Bücker Bü 181 Bestmann
The Bücker Bü 181 ''Bestmann'' is a two-seater, single-engine aerobatic monoplane aircraft built by Bücker Flugzeugbau in Rangsdorf, near Berlin and extensively used by the Luftwaffe in World War II. Development The Bücker Bü 181 was named ''Bestmann'' after a German maritime term designating a member of the deck crew on coastal or fishing vessels. The prototype Bü 181 (D-ERBV) made its maiden flight in February 1939 with Chief Pilot Arthur Benitz at the controls. After thorough works and official flight testing by the Reichsluftfahrtministerium (RLM) the Bü 181 was nominated to be the standard primary trainer for the Luftwaffe. Series production of the Bü 181 commenced in 1940. The production types were designated B to C with only slight variations between each, and could be powered by the Hirth HM 500 A or B. Design The Bü 181 aircraft was a single-engine low-wing monoplane with fixed undercarriage, split flap, twin controls and two adjustable seats arrange ...

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 ...

Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...

Zlín Z-281
Zlín (in 1949–1989 Gottwaldov; ; german: Zlin) is a city in the Czech Republic. It has about 73,000 inhabitants. It is the seat of the Zlín Region and it lies on the Dřevnice river. It is known as an industrial centre. The development of the modern city is closely connected to the Bata Shoes company and its social scheme, developed after the World War I. A large part of the city is urbanistically and architecturally valuable and is protected by law as an urban monument zone. Administrative parts Zlín is made up of 16 city parts and villages: *Zlín *Prštné (Zlín II) *Louky (Zlín III) *Mladcová (Zlín IV) *Příluky (Zlín V) *Jaroslavice (Zlín VI) *Kudlov (Zlín VII) *Malenovice (Zlín VIII) *Chlum *Klečůvka *Kostelec *Lhotka *Lužkovice *Salaš *Štípa *Velíková Etymology There are several legends about the origin of the name of the city, according to which it was derived from ''slín'' (i.e. "marl") or ''zlaté japko'' (i.e. "golden apple").

Czechoslovak Air Force
The Czechoslovak Air Force (''Československé letectvo'') or the Czechoslovak Army Air Force (''Československé vojenské letectvo'') was the air force branch of the Czechoslovak Army formed in October 1918. The armed forces of Czechoslovakia ceased to exist on 31 December 1992. By the end of the year, all aircraft of the Czechoslovak Air Force were divided between the Czech Air Force and the Slovak Air Force. Organization On 30 October 1918, the establishment of Aviation Corps (''Letecký sbor'') marked the beginning of the Czechoslovak Air Force. Under the First Republic, the air force was an integral service of the Czechoslovak army. During peacetime, the army aviation was a subordinate agency of the Ministry of National Defence within its 3rd Department of Aviation (''III. odbor (letecký) Ministerstva národní obrany'') under the command of divisional general Jaroslav Fajfr (as of October 1938). It was anticipated that individual squadrons and flights would be attach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protectorate Of Bohemia And Moravia
The Protectorate of Bohemia and Moravia; cs, Protektorát Čechy a Morava; its territory was called by the Nazis ("the rest of Czechia"). was a partially annexed territory of Nazi Germany established on 16 March 1939 following the German occupation of the Czech lands. The protectorate's population was mostly ethnic Czech. After the Munich Agreement of September 1938, Germany had annexed the German-majority Sudetenland from Czechoslovakia. Following the establishment of the independent Slovak Republic on 14 March 1939, and the German occupation of the Czech rump state the next day, German leader Adolf Hitler established the protectorate on 16 March 1939 by a proclamation from Prague Castle. The creation of the protectorate violated the Munich Agreement.Crowhurst, Patrick (2020) ''Hitler and Czechoslovakia in World War II: Domination and Retaliation''. Bloomsbury Academic. p. 96, .

Fokker
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912.

Aerobatics
Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term is a portmanteau of "aerial" and "acrobatics". Aerobatics are performed in aeroplanes and gliders for training, recreation, entertainment, and sport. Additionally, some helicopters, such as the MBB Bo 105, are capable of limited aerobatic manoeuvres. An example of a fully aerobatic helicopter, capable of performing loops and rolls, is the Westland Lynx. Most aerobatic manoeuvres involve rotation of the aircraft about its longitudinal (roll) axis or lateral (pitch) axis. Other maneuvers, such as a spin, displace the aircraft about its vertical (yaw) axis. Manoeuvres are often combined to form a complete aerobatic sequence for entertainment or competition. Aerobatic flying requires a broader set of piloting skills and exposes the aircraft to greater structural stress than for normal flight. In some countries, the pilot must wear a ...

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...
