SibNIA TVS-2DTS
The SibNIA TVS-2MS, TVS-2DT, TR-301 and TVS-2DTS () are a series of single-engined, biplane utility aircraft developed by the Siberian Aeronautics Research Institute () as a light multi-role successor to the Antonov An-2, An-2. The TVS-2 eventually was reconsidered as an entirely new airplane, and the position of the An-2's new replacement was re-opened. The abbreviation TVS stands for Turbovintowoy, or "Turboprop Airplane" (самолёт). Development The TVS-2DTS is a comprehensively modernized derivative of the twelve-seat An-2 biplane. The aircraft made its first flight on July 10, 2018, in Novosibirsk. It was planned to build five test aircraft to achieve certification in 2020.AERO''AN-2 Doppeldecker: Neuauflage einer Legende'' access date 9 January 2021. In September 2019, it was announced that the SibNIA TVS-2DTS would not become the replacement of the An-2 aircraft type, rather the Ministry of Industry and Trade (Russia), Russian Ministry of Industry and Trade asked t ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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 outsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winglet
Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft's drag. Such devices reduce drag by increasing the height of the lifting system, without greatly increasing the wingspan. Extending the span would reduce lift-induced drag, but would increase parasitic drag and would require boosting the strength and weight of the wing. At some point, there is no net benefit from further increased span. There may also be operational considerations that limit the allowable wingspan (e.g. available width at airport gates). Physics When a conventional wing generates lift, it also experiences lift-induced drag. Higher pressure air under the wing flows to the lower pressure surface on top at the wingtip, which results in a vortex caused by the forward motion of the aircraft. Trefftz-plane theory shows that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stavropol Air Company
Stavropol (, ), known as Voroshilovsk from 1935 until 1943, is a city and the administrative centre of Stavropol Krai, in southern Russia. As of the 2021 Census, its population was 547,820, making it one of Russia's fastest growing cities. Etymology The name ''Stavropol'' () is a Russian rendering of the Greek name, ( 'City of the Cross'). According to legend, soldiers found a stone cross there while building the fortress in the city's future location. It is not related to Byzantine Stauroupolis (ancient Aphrodisias) in Asia Minor, nor to the city of Stavropol-on-Volga (now called Tolyatti). History It was founded on October 22, 1777Charter of Stavropol, Article 2 following the Russo-Turkish War of 1768–1774 as a military encampment, and was granted city status in 1785. Prince Grigory Potemkin, who founded Stavropol as one of ten fortresses built between Azov and Mozdok at the request of Catherine the Great, played a leading role in the creation of the city. ...

SibNIA
Chaplygin Siberian Scientific Research Institute Of Aviation (SibNIA) () is a research institute based in Novosibirsk, Russia, and established in 1941. SIBNIA is one of Russia's leading aviation research institutes, with departments devoted to aerodynamics, avionics testing, full-scale fatigue testing, thermal strength testing, fatigue and loading spectra, and dynamic strength testing. Researchers at SIBNIA have published work on topics such as localization of the sources of acoustic emissions in strength testing of aviation materials, fatigue and fracture in steel and concrete structures, piezotransducer amplification, strengths of materials, and metallurgy. Since 1943, over 180 aircraft and 200 aircraft components have been tested at SIBNIA's facilities. SIBNIA came into existence in 1941 when the Central Aerohydrodynamics Institute (TsAGI) was evacuated to Novosibirsk to escape from the German advance on Moscow.

Russian Air Force
The Russian Air Force () is a branch of the Russian Aerospace Forces, the latter being formed on 1 August 2015 with the merging of the Russian Air Force and the Russian Aerospace Defence Forces. After the dissolution of the Soviet Union, the reborn Russian armed forces began to be created on 7 May 1992 following Boris Yeltsin's creation of the Ministry of Defence (Russia), Ministry of Defence. However, the Russian Federation's air force can trace its lineage and traditions back to the Imperial Russian Air Service (1912–1917) and the Soviet Air Forces (1918–1991). History The Russian Air Force, officially established on 12 August 1912, as part of the Imperial Russian Air Service, has a long and complex history. It began as one of the earliest military aviation units globally, although its early years saw slow development due to the constraints of World War I. After the Russian Revolution, Russian Revolution of 1917, the air service was reorganised under the Soviet regime, ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naryan-Mar Air Enterprise
Naryan-Mar (; ) is a sea and river port town and the administrative center of the Nenets Autonomous Okrug, Russia. The town is situated on the right bank of the Pechora River, upstream from the river's mouth, on the Barents Sea. Naryan-Mar lies north of the Arctic Circle. Population: 17,000 (1973). About half of the population of Nenetsia lives in the city. History Industrial development in the area around Naryan-Mar began in 1930, in the course of the first five-year plan of the Soviet Union. The growth of the region was the direct result of the development of the Pechora coalfield and the construction of related industrial infrastructure. Naryan-Mar was for many years a center of the lumber industry, and possesses several large, and currently defunct, lumber mills. At present, the biggest employer in the town is the petroleum company LUKoil. The town's importance derives from being the only developed commercial port in an area of several thousand square miles.

Aviation Of Kolyma
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the ''Wright Flyer'', the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet engine which enabled aviation ...
