Zmaj R-1
The Zmaj R-1 () was a twin-engined prototype bomber produced by Zmaj aircraft of the former Yugoslavia, designed in the 1930s. The aircraft remained a prototype due to a number of difficulties in testing. Design and development During 1936 at the Zmaj factory, Dušan Stankov, then technical manager, initiated the design and construction of a reconnaissance-bomber. After tests in the wind tunnel at Warsaw and acceptance by the Yugoslavian Air Force, the project was designated Zmaj R-1. The team of designers joining Eng. Djordje Ducić and a few young engineers who worked on the design completed the prototype before the beginning of a large aerospace workers strike in April 1940, with final assembly at the military part of the airport in Zemun. The first flight was on 24 April 1940, piloted by reserve Lieutenant Đura E. Đaković, a transport pilot with Aeroput. The initial testing justified all expectations in terms of aerodynamic characteristics and performance, unfortunate ... [...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 ...

Mid-wing Aircraft
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 a ...

1940s Yugoslav Bomber Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Ranger V-770
The Ranger V-770 was an American air-cooled inverted V12 engine, V-12 aircraft engine developed by the Ranger/Fairchild Engines, Ranger Aircraft Engine Division of the Fairchild Aircraft, Fairchild Engine & Aircraft Corporation in the early 1930s. Design and development In 1931, the V-770 design was built, derived from the Ranger L-440, Ranger 6-440 series of inverted inline air-cooled engines, and test flown in the Vought XSO2U-1 Scout. In 1938 it was tested in the Curtiss SO3C Seamew but was found to be unreliable with a tendency to overheat in low-speed flight, but would still be the most produced aircraft to have the V-770, with 795 being built. By 1941 a more developed V-770 was installed in the Fairchild XAT-14 Gunner prototype gunnery school aircraft, which went into limited production as the Fairchild AT-21, Fairchild AT-21 Gunner, of which 174 were built, not including one radial engine prototype. Produced from 1941 to 1945, the V-770 featured a two-piece aluminum alloy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ikarus 215
The Ikarus 215 (Икарус 215 in Serbian) twin-engine plane, was a Yugoslav light bomber and a training aircraft of mixed construction, the prototype flew in 1949. It did not go into production. The prototype was used for training and as a liaison. It was designed and built at the Ikarus factory in Zemun-Belgrade. Design and development Ikarus 215 was designed by engineer constructor Dušan Stankov, and was originally designed before the World War II as a Zmaj R-1 multi-purpose fighter - bomber - but the scout redesigned given the available engines and purpose. The prototype first flew in 1949. It was a twin engined low-wing aircraft of mixed construction, with a crew of two to four (depending on the role). The undercarriage retracted into the engine nacelles backward, while the tail wheel was fixed. The prototype was driven by two twelve-cylinder, air-cooled, in-line piston engines Ranger SVG-770 C-B1. Aircraft wing had a wooden structure lined with plywood, was the trapezo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Yugoslav Air Force
The Royal Yugoslav Air Force ( sh-Latn, Jugoslovensko kraljevsko ratno vazduhoplovstvo, JKRV; sh-Cyrl, Југословенско краљевско ратно ваздухопловство, ЈКРВ; ( sl, Jugoslovansko kraljevo vojno letalstvo, JKVL); lit. "Yugoslav royal war aviation"), was the aerial warfare service component of the Royal Yugoslav Army (itself the land warfare branch of the Kingdom of Yugoslavia). It was formed in 1918 and existed until 1941 and the Invasion of Yugoslavia during World War II. Some 18 aircraft and several hundred aircrew escaped the Axis invasion of April 1941 to the Allied base in Egypt, eventually flying with the Royal Air Force in the Northern Africa initially and then with the Balkan Air Force in Italy and Yugoslavia, with some even going on to join the Soviet Air Force, returning to Yugoslavia in 1944. Germany distributed captured Royal Yugoslav Air Force aircraft and spare parts to Romania, Bulgaria, Finland and the newly created Indep ...

Hispano-Suiza 14AB
The Hispano-Suiza 14AB, a.k.a. Hispano-Suiza Type 80, was a 14-cylinder twin-row air-cooled radial engine. In 1929 the Hispano-Suiza company bought a license to produce the Wright Whirlwind engine. The technology from that engine was used to produce a number of different radial engines with greater displacements, power, and number of cylinders. The most significant of this series of engines was the 14AB, which was a very compact design with relatively good performance, and some 2,500 engines were produced. The 14AB suffered from cooling problems, and many aircraft originally designed for the 14AB were redesigned to use the more reliable Gnome-Rhône 14M series of engines or imported Wright and Pratt & Whitney R-1535 engines. Variants ;14AB-00 ;14AB-02 ;14AB-12:800 hp ;14AB-13:800 hp Applications * Potez 630 The Potez 630 and its derivatives were a family of twin-engined, multirole aircraft developed for the French Air Force in the late 1930s.
