Antonov AN-2 Colt
The Antonov An-2 ("kukuruznik"—corn crop duster; USAF/DoD reporting name Type 22, NATO reporting name Colt) is a Soviet mass-produced single-engine biplane utility/agricultural aircraft designed and manufactured by the Antonov Design Bureau beginning in 1947. Its durability, high lifting power, and ability to take off and land from poor runways have given it a long service life. The An-2 was produced up to 2001 and remains in service with military and civilian operators around the world. The An-2 was designed as a utility aircraft for use in forestry and agriculture, but the basic airframe is highly adaptable and numerous variants of the type have been developed; these include hopper-equipped versions for crop-dusting, scientific versions for atmospheric sampling, water-bombers for fighting forest-fires, flying ambulances, float-equipped seaplane versions and lightly armed combat versions for dropping paratroops.Harpole, Tom"Antonovs in America" [...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 ...

Design Bureau
OKB is a transliteration of the Russian initials of "" – , meaning 'experiment and design bureau'. During the Soviet era, OKBs were closed institutions working on design and prototyping of advanced technology, usually for military applications. The english language corresponding term for such bureau's occupation is Research and Development. A bureau was officially identified by a number, and often semi-officially by the name of its lead designer – for example, OKB-51 was led by Pavel Sukhoi, and it eventually became known as the OKB of Sukhoi. Successful and famous bureaus often retained this name even after the death or replacement of their designers. These relatively small, state-run organisations were not intended for the mass production of aircraft, rockets, or other vehicles or equipment which they designed. However, they usually had the facilities and resources to construct prototypes. Designs accepted by the state were then assigned to factories for mass production. A ...

PZL-Mielec
PZL Mielec (''Polskie Zakłady Lotnicze'' - Polish Aviation Works), formerly WSK-Mielec (''Wytwórnia Sprzętu Komunikacyjnego'') and WSK "PZL-Mielec" is a Polish aerospace manufacturer based in Mielec. It is the largest aerospace manufacturer in postwar Poland. In 2007, it was acquired by Sikorsky Aircraft Corporation, which retained the brand name. Between 1948 and 2014, the company manufactured approximately 15,600 aircraft. History Before 1945 Between 1938 and 1939, a factory was built in Mielec, designated PZL WP-2 (''Wytwórnia Płatowców 2''—''Airframe Factory no. 2''), which was a division of PZL in Warsaw (''Państwowe Zakłady Lotnicze''—''State Aviation Works''), the biggest Polish aviation works, but production was only starting there at the outbreak of World War II. In March 1939, manufacturing commenced of the first aircraft — PZL.37 Łoś bombers, assembled from components delivered from the PZL WP-1 factory in Warsaw.Gruszczyński, J. (2014), pp. 8–10 T ...

An-2 OK-HFL EDST 02
An alpha privative or, rarely, privative a (from Latin ', from Ancient Greek ) is the prefix ''a-'' or ''an-'' (before vowels) that is used in Indo-European languages such as Sanskrit and Greek and in words borrowed therefrom to express negation or absence, for example the English words of greek origin ''atypical'', ''anesthetic'', and ''analgesic''. It is derived from a Proto-Indo-European syllabic nasal *', the zero ablaut grade of the negation *', i.e. /n/ used as a vowel. For this reason, it usually appears as ' before vowels (e.g. '' an-alphabetism'', '' an-esthesia'', '' an-archy''). It shares the same root with the Greek prefix ' or ', in Greek or , that is also privative (e.g. '). It is not to be confused with, among other things, an alpha copulative (e.g. ') or the prepositional component ' (i.e. the preposition ' with ecthlipsis or elision of its final vowel before a following vowel; e.g. ').

Polikarpov Po-2
The Polikarpov Po-2 (also U-2, for its initial ''uchebnyy'', 'training', role as a flight instruction aircraft) served as an all-weather multirole Soviet biplane, nicknamed ''Kukuruznik'' (russian: Кукурузник,Gunston 1995, p. 292. NATO reporting name "Mule".)

Wright R-1820
The Wright R-1820 Cyclone 9 is an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25. Design and development The R-1820 Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements, the R-1820 entered production in 1931. The engine remained in production well into the 1950s. The R-1820 was built under license by Lycoming, Pratt & Whitney Canada, and also, during World War II, by the Studebaker Corporation. The Soviet Union had purchased a license for the design, and the Shvetsov ''OKB'' was formed to metricate the American specification powerplant for Soviet government-factory production as the ''M-25'', with the R-1820's general design features used by the Shvetsov design bureau for many of their future rad ...

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 ...

Shvetsov ASh-62
The Shvetsov ASh-62 (Russian: АШ-62, designated M-62 before 1941) is a nine-cylinder, air-cooled, radial aircraft engine produced in the Soviet Union. A version of this engine is produced in Poland as the ASz-62 and the People's Republic of China as the HS-5. Design and development The ASh-62 was a development of the Wright R-1820 Cyclone that had been built in Russia under licence as the Shvetsov M-25, the main improvements including a two-speed supercharger and a more efficient induction system. Power was increased from the Cyclone's 775 hp to 1,000 hp. First run in 1937, licensed versions are still in production by WSK "PZL-Kalisz" in Poland (as of 2017).Gruszczyński, Jerzy. ''W pierwszej lidze dostawców'', "Lotnictwo Aviation International" Nr. 9/2017, p. 34-37 (in Polish) The Ash-62 was also produced in China. It is estimated that 40,361 were produced in the USSR.
