Ilyushin Il-18 (1946)
The Ilyushin Il-18 was a Soviet four-engined airliner designed and built by Ilyushin immediately after World War II. Although the aircraft itself was successful, its Shvetsov ASh-73TK engines were too unreliable for civilian use and were further needed to equip the Tupolev Tu-4 bomber, so it was cancelled in 1948. Development The Il-18 was developed to meet Aeroflot's need for a high-altitude, long-range aircraft to fly its long-haul national and international routes. It was conceived as a cantilever low-wing monoplane, powered by four Charomskii ACh-32 diesel engines, as initially used in the Ilyushin Il-12, with a tricycle landing gear. To improve the wing's lift-to-drag ratio and the aircraft's maximum speed, the wing was given a very high aspect ratio of 12. It was intended to operate from both paved and unpaved runways with a length of less than . Its main wheels were larger than normal to handle the rough surfaces. The pressurized fuselage was circular in cross-section, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Controllable Pitch Propeller
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. A controllable pitch propeller (CPP) can be efficient for the full range of rotational speeds and load conditions, since its pitch will be varied to absorb the maximum power that the engine is capable of producing. When fully loaded, a vessel will need more propulsion power than when empty. By varying the propeller blades to the optimal pitch, higher efficiency can be obtained, thus saving fuel. A vessel with a VPP can accelerate faster from a standstill and can decelerate much more effectively, making stopping quicker and safer. A CPP can also improve vessel maneuverability by directing a stronger flow of water onto the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilyushin Aircraft
The public joint stock company Ilyushin Aviation Complex, operating as Ilyushin (russian: Илью́шин) or as Ilyushin Design Bureau, is a former Soviet and now a Russian aircraft manufacturer and design bureau, founded in 1933 by Sergey Vladimirovich Ilyushin. Soviet/Russian nomenclature identifies aircraft from Ilyushin with the prefix "Il-" ( ru , Ил-). Ilyushin has its head office in Aeroport District, Northern Administrative Okrug, Moscow. History Ilyushin was established under the Soviet Union. Its operations began on 13 January 1933, by order of P. I. Baranov, People's Commissar of the Heavy Industry and the Head of the Main Department of Aviation Industry. In 1970, the position of chief designer was taken by G. V. Novozhilov In 2006 the Russian government merged Ilyushin with Mikoyan, Irkut, Sukhoi, Tupolev, and Yakovlev under a new company named United Aircraft Corporation.

