Avia B.534
The Avia B-534 is a Czechoslovak biplane developed and manufactured by aviation company Avia. It was produced during the period between the First World War and the Second World War. The B-534 was perhaps one of the most well-known Czechoslovakian aircraft of the era. During 1932, work had commenced on the development of a new single-engined biplane fighter aircraft, the Avia B-34, which had been designed by aeronautical engineer František Novotný. During its development, various alternative engines were considered and trialled before eventually settling upon the license-built Hispano-Suiza 12Y engine. Other improvements during the prototype stage included the adoption of an enclosed cockpit along with a revised tail and undercarriage arrangement. On 14 April 1934, the second prototype, while flown by test pilot Václav Kočí, successfully attained a Czechoslovak national speed record of . Deliveries of production aircraft to the Czechoslovak Air Force commenced in Octob ... [...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 ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Polikarpov
Polikarpov Design Bureau was a Soviet OKB (design bureau) for aircraft, led by Nikolai Nikolaevich Polikarpov. Dux Factory was acquired by the USSR and became part of Polikarpov. After the death of Polikarpov on 30 July 1944 at the age of 52, his OKB was absorbed into Lavochkin, but with some of its engineers going to Mikoyan-Gurevich and its production facilities going to Sukhoi. For a long time the Polikarpov OKB headquarters were located at Aircraft plant #1 (formerly Dux Factory) in Moscow, where its purpose-built building still stands. Designs Polikarpov designs: Bombers * TB-2 twin-engined biplane bomber prototype, 1930 * SPB (D) twin-engined dive bomber developed from the VIT-2, 1940 * NB (T) medium bomber prototype, 1944 Fighters * I-1 (IL-400) monoplane fighter prototype, 1923 * DI-1 (2I-N1) twin-seat biplane fighter prototype, 1926 * I-3 biplane fighter, 1928 * DI-2 two-seat biplane fighter developed from the I-3, 1929 * I-6 biplane fighter prototype, 1930 ...

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 ...

Gloster Gladiator
The Gloster Gladiator is a British biplane fighter. It was used by the Royal Air Force (RAF) and the Fleet Air Arm (FAA) (as the Sea Gladiator variant) and was exported to a number of other air forces during the late 1930s. Developed privately as the Gloster SS.37, it was the RAF's last biplane fighter aircraft, and was rendered obsolete by newer monoplane designs even as it was being introduced. Though often pitted against more formidable foes during the early days of the Second World War, it acquitted itself reasonably well in combat. The Gladiator saw action in almost all theatres during the Second World War, with a large number of air forces, some of them on the Axis side. The RAF used it in France, Norway, Greece, the defence of Malta, the Middle East, and the brief Anglo-Iraqi War (during which the Royal Iraqi Air Force was similarly equipped). Other countries deploying the Gladiator included China against Japan, beginning in 1938; Finland (along with Swedish voluntee ...

Hawker Fury
The Hawker Fury is a British biplane fighter aircraft used by the Royal Air Force in the 1930s. It was a fast, agile aircraft, and the first interceptor in RAF service capable of speed higher than 200 mph (321 kmh). It was the fighter counterpart to the Hawker Hart light bomber. Design and development The Hawker Fury was a development of the earlier Hawker F.20/27 prototype fighter, replacing the radial engine of the F.20/27 with the new Rolls-Royce F.XI V-12 engine (later known as the Rolls-Royce Kestrel), which was also used by Hawker's new light bomber, the Hawker Hart. The new fighter prototype, known as the Hawker Hornet, first flew at Brooklands, Surrey, in March 1929.Mason 1992, p.213. The Hornet was a single-engined biplane, with single bay wings, initially powered by a 420 hp (313 kW) Rolls-Royce F.XIC engine enclosed by a smooth, streamlined cowling but was quickly re-engined with a 480 hp (358 kW) Kestrel IS.Goulding 1986, p.37.

Praga E-44
The Praga BH-44 (designated E-44 by the Czechoslovak Air Force) was a prototype Czechoslovak fighter biplane of the early 1930s. Only two were built, the rival Avia B-34 being ordered instead. Design and development In 1932, ČKD-Praga, the aircraft department of the Czechoslovak company Praga, entered a competition to design a new fighter for the Czechoslovak Air Force, with its design, the BH-44, competing against designs from Avia (the B-34Green and Swanborough 1994, p. 36.) and Letov (the Š-231Green and Swanborough 1994, pp. 334–335.). The BH-44 was a single-bay biplane of mixed construction, with wooden wings and a fabric covered, steel-tube fuselage. Powerplant was a single Praga ESV water-cooled V12 engine. The first prototype made its maiden flight on 19 July 1932. Performance was unimpressive, as the engine delivered only instead of the promised .

Army
An army (from Old French ''armee'', itself derived from the Latin verb ''armāre'', meaning "to arm", and related to the Latin noun ''arma'', meaning "arms" or "weapons"), ground force or land force is a fighting force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or country. It may also include aviation assets by possessing an army aviation component. Within a national military force, the word army may also mean a field army. In some countries, such as France and China, the term "army", especially in its plural form "armies", has the broader meaning of armed forces as a whole, while retaining the colloquial sense of land forces. To differentiate the colloquial army from the formal concept of military force, the term is qualified, for example in France the land force is called ''Armée de terre'', meaning Land Army, and the air and space force is called ''Armée de l'Air et de l’Esp ...
