Shvetsov ASh-82
The Shvetsov ASh-82 (M-82) is a Soviet 14-cylinder, two-row, air-cooled radial aircraft engine developed from the Shvetsov M-62. The M-62 was the result of development of the M-25, which was a licensed version of the Wright R-1820 Cyclone. Design and development Arkadiy Shvetsov re-engineered the Wright Cyclone design, through the OKB-19 design bureau he headed, for Russian aviation engine manufacturing practices and metric dimensions and fasteners, reducing the stroke, dimensions and weight. This allowed the engine to be used in light aircraft, where an American-design Twin Cyclone, of some 930 kg (2,045 lb) weight in "dry" condition could not be installed. The engine entered production in 1940 and saw service in a number of Soviet aircraft. It powered the Tupolev Tu-2 and Pe-8 bombers and the inline engine-powered LaGG-3 was adapted for the ASh-82 producing the famous Lavochkin La-5 fighter and its development, Lavochkin La-7, additionally the Lavochkin La-9 with i ...

Arkadiy Shvetsov
Arkady Dmitrievich Shvetsov (russian: Аркадий Дмитриевич Швецов) (January 1892, Nizhniye Sergi, today's Sverdlovsk Oblast - 19 March 1953, Moscow) was a Soviet aircraft engine designer whose OKB was founded in Perm, USSR, in 1934, to produce the Wright Cyclone-derived Shvetsov M-25 engine. Under Shvetsov, his OKB became the primary provider of radial piston engines for Soviet aircraft industry ( Mikulin's and Klimov's OKB were assigned to creation of in-line engines). After his death in 1953, the OKB was taken over by Pavel Soloviev Dr. Pavel Aleksandrovich Solovyov (russian: Павел Александрович Соловьёв; June 26, 1917 – October 13, 1996) was a Soviet engineer born in Alekino in Kineshemsky District of Ivanovo Oblast. He specialised in the des ....

Aircraft Engine Shvetsov ASh-82T
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

Yakovlev Yak-11
The Yakovlev Yak-11 (russian: Яковлев Як-11; NATO reporting name: "Moose") is a trainer aircraft used by the Soviet Air Force and other Soviet-influenced air forces from 1947 until 1962. Design and development The Yakovlev design bureau began work on an advanced trainer based on the Yak-3 fighter in mid-1944, although the trainer was of low priority owing to the ongoing Second World War.Gunston 1995, p. 469. The first prototype of the new trainer, designated Yak-UTI or Yak-3UTI flew in late 1945. It was based on the radial-powered Yak-3U, but with the new Shvetsov ASh-21 seven-cylinder radial replacing the ASh-82 of the Yak-3U.Gordon Komissarov and Komissarov 2005, p. 249. It used the same all-metal wings as the Yak-3U, with a fuselage of mixed metal and wood construction. The pilot and observer sat in tandem under a long canopy with separate sliding hoods. A single synchronised UBS 12.7 mm machine gun and wing racks for two 100 kg (220 lb) bombs compris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Between Overhaul
Time between overhauls (abbreviated as TBO or TBOH) is the manufacturer's recommended number of running hours or calendar time before an aircraft engine or other component requires overhaul. On rotorcraft, many components have recommended or mandatory TBOs, including main rotor blades, tail rotor blades and gearboxes. For engines, the time between overhauls is generally a function of the complexity of the engine and how it is used. Piston-based engines are much more complex than turbine-powered engines, and generally have TBOs on the order of 1,200 to 2,000 hours of running time. They tend toward the lower number if they are new designs, or include boosting options such as a turbocharger. In comparison, jet engines and turboprop A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel ... ...

Ilyushin Il-14
The Ilyushin Il-14 (NATO reporting name: Crate) was a Soviet twin-engine commercial and military personnel and cargo transport aircraft that first flew in 1950, and entered service in 1954. The Il-14 was also manufactured in East Germany by VEB Flugzeugwerke as the VEB 14 and in Czechoslovakia as the Avia 14. The Ilyushin Il-14 was typically replaced by the Antonov An-24 and Yakovlev Yak-40. Design and development The Il-14 was developed as a replacement for the widespread Douglas DC-3 and its Soviet built version, the Lisunov Li-2. A development of the earlier Ilyushin Il-12, (that first flew in 1945), the Il-14 was intended for use in both military and civil applications. The Il-12 had major problems with poor engine-out behaviour. Also, it had less payload capability than was originally planned (although the Il-12 was intended to carry 32 passengers, in service it only carried 18, which was uneconomical). The development into the Il-14 was a vast improvement over the Il-12 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lavochkin La-11
The Lavochkin La-11 (NATO reporting name Fang) was an early post-World War II Soviet long-range piston-engined fighter aircraft. The design was essentially that of a Lavochkin La-9 with additional fuel tanks and the deletion of one of the four 23 mm Nudelman-Suranov NS-23 cannons. Like the La-9, the La-11 was designed to be a low to medium-altitude general-purpose fighter, although the additional fuel tanks were added with the intent of employing the La-11 in the escort fighter role. In reality, the La-11 would go on to serve almost exclusively as an interceptor, with the majority of its engagements during the Korean War seeing it pitted against bomber and transport aircraft. While an improvement over earlier aircraft, the La-9 and La-11 retained the poor high-altitude performance that was common among many Soviet piston-engined airframes, with the La-11 enjoying only a 20 kph (12 mph) advantage over the Boeing B-29 Superfortress at the latter’s cruising alt ...

