Kuznetsov NK-12
The Kuznetsov NK-12 is a Soviet turboprop engine of the 1950s, designed by the Kuznetsov design bureau. The NK-12 drives two large four-bladed contra-rotating propellers, diameter (NK-12MA), and diameter (NK-12MV). It is the most powerful turboprop engine to enter service. Design and development The design that eventually became the NK-12 turboprop was developed after World War II by a team of Soviet scientists and deported German engineers under Ferdinand Brandner, who had worked for Junkers previously; the design bureau was headed by chief engineer Nikolai D. Kuznetsov. Thus, the NK-12 design evolved from late-war German turboprop studies. This started with the postwar development of the wartime Jumo 022 turboprop design that was designed to develop , weighing . The effort continued with a , weighing , completed by 1947. Evolution to the TV-12 engine required extensive use of new Soviet-developed alloys and was completed in 1951. The NK-12 is the most powerful turboprop ...

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 is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine ex ...

Tupolev Tu-142
The Tupolev Tu-142 (russian: Туполев Ту-142; NATO reporting name: Bear F/J) is a Soviet/Russian maritime reconnaissance and anti-submarine warfare (ASW) aircraft derived from the Tu-95 turboprop strategic bomber. A specialised communications variant designated ''Tu-142MR'' was tasked with long-range communications duties with Soviet ballistic missile submarines. The Tu-142 was designed by the Tupolev design bureau, and manufactured by the Kuibyshev Aviation and Taganrog Machinery Plants from 1968 to 1994. Formerly operated by the Soviet Navy and Ukrainian Air Force, the Tu-142 currently serves with the Russian Navy. Developed in response to the American Polaris programme, the Tu-142 grew out of the need for a viable Soviet ASW platform. It succeeded the failed Tu-95PLO project, Tupolev's first attempt at modifying the Tu-95 for maritime use. The Tu-142 differed from the Tu-95 in having a stretched fuselage to accommodate specialised equipment for its ASW and survei ...

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".

Tupolev Tu-126
The Tupolev Tu-126 (NATO reporting name: Moss) was an airborne early warning and control aircraft developed from the Tupolev Tu-114 airliner by the Tupolev design bureau. It was in service with the armed forces of the Soviet Union from 1965 to 1984. Design and development In 1958 increasing concern over the threat of an American nuclear strike against the USSR from the north led to a new requirement for an airborne radar system, which would avoid the problems and expense of attempting to create a land-based radar system to cover all of the enormous Soviet northern coast. The Tupolev Design Bureau was ordered to design an AEW&C aircraft. After trying to fit the projected radar instrumentation in a Tu-95 and a Tu-116, a decision was made to use the Tupolev Tu-114 with its wider fuselage instead. This solved problems with cooling and operator space that existed with the narrower Tu-95 and Tu-116 designs. To adhere to the flight range requirements, the plane was fitted with an air ...

Tupolev Tu-116
The Tupolev Tu-116 (russian: Tyполев Тy-116) is a turboprop-powered long-range airliner designed by the Tupolev design bureau and built in the USSR. Development The Tu-116, like the Tu-114, was based on the Tu-95 strategic bomber. Both airliners were developed in parallel with the Tu-116 taking priority due to the numerous visits of General Secretary Nikita Khrushchev to both Western and Eastern countries during the so-called Khrushchev Thaw. The aircraft's mission was to transport the head of state together with his security detail and entourage. Concurrent development of the Tu-114 and Tu-116 was justified by Khrushchev's visit to the United States, at which time the Tu-114 might not have been ready. Initially, the airliner was to be developed very quickly, in a little over a year, due to the relative simplicity of modifications. However, the initial introduction date was moved from September 1956 to 1957 because the Tupolev Design Bureau was overloaded with military ...

Operability
Operability is the ability to keep a piece of equipment, a system or a whole industrial installation in a safe and reliable functioning condition, according to pre-defined operational requirements. In a computing systems environment with multiple systems this includes the ability of products, systems and business processes to work together to accomplish a common task such as finding and returning availability of inventory for flight. For a gas turbine engine, operability addresses the installed aerodynamic operation of the engine"Aircraft Propulsion Systems Technology and Design, Gordon C.

Ground Effect Vehicle
A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIG), ground-effect craft, wingship, flarecraft or ekranoplan (russian: экранопла́н – "screenglider"), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water. Typically, it is designed to glide over a level surface (usually over the sea) by making use of ground effect, the aerodynamic interaction between the moving wing and the surface below. Some models can operate over any flat area such as frozen lakes or flat plains similar to a hovercraft. Design A ground-effect vehicle needs some forward velocity to produce lift dynamically, and the principal benefit of operating a wing in ground effect is to reduce its lift-dependent drag. The basic design principle is that the closer the wing operates to an external surface such as the ground, when it is said to be in ground effect, the less drag it feels. An airfoi ...

A-90 Orlyonok
The A-90 ''Orlyonok'' (Russian: Орлёнок, English: "Eaglet") is a Soviet ''ekranoplan'' that was designed by Rostislav Evgenievich Alexeyev of the Central Hydrofoil Design Bureau. The A-90 uses ground effect to fly a few meters above the surface. The Russians classify it as Ekranoplan Class B – it can achieve an altitude of , placing it between Class A – which is limited to ground effect, and Class C, which exploits the ground effect only during take-offs and landings and otherwise functions as a typical airplane. History The Soviet Navy command of the 1960s was very interested in a fast military transport capable of carrying a large payload. The Central Hydrofoil Design Bureau was one of the organizations working on this top-secret project, about which little was known until the fall of the Soviet Union. Chief Designer R. E. Alexeyev designed several prototypes in the 1960s. At the start of the 1970s, Alexeyev designed a medium-sized ekranoplan to be used as ...
