RWD 23
The RWD 23 was a Polish low-wing trainer aircraft of 1938, constructed by the RWD team, that remained a prototype. Development The aircraft was designed in 1938 to fill the gap in the Polish trainer aircraft, by creating a light low-wing trainer. All trainers built in series in Poland to that point were high-wing monoplanes, for example the RWD-8 or the various biplanes. The main designer was Andrzej Anczutin of the RWD bureau. Among the designers were also Bronisław Żurakowski and Tadeusz Chyliński. Chyliński designed the base mount for its engine.Andrzej Glass (2003). ''Słownik biograficzny techników polskich'', SBTP: Warsaw, p. 24: fragment of its entry about Tadeusz Chyliński: ( pl, W 1937 r. podjął prace w Doświadczalnych Warsztatach Lotniczych ( RWD) jako konstr., jednocześnie kontynuowal studia.

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 Wikimedia project, 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 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".

Monoplane
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 ...

CSS-10
The Dongfeng-41 (DF-41, CSS-20) () is a fourth-generation Chinese solid-fuelled road-mobile intercontinental ballistic missile operated by the People's Liberation Army Rocket Force (formerly the Second Artillery Corps). DF-41 is the fourth and the latest generation of the ''Dongfeng'' series strategic missiles developed by China. The missile was officially unveiled at the China National Day military parade on 1 October 2019. Design The missile reportedly has an operational range between . It is believed to have a top speed of Mach 25, and to be capable of MIRV delivery (up to 10). The development of the MIRV technology is reported to be in response to the deployment of the United States national missile defense system which degrades China's nuclear deterrence capability. The project started in 1986, and may now be coupled with the JL-2 program. Though there have been reports that the DF-41 can carry 6 to 10 warheads, analysts think it most likely carries only three wa ...

Miles Hawk Trainer
The Miles Hawk Trainer was a 1930s British two-seat training monoplane designed by Miles Aircraft Limited. Design and development The Miles Hawk Trainer was developed from the Hawk Major to meet a requirement to supplement the de Havilland Tiger Moth in the training role. The aircraft had dual controls, blind flying equipment and vacuum operated flaps. Based on the attributes of the Trainer, the Air Ministry issued Specification T.40/36, which led directly to the Miles Magister. , Tangmere Military Aviation Museum, September 2009.

Yakovlev UT-2
The Yakovlev UT-2 (russian: Яковлев УТ-2; NATO reporting name "Mink") was a single-engine tandem two-seat low-wing monoplane that was the standard Soviet trainer during the Great Patriotic War. It was used by the Soviet Air Force from 1937 until replaced by the Yakovlev Yak-18 during the 1950s. Development The preceding U-2 (Po-2) biplane was no longer a suitable trainer for the faster modern aircraft entering service, and to fill the role, the UT-2 was designed as a trainer. The new aircraft was designed by Alexander Sergeevich Yakovlev's team at OKB-115. Originally designated AIR-10, it was based upon the AIR-9, but it was simpler, with tandem open cockpits, also omitting slats and flaps. It first flew on 11 July 1935. The AIR-10 won the competition in 1935 and, after minor changes, was accepted as the standard Soviet Air Force trainer. With the disgrace of Alexey Ivanovich Rykov under whom Yakovlev had been working, the initials ''AIR'' were replaced with ''Y ...

ICAR Universal
The ICAR Universal (I.C.A.R. Universal) was a 1930s Romanian two seat monoplane trainer, touring and aerobatics aircraft. Design and development The Universal was designed in 1932, led by engineer Mihail Racoviță, and manufactured in 1934 in the factory of ICAR (aircraft manufacturer), ICAR (''Īntreprinderea de construcţii aeronautice româneşti'') in Bucharest. It was modeled after the German BFW M.23, Messerschmitt M.23b, license — produced by the ICAR. There were three variants of the aircraft. The first was a long-distance single-seater sports aircraft, powered with 150 HP Siemens-Halske Sh 14 radial engine under NACA cowling, giving it a maximum speed of 180 km/h. One such aircraft (YR-MAI) was built for Princess Marina Stirbey. In a place of a forward cockpit, there was an additional fuel tank, giving it an endurance of 6 hours. In the late 1930s, it was converted to two-seater touring aircraft. A further three aircraft were built in a single-seat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackburn Cirrus Minor
The Blackburn Cirrus Minor is a British four-cylinder, inverted, in-line air-cooled aero-engine that was designed and built by the Cirrus Engine Section of Blackburn Aircraft Limited in the late 1930s.

Avia 3
Avia Motors s.r.o. is a Czech automotive manufacturer. It was founded in 1919 as an aircraft maker, and diversified into trucks after 1945. As an aircraft maker it was notable for producing biplane fighter aircraft, especially the B-534. Avia ceased aircraft production in 1963. History The company was founded by Pavel Beneš, Miroslav Hajn, Jaroslav František Koch and Václav Malý in 1919 and became part of Škoda Works a.s. in 1928. During the 1930s the factory became the biggest aircraft producer in Czechoslovakia and moved to Letňany near Prague, where production continues until today. During the Nazi occupation Avia made aircraft for the German Luftwaffe. After the war the company was nationalized and became involved in the automotive industry. It made aircraft until 1963, then concentrated on truck production and continued to make aircraft engines (producing only propellers from 1988). The company was split in 1992 into propeller and truck sections, both using the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tandem
Tandem, or in tandem, is an arrangement in which a team of machines, animals or people are lined up one behind another, all facing in the same direction. The original use of the term in English was in ''tandem harness'', which is used for two or more draft horses, or other draft animals, harnessed in a single line one behind another, as opposed to a pair, harnessed side by side, or a team of several pairs. The tandem harness allows additional animals to provide pulling power for a vehicle designed for a single animal. The English word ''tandem'' derives from the Latin adverb , meaning ''at length'' or ''finally''. It is a word play, using the Latin phrase (referring to time, not position) for English "at length, lengthwise". Tandem bicycles are named for their tandem seating, a more common arrangement than side-by-side " sociable" seating. ''Tandem'' can also be used more generally to refer to any group of persons or objects working together, not necessarily in line. Autom ...
