Tupolev Tu-110
The Tupolev Tu-110 (NATO reporting name: Cooker) was a jet airliner designed and built in the USSR, which saw its maiden flight in 1957. Design and development Realising that the export potential for the Tupolev Tu-104 was limited, the Council of Ministers issued directive No. 1511–846 on 12 August 1956, requiring the Tupolev Design Bureau to develop a four-engined version of the Tu-104, to enable the aircraft to safely cross large expanses of ocean, and improve safety on takeoff in case of engine failure. The Tu-110 was a major redesign of the Tu-104, powered by four Lyulka AL-7 turbojets rated at 5,500 kgf (53.9 kN; 12,100 lbf) thrust each, with two staggered engines in the root of each extended centresection. The first prototype was flown on 11 March 1957. Production of the Tu-110 was authorised at the Kazan Aircraft Factory, with an initial order for ten aircraft, but only three aircraft were completed before the programme was terminated. The production aircraft feat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

1950s Soviet Airliners
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Tupolev Aircraft
Tupolev (russian: Ту́полев, ), officially Joint Stock Company Tupolev, is a Russian aerospace and defence company headquartered in Basmanny District, Moscow. Tupolev is successor to the Soviet Tupolev Design Bureau (OKB-156, design office prefix ''Tu'') founded in 1922 by aerospace pioneer and engineer Andrei Tupolev, who led the company for 50 years until his death in 1972. Tupolev has designed over 100 models of civilian and military aircraft and produced more than 18,000 aircraft for Russia, the Soviet Union and the Eastern Bloc since its founding, and celebrated its 90th anniversary on 22 October 2012. Tupolev is involved in numerous aerospace and defence sectors including development, manufacturing, and overhaul for both civil and military aerospace products such as aircraft and weapons systems, and also missile and naval aviation technologies. In 2006, Tupolev became a division of the United Aircraft Corporation in a merger with Mikoyan, Ilyushin, Irkut, Sukhoi, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tupolev Tu-124
The Tupolev Tu-124 (NATO reporting name: Cookpot) was a 56-passenger short-range twinjet airliner built in the Soviet Union. It was the first Soviet airliner powered by turbofan engines. Design and development Developed from the medium-range Tupolev Tu-104, the Tu-124 was meant to meet Aeroflot's requirement for a regional airliner to replace the Ilyushin Il-14 on domestic routes. Resembling a 75% scaled-down Tu-104, the two were hard to tell apart at a distance but it was not a complete copy of the Tu-104. The Tu-124 had a number of refinements, including double-slotted flaps, a large centre-section airbrake and automatic spoilers. Unlike the Tu-104, the wing trailing edge inboard of the undercarriage was unswept. The Tu-124 had a drogue parachute to be used in an emergency landing or landing on a slippery surface and had low pressure tires for operation from unpaved airfields.Gunston 1995, p. 433.Stroud 1968, pp. 227–229.

A flagship communist state, it was nominally a federal union of fifteen nation ... military transport aircraft developed from the Tupolev Tu-104. It featured a rear ramp loading door and was intended to carry light vehicles, artillery pieces, or up to 70 paratroopers. The fuselage was unpressurized, which meant that passengers would have to use oxygen masks. A single prototype was built and flown, but the aircraft was not put in production.

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] |