Lavochkin La-9
The Lavochkin La-9 (NATO reporting name Fritz) was a Soviet fighter aircraft produced shortly after World War II. It was one of the last piston engined fighters to be produced before the widespread adoption of the jet engine. Development La-9 represents a further development of the Lavochkin La-126 prototype. The first prototype, designated La-130 was finished in 1946. Similarity to the famous Lavochkin La-7 was only superficial – the new fighter had an all-metal construction and a laminar flow wing. Weight savings due to elimination of wood from the airframe allowed for greatly improved fuel capacity and four-cannon armament. Mock combat demonstrated that the La-130 was evenly matched with the La-7 but was inferior to the Yakovlev Yak-3 in horizontal planes. The new fighter, officially designated La-9, entered production in August 1946. A total of 1,559 aircraft were built by the end of production in 1948. Variants Like other aircraft designers at the time, Lavochkin was exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lavochkin La-7
The Lavochkin La-7 (russian: Лавочкин Ла-7) was a piston-engined single-seat Soviet fighter aircraft developed during World War II by the Lavochkin Design Bureau. It was a development and refinement of the Lavochkin La-5, and the last in a family of aircraft that had begun with the LaGG-1 in 1938. Its first flight was in early 1944 and it entered service with the Soviet Air Forces later in the year. A small batch of La-7s was given to the Czechoslovak Air Force the following year, but it was otherwise not exported. Armed with two or three cannon, it had a top speed of . The La-7 was felt by its pilots to be at least the equal of any German piston-engined fighter. It was phased out in 1947 by the Soviet Air Force, but served until 1950 with the Czechoslovak Air Force. Design and development By 1943, the La-5 had become a mainstay of the Soviet Air Forces, yet both its head designer, Semyon Lavochkin, as well as the engineers at the Central Aerohydrodynamics Institu ...

LaGG-3
The Lavochkin-Gorbunov-Gudkov LaGG-3 (Лавочкин-Горбунов-Гудков ЛаГГ-3) was a Soviet fighter aircraft of World War II. It was a refinement of the earlier LaGG-1 and was one of the most modern aircraft available to the Soviet Air Force at the time of Germany's invasion in 1941. Compared to its opponents the LaGG-3 was underpowered and, despite its wooden construction, overweight. It was unpopular with Soviet pilots, but despite this, at one point in the war, on average 12 LaGG-3s were being completed daily and 6,528 had been built in total when production switched to the Yak-3 in 1944. The LaGG-3 was steadily improved, forming the basis for the more successful La-5 and La-7. Design and development The prototype of the LaGG-3 was called the I-301 and was designed by Semyon A. Lavochkin, Vladimir P. Gorbunov and Mikhail I. Gudkov. The prototype was later renamed the LaGG-1 and production aircraft were called the LaGG-3. The prototype was designed and pr ...

Inline Engine (aviation)
In aviation, an inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, although more than six is uncommon. The major reciprocating-engine alternative configuration is the radial engine, where the cylinders are placed in a circular or "star" arrangement. The term "inline" is used somewhat differently for aircraft engines than automotive engines. For automotive engines, the term ‘inline’ refers only to straight engines (those with a single bank of cylinders). But for aircraft, ‘inline’ can also refer to engines which are not of the straight configuration, such as V, H, or horizontally opposed. Inline engine configurations ;Straight: Engines with a single bank of cylinders which can be arranged at any angle but typically upright or inverted, (e.g. upright ADC Cirrus, inverted de Havilland Gipsy Major). ; V:Engines with two banks of cylinders with less than 180° betwe ...

Pe-8
The Petlyakov Pe-8 (russian: Петляков Пе-8) was a Soviet Union, Soviet heavy bomber designed before World War II, and the only four-engine bomber the USSR built during the war. Produced in limited numbers, it was used to Bombing of Berlin in World War II, bomb Berlin in August 1941. It was also used for so-called "morale raids" designed to raise the spirit of the Soviet people by exposing Axis powers, Axis vulnerabilities. Its primary mission, however, was to attack German airfields, rail yards and other rear-area facilities at night, although one was used to fly the People's Commissar of Foreign Affairs (Foreign Minister) Vyacheslav Molotov from Moscow to the United States in 1942. Originally designated the TB-7, the aircraft was renamed the Pe-8 after its primary designer, Vladimir Petlyakov, died in a plane crash in 1942. Supply problems complicated the aircraft's production and the Pe-8s also had engine problems. As Soviet morale boosters, they were also high-value t ...
