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".

Polikarpov I-180
The Polikarpov I-180 () was a 1938 Soviet Union, Soviet fighter aircraft, fighter prototype. It was the last attempt to extract performance from the basic Polikarpov I-16 design.Green 1973, p. 165. The development cycle was plagued with problems, especially with the death of the star Soviet test pilot Valery Chkalov in one of the prototypes. Design and development The I-180 represented a further development of the basic Polikarpov I-16, I-16 design in order to take advantage of the new radial engines coming into service. It was designed to meet a requirement of the Soviet Air Force of January 1938 for a new interceptor aircraft with a radial engine. It was preceded by a series of projected I-16 variants with a more powerful Tumansky M-88 two-row radial engine: I-161, I-162, I-163, I-164, I-165, I-166 and I-167. The I-180 was a single-engine, low-wing monoplane aircraft of mixed construction with a duraluminum frame covered in plywood and fabric. The pilot sat near the tailfin in ...

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 futu ...

Nikolai Nikolaevich Polikarpov
Nikolai Nikolaevich Polikarpov (; – 30 July 1944) was a Soviet aeronautical engineer and aircraft designer, known as the "King of Fighters". He designed the I-15 series of fighters, and the I-16 Ishak ( phonetically close to its or designation) "Little Donkey" fighter. Biography Polikarpov was born in the village of Georgievskoye near Livny in Oryol Governorate. He was the son of a village priest in the Russian Orthodox Church. He initially also trained for the priesthood and studied at the Oryol Seminary before moving to Saint Petersburg Polytechnical University in 1911, where he became fascinated with the fledgling aviation work being carried out under the shipbuilding department. Polikarpov graduated in 1916 and went to work for Igor Sikorski, the head of production at the Russian Baltic Carriage Factory. While working for Sikorski, Polikarpov helped design the massive Ilya Muromets four-engine bomber for the Imperial Russian Air Force. Soviet career Polikarpov stay ...

Polikarpov I-15
The Polikarpov I-15 () was a Soviet biplane fighter aircraft of the 1930s. Nicknamed ''Chaika'' (', "gull") because of its gulled upper wings,Gunston 1995, p. 299.Green and Swanborough 1979, p. 10. it was operated in large numbers by the Soviet Air Force, and together with the Polikarpov I-16 monoplane, was one of the standard fighters of the Spanish Republicans during the Spanish Civil War, where it was called Chato (snub-nose). Design and development The design for the 14th fighter for the VVS, the I-14, started as an advanced (for the era) monoplane under the direction of Andrei Tupolev. He grew concerned that the design would not mature, and ordered two backup biplane designs as the I-14A and B just to be safe. Polikarpov had just been released from prison in August 1932, and was handed the I-14A project. When both the I-14 and I-14A were ordered into production, Polikarpov's design, a development of the I-5 fighter became the famous I-15. The first flight was made in ...

Flying Squirrel
Flying squirrels (scientifically known as Pteromyini or Petauristini) are a tribe (biology), tribe of 50 species of squirrels in the family (biology), family Squirrel, Sciuridae. Despite their name, they are not in fact capable of full flight in the same way as birds or bats, but they are able to gliding flight, glide from one tree to another with the aid of a patagium, a furred skin membrane that stretches from wrist to ankle. Their long tails also provide stability as they glide. Anatomically they are very similar to other squirrels with a number of adaptations to suit their lifestyle; their limb bones are longer and their hand bones, foot bones, and distal vertebrae are shorter. Flying squirrels are able to steer and exert control over their glide path with their limbs and tail. Molecular studies have shown that flying squirrels are Monophyly, monophyletic (having a common ancestor with no non-flying descendants) and originated some 18–20 million years ago.

Donkey
The donkey or ass is a domesticated equine. It derives from the African wild ass, ''Equus africanus'', and may be classified either as a subspecies thereof, ''Equus africanus asinus'', or as a separate species, ''Equus asinus''. It was domesticated in Africa some years ago, and has been used mainly as a working animal since that time. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as Working animal, draught or pack animal, pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding, as pets, and for livestock protection in developed countries. An adult male donkey is a ''jack'' or ''jackass'', an adult female is a ''jenny'' or ''jennet'', and an immature donkey of either sex is a ''foal''.
