 70 years, and the Chinese license-built Xian H-6 remains in service with the People's Liberation Army Air Force. Development In the late 1940s, the Soviet Union was strongly committed to matching the United States in strategic bombing capability. The Soviets' only long-range bomber at the time was Tupolev's Tu-4 'Bull', a reverse-engineered copy of the American B-29 Superfortress. The development of the notably powerful Mikulin AM-3 turbojet led to the possibility of a large, jet-powered bomber. The Tupolev design bureau began work on the Tu-88 ("Aircraft N") prototypes in 1950. The Tu-88 first flew on 27 April 1952. After winning a competition against the Ilyushin Il-46, it was approved for production in December 1952. The first production bombers entered service with Frontal Aviation in 1954, receiving the service designation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mikulin AM-3
The Mikulin AM-3 (also called RD-3M) was a turbojet engine developed in the Soviet Union by Alexander Mikulin.Gunston 1989, p. 104. Design and development The development of the high-performance single-shaft engine began in 1948. The engine was used in different versions for the Tupolev Tu-16 and Tu-104, as well as the Myasishchev M-4. It had a single-stage low-pressure and an eight-stage high-pressure compressor, powered by a two-stage high-pressure turbine.