Tupolev Tu-70
The Tupolev Tu-70 (russian: Туполев Ту-70; NATO reporting name: Cart) was a Soviet passenger variant of the Tu-4 bomber (which was reverse-engineered from the American Boeing B-29 Superfortress) and designed immediately after the end of World War II. It used a number of components from Boeing B-29s that had made emergency landings in the Soviet Union after bombing Japan. It had the first pressurized fuselage in the Soviet Union and first flew on 27 November 1946.Gordon, p. 105 The aircraft was successfully tested, recommended for serial production, but ultimately not produced because of more pressing military orders and because Aeroflot had no requirement for such an aircraft. A military cargo aircraft version was the Tupolev Tu-75. Design and development After basic design work was completed on the Tu-4 bomber, Tupolev decided to design a passenger variant with a pressurized fuselage, given the internal designation of Tu-70. It was intended to use as many Tu-4 component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilyushin Il-32
The Ilyushin Il-32 was a Soviet heavy military glider developed after World War II to deliver of cargo. To facilitate loading and unloading, the glider's nose and tail sections were hinged to swing sideways. The Il-32 required a four-engined aircraft to tow it safely; it was canceled when it became clear that no such tug was going to be available after the Tupolev Tu-75 and Ilyushin Il-18 programs were both canceled because of shortages of their intended Shvetsov ASh-73 engines. Development After the end of World War II, the Soviets devoted a considerable amount of effort to developing heavy transport gliders to deliver troops during an airborne assault. As part of this effort, the Council of Ministers ordered the Ilyushin design bureau on 20 September 1947 to begin work on a glider capable of carrying of cargo, including 60 troops or a cannon with its prime mover, ammunition and crew. Its intended tug was the Tupolev Tu-75, a four-engined transport derived from the Tupolev Tu-4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tushino
Tushino ( rus, Тушино, p=ˈtuʂɨnə) is a former village and town to the north of Moscow, which has been part of the city's area since 1960. Between 1939 and 1960, Tushino was classed as a separate town. The Skhodnya River flows across the southern part of Tushino. History The village was attested since the late 14th century as an estate of boyar Vasili Ivanovich Kvashnin-Tusha and later his sons Pyotr and Semyon. In the middle of the 16th century, the village and the nearby Saviour Monastery were acquired by the Troitse-Sergiyeva Lavra. One of the finest of Russian tent-like churches was built in the monastery under Ivan the Terrible. In the late 16th century, the monastery used to provide lodging for foreign diplomatic missions before their arrival in Moscow. During the Time of Troubles, False Dmitry II and his supporters settled in Tushino between 1608 and 1610. The Tushino camp was a replica of the Muscovite court, having its own prikazes and the Patriarch. From ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C-47 Skytrain
The Douglas C-47 Skytrain or Dakota (RAF, RAAF, RCAF, RNZAF, and SAAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II and remained in front-line service with various military operators for many years.Parker 2013, pp. 13, 35, 37, 39, 45-47. Design and development The C-47 differed from the civilian DC-3 by way of numerous modifications, including being fitted with a cargo door, hoist attachment and strengthened floor - along with a shortened tail cone for glider-towing shackles, and an astrodome in the cabin roof.Wilson, Stewart. ''Aircraft of WWII''. Fyshwick, ACT, Australia: Aerospace Publications Pty Ltd., 1998. . During World War II, the armed forces of many countries used the C-47 and modified DC-3s for the transport of troops, cargo, and wounded. The U.S. naval designation was R4D. More than 10,000 aircraft were produced in Long Beach and Santa Monica, California, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lisunov Li-2
The Lisunov Li-2 (NATO reporting name: Cab), originally designated PS-84, was a license-built Soviet-version of the Douglas DC-3. It was produced by Factory #84 in Moscow-Khimki and, after evacuation in 1941, at TAPO in Tashkent. The project was directed by aeronautical engineer Boris Pavlovich Lisunov. Design and development The Soviet Union received its first DC-2 in 1935. A total of 18 DC-3s had been ordered on 11 April 1936, and the government of the USSR purchased 21 DC-3s for operation by Aeroflot before World War II. A production license was awarded to the government of the USSR on 15 July 1936. Lisunov spent two years at the Douglas Aircraft Company, between November 1936 and April 1939 translating the design. One of the engineers who accompanied him to Douglas was Vladimir Mikhailovich Myasishchev. Design work and production were undertaken at State Aviation Factory 84 in Khimki (now a suburb of Moscow).

Sergey Ilyushin
Sergey Vladimirovich Ilyushin (russian: Серге́й Владимирович Илью́шин; – 9 February 1977) was a Soviet aircraft designer who founded the Ilyushin aircraft design bureau. He designed the Il-2 Shturmovik, which made its maiden flight in 1939. It is the most produced warplane, and remains the second most-produced aircraft in history, with some 36,000+ built, behind the US Cessna 172. Biography Early years Born in the village of Dilyalevo in Russian family, as the youngest of 11 children in a peasant family, the largely self-taught Ilyushin left home at an early age. He worked as a factory laborer, ditch-digger at construction sites, and cleaner of gutters at a dye plant in Petrograd. In 1910, he learned that jobs were available at Kolomyazhsky Racetrack as a groundskeeper. The racetrack was also the site of the first All-Russia Festival of Ballooning in autumn of 1910, and Ilyushin assisted in unpacking crates and setting up equipment. He was also ...

Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a pilot controls the aircraft. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11, 2001 attacks, all major airlines fortified their cockpits against access by hijackers. Etymology The word cockpit seems to have been used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore. The word "cockswain" in turn derives from the old English terms for "boat-servant" (''coque'' is the French word for "shell"; and ''swain'' was old English for boy or se ...

Deicing
Deicing is the process of removing snow, ice or frost from a surface. Anti-icing is the application of chemicals that not only deice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier. Deicing can be accomplished by mechanical methods (scraping, pushing); through the application of heat; by use of dry or liquid chemicals designed to lower the freezing point of water (various salts or brines, alcohols, glycols); or by a combination of these different techniques. Application areas Roadways In 2013, an estimated 14 million tons of salt were used for deicing roads in North America. Deicing of roads has traditionally been done with salt, spread by snowplows or dump trucks designed to spread it, often mixed with sand and gravel, on slick roads. Sodium chloride (rock salt) is normally used, as it is inexpensive and readily available in large quantities. However, sinc ...
