MiG-27
The Mikoyan MiG-27 (; NATO reporting name: Flogger-D/J) is a variable-sweep ground-attack aircraft, originally built by the Mikoyan-Gurevich design bureau in the Soviet Union and later licence-produced in India by Hindustan Aeronautics as the ''Bahadur'' ("Valiant"). It is based on the Mikoyan-Gurevich MiG-23 fighter aircraft, but optimised for air-to-ground attack. Unlike the MiG-23, the MiG-27 did not have widespread use outside Russia, as most countries opted for the Mikoyan-Gurevich MiG-23BN and Sukhoi Su-22 instead. As of late 2023, all Russian, Indian, Sri Lankan, Ukrainian, and Kazakh MiG-27s have been retired, bringing the type's service to an end. Design and development The MiG-27 shares the basic airframe of the MiG-23, but with a revised nose – nicknamed "''Utkonos''" ("Platypus") or "'' Krokodil Gena''" in Russian service, first introduced on the MiG-23B. Dissatisfaction with the MiG-23BN led to the further development of the basic airframe to accommodate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mikoyan-Gurevich MiG-23
The Mikoyan-Gurevich MiG-23 (; NATO reporting name: Flogger) is a variable-sweep wing, variable-geometry fighter aircraft, designed by the Mikoyan, Mikoyan-Gurevich OKB, design bureau in the Soviet Union. It is a third-generation jet fighter, alongside similar Soviet aircraft such as the Sukhoi Su-17, Su-17 "Fitter". It was the first Soviet fighter to field a look-down/shoot-down radar, the RP-23 Sapfir, and one of the first to be armed with beyond-visual-range missiles. Production started in 1969 and reached large numbers with over 5,000 aircraft built, making it the most produced variable-sweep wing aircraft in history. The MiG-23 remains in limited service with some export customers. The basic design was also used as the basis for the Mikoyan MiG-27, a dedicated ground-attack variant. Among many minor changes, the MiG-27 replaced the MiG-23's nose-mounted radar system with an optical panel holding a laser designator and a TV camera. Development The MiG-23's predecessor, th ...

Kazakh Air Force
The Kazakh Air Defense Forces (, , ) is the aviation warfare branch of the Armed Forces of the Republic of Kazakhstan. Their responsibilities include protecting Kazakh airspace, as well as combat missions in support of other branches of the armed forces. The official holiday of the air forces is Aviation Day on August 18. The Talgat Bigeldinov Military Institute of the Air Defence Forces serves as the only educational service of the air force, having trained cadets from foreign countries including Hungary, Kyrgyzstan and Afghanistan. History Soviet era In the first formation of the Central Asian Military District, it operated a Soviet Air Force district branch led by Major General M.P. Kharitonov. It operated in the early to mid-40s during the Second World War, and consisted of air brigades based on the territory of the Kazakh SSR. The Central Asian Military District was reinstated in 1969 in relation with the increased hostility between the USSR and the People's Republic of C ...

Soviet Air Forces
The Soviet Air Forces (, VVS SSSR; literally "Military Air Forces of the Union of Soviet Socialist Republics"; initialism VVS, sometimes referred to as the "Red Air Force") were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II. The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92. Former Soviet Air Forces' assets were subsequently divided into several air forces of former Republics of the Soviet Union, Soviet republics, including the new Russian Air Force. The "Air March, March of the Pilots" was its marching song. Origins The first military aviation branch of Russia or any of the Soviet Union's constituent states was the short-lived Imperial Russian Air Service, founded in 1912 and disbanded in 1917 with the onset of the Bolshevik Revolution and ...

Variable-sweep Wing
A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft's shape to be changed, it is a feature of a variable-geometry aircraft. A straight wing is most efficient for low-speed flight, but for an aircraft designed for transonic or supersonic flight it is essential that the wing be swept. Most aircraft that travel at those speeds usually have wings (either swept wing or delta wing) with a fixed sweep angle. These are simple and efficient wing designs for high speed flight, but there are performance tradeoffs. One is that the stalling speed is increased, necessitating long runways (unless complex high-lift wing devices are built in). Another is that the aircraft's fuel consumption during subsonic cruise is higher than that of an unswept wing. These tradeoffs are particularly acute for naval carrier-bas ...

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. Design and development After Joseph Stalin's death, the Sukhoi OKB was reopened"Sukhoi Su-7." ''Sukhoi Company Museum.'' Retrieved: 28 January 2011 and by the summer, it began work on a swept-wing front-li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gena The Crocodile
Gena the Crocodile () is a fictional character found in Russian media, particularly animation. History Soviet era: Literature and puppetry Gena is known as a friendly crocodile in the series of animation films '' Gena the Crocodile'', ''Cheburashka'' and '' Shapoklyak'' by Roman Kachanov (Soyuzmultfilm studio). He debuted in the 1966 novel ''Gena the Crocodile and His Friends'' ( ru) by Eduard Uspensky. The crocodile's name is a typical diminutive of the Russian male name Gennady. Gena and Cheburashka, also a title character in the series, are best friends. The 50-year-old Gena works in a zoo as an attraction (or, as the original novel's author Uspensky had put it, "Gena the Crocodile worked in a zoo as a crocodile"). In his spare time, he plays the garmon and likes to sing. His two best-known songs are "Pust' begut neuklyuzhe..." and "Goluboy vagon" ("The Blue Train Car"). One rainy day, which happens to be his birthday, Gena sings the song: "Let the pedestrians run clumsily o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Nav/attack System
A nav/attack system (short for navigation/attack system) is an integrated suite of sensors and navigation equipment that allows a military aircraft to locate and attack specific ground targets or conduct aerial reconnaissance with a high degree of precision. Since the late 1950s, nav/attack systems helped pilots increase the accuracy of releasing ordnance. A computer program would record the aircraft's velocity and use it to pinpoint their location in relationship with the target's location. Early integrated nav/attack systems suffered from poor reliability. Improvements in digital computing technology, advent of the microchip, have resulted in substantially more sophisticated and effective equipment. A typical modern nav/attack system is based around an inertial navigation system (INS) that allows the aircrew to locate the target area without relying on active sensors such as radar Radar is a system that uses radio waves to determine the distance ('' ranging''), directio ...

Intake Ramp
An intake ramp is a rectangular, plate-like device within the air intake of a jet engine, designed to generate a number of shock waves to aid the inlet compression process at supersonic speeds. The ramp sits at an acute angle to deflect the intake air from the longitudinal direction.Gunston and Gilchrist 1993, pp. 188-189. At supersonic flight speeds, the deflection of the air stream creates a number of oblique shock waves at each change of gradient along at the ramp. Air crossing each shock wave suddenly slows to a lower Mach number, thus increasing pressure. Ideally, the first oblique shock wave should intercept the air intake lip, thus avoiding air spillage and pre-entry drag on the outer boundary of the deflected streamtube. For a fixed geometry intake at zero incidence, this condition can only be achieved at one particular flight Mach number, because the angle of the shock wave (to the longitudinal direction) becomes more acute with increasing aircraft speed.
