Rogožarski R-313
The Rogozarski R-313 (Рогожарски Р-313 in Serbian) was a two-seat twin-engined monoplane designed as a fighter/light bomber/reconnaissance aircraft in Yugoslavia before World War II. It was designed and built at the Rogozarski factory in Belgrade. Design, construction and development The Rogozarski R-313 was a two-seater twin-engined fighter/light bomber/reconnaissance aircraft. It was powered by two in-line Walter Sagitta IIR engines, both fitted with a compressor; each was capable of 493 hp. The elliptical, wooden fuselage was covered in plywood which was also used to 'skin' the round-tipped, trapezoidal wings. The engine nacelles also housed the landing gear. The tail-wheel was, like the main landing gear, retractable. The fuel tank was located in the centre section between the wings. The reconnaissance variant of this aircraft was due to be equipped with a camera, a radio, a fixed 20mm cannon and a single FN 7.9mm machine gun, flexibly mounted. As a light bomb ...

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 ...

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 ...

Low-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 ...

Reconnaissance Aircraft
A reconnaissance aircraft (colloquially, a spy plane) is a military aircraft designed or adapted to perform aerial reconnaissance with roles including collection of imagery intelligence (including using photography), signals intelligence, as well as measurement and signature intelligence. Modern technology has also enabled some aircraft and UAVs to carry out real-time surveillance in addition to general intelligence gathering. Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual observation and scouting of enemy movement. An example is the PBY Catalina maritime patrol flying boat used by the Allies in World War II: a flight of U.S. Navy Catalinas spotted part of the Japanese fleet approaching Midway Island, beginning the Battle of Midway. History Prior to the 20th century machines for powered and controllable flight were not available to military forces, but some attempts were made to use lighter than air craft ...

Rogožarski Aircraft
Rogožarski () was a Yugoslav aircraft manufacturer. History Officially established on 22 April 1924 under the name of ''Prva Srpska Fabrika Aeroplana Živojin Rogožarski'' ( en, First Serbian Aircraft Factory of Živojin Rogožarski), the factory was responsible along with Ikarus for most of Yugoslavia's air industry between the world wars. Initially, the factory repaired aircraft confiscated in the First World War, and soon started to manufacture local aircraft, and licensed manufacture as well. Nationalised in 1946, the factory was merged along with Zmaj into Ikarus which continued in the aeronautical industry until 1962. The factory Rogožarski has made a total of 286 aircraft.

Rogožarski PVT
The Rogožarski PVT ( sr-Cyrl, Рогожарски ПВТ; transliterated as Rogozarski PWT in German and as Rogojarsky PVT in some older English sources) was a single-engined, two-seat parasol winged aircraft designed as an advanced and fighter trainer in Yugoslavia before World War II. Over 60 were built, serving with the Yugoslav Royal Air Force (YAF) until the fall of Yugoslavia in 1941. After that, some PVTs were used by the newly formed Air Force of the Independent State of Croatia, sometimes as ground attack aircraft. Design and development The ''Prva Srpska Fabrika Aeroplana Živojin Rogožarski'' was the first Serbian aircraft manufacturer in Yugoslavia, founded in 1924. In about 1933 its team of Rudolf Fizir, Sima Milutinović, Kosta Sivčev and Adem Biščević designed the PVT, a training aircraft with tandem open cockpits in an oval wooden monocoque fuselage. Its wooden, canvas covered wings were swept and parasol mounted well above the fuselage with pairs of li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rogožarski SIM-XIV-H
The Rogožarski SIM-XIV-H ( sr, Рогожарски СИМ-XIV-Х) was a 1930s Yugoslav coastal reconnaissance floatplane and light bomber, twin-engined, with three crew members. It was designed and built at the Rogožarski factory in Belgrade. Design and development In January 1937, the Yugoslav Navy Air Service issued a specification for a twin-engined coastal reconnaissance aircraft,Green 1962, p. 201. to replace the Ikarus IO flying boat. To meet this requirement, Rogozarski proposed the SIM-XIV-H, a twin-engined floatplane designed by Sima Milutinović, and this type was selected by the Yugoslav navy, with the first prototype making its maiden flight on 8 February 1938. The SIM-XIV-H was a low winged monoplane of mixed wood and metal construction, with an oval section monocoque fuselage. The wing was braced to the fuselage by steel-tube struts, with the tail also braced. It had a glazed nose, with a gun turret armed with a single machine gun mounted above the nose. The ...

Walter Aircraft Engines
Walter Aircraft Engines is an aircraft engine manufacturer and former automotive manufacturer. Its notable products include the M601 turboprop. The company is based in Prague, Czech Republic. It has been a subsidiary of GE Aviation since July 2008. History Josef Walter founded the company in 1911 to make motorcycles and motor tricycles. It started to make automobiles in 1913: initially its own models, and later the Fiat 508, 514, 522 and 524 under licence. By 1926 Walter was Czechoslovakia's fourth-largest car maker by sales volume. In 1929 it still held fourth place, and production peaked at 1,498 cars for the year. By 1932 Walter production had slumped to 217 cars for the year. The figure recovered to 474 in 1933, but fell again to 102 in 1936 and to only 13 in 1937. Walter ceased car production in 1954. From the early 1920s Walter also manufactured BMW aircraft engines under license, as well as its own family of air-cooled radial piston engines. In the 1930s Walter als ...
