Kuznetsov NK-86
The Kuznetsov NK-86 is a low bypass turbofan engine used on the Ilyushin Il-86 rated at 13,000 kgf or 28,600 lbf (127 KN) thrust. It is made by the Soviet Kuznetsov Design Bureau. It is an upgraded version of the Kuznetsov NK-8. Design and development In 1974, the Minister of Aviation Industry P.V.Dementev ordered ND Kuznetsov to start the development of the engine for the first Soviet wide-body passenger aircraft – Ilyushin Il-86. Kuznetsov was by then intensely engaged with the improvement of OKB military engines destined for Tu-22M and did not have the resources available to fulfill the requirements and the strict deadline set for the IL-86 program. Kuznetsov decided not to create a clean sheet turbofan design because of time and resource constraints but rather to try to improve and upgrade the Kuznetsov NK-8 turbofan engine by improving several of its characteristics. However, from the outset the chief designer made it clear to the Minister and warned that the fuel econ ...

Ilyushin Il-86
The Ilyushin Il-86 (russian: Илью́шин Ил-86; NATO reporting name: Camber) is a short- to medium-range wide-body jet airliner that served as the USSR's first wide-bodied aircraft. Designed and tested by the Ilyushin design bureau in the 1970s, it was certified by the Soviet aircraft industry, manufactured and marketed by the USSR. Developed during the rule of Leonid Brezhnev, the Il-86 was marked by the economic and technological stagnation of the era: it used engines more typical of the late 1960s, spent a decade in development, and failed to enter service in time for the Moscow Olympics, as was originally intended. The type was used by Aeroflot and successor post-Soviet airlines and only three of the total 106 constructed were exported. At the beginning of 2012, only four Il-86s remained in service, all with the Russian Air Force. By the end of 2020 the number in active service was reduced to three. Development Background In the mid-1960s, the United States and W ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Kuznetsov Design Bureau
The Kuznetsov Design Bureau (russian: СНТК им. Н. Д. Кузнецова, also known as OKB-276) was a Russian design bureau for aircraft engines, administrated in Soviet times by Nikolai Dmitriyevich Kuznetsov. It was also known as (G)NPO Trud (or NPO Kuznetsov) and Kuybyshev Engine Design Bureau (KKBM). NPO Trud was replaced in 1994 by a Joint Stock Company (JSC), Kuznetsov R & E C. By the early 2000s the lack of funding caused by the poor economic situation in Russia had brought Kuznetsov on the verge of bankruptcy. In 2009 the Russian government decided to consolidate a number of engine-making companies in the Samara region under a new legal entity. This was named JSC Kuznetsov, after the design bureau. Products The Kuznetzov Bureau first became notable for producing the monstrous Kuznetsov NK-12 turboprop engine that powered the Tupolev Tu-95 bomber beginning in 1952 as a development of the Junkers 0022 engine. The new engine eventually generated about 15,000 horse ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tu-22M
The Tupolev Tu-22M (russian: Туполев Ту-22М; NATO reporting name: Backfire) is a supersonic, variable-sweep wing, long-range strategic and maritime strike bomber developed by the Tupolev Design Bureau in the 1960s. According to some sources, the bomber was believed to be designated Tu-26 at one time. During the Cold War, the Tu-22M was operated by the Soviet Air Forces (VVS) in a missile carrier strategic bombing role, and by the Soviet Naval Aviation (''Aviatsiya Voyenno-Morskogo Flota'', AVMF) in a long-range maritime anti-shipping role. As of 2021, before the 2022 Russian invasion of Ukraine, there were 66 of the aircraft in service. Development In 1962, after the introduction of the Tupolev Tu-22, it became increasingly clear that the aircraft was inadequate in its role as a bomber. In addition to widespread unserviceability and maintenance problems, the Tu-22's handling characteristics proved to be dangerous. Its landing speed was greater than previous bombe ...

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 ...

Lun-class Ekranoplan
The ''Lun''-class ekranoplan (also called Project 903) is the only ground effect vehicle (GEV) to ever be operationally deployed as a warship. designed by Rostislav Alexeyev in 1975 and used by the Soviet and Russian navies from 1987 until sometime in the late 1990s. It flew using lift generated by the ground effect acting on its large wings when within about above the surface of the water. Although they might look similar to traditional aircraft, ekranoplans like the ''Lun'' are not classified as aircraft, seaplanes, hovercraft, or hydrofoils. Rather, crafts like the ''Lun''-class ekranoplan are classified as maritime ships by the International Maritime Organization due to their use of the ground effect, in which the craft glides just above the surface of the water. The ground effect occurs when flying at an altitude of only a few meters above the ocean or ground; drag is greatly reduced by the proximity of the ground preventing the formation of wingtip vortices, thus inc ...
