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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Invasion Of Yugoslavia
The invasion of Yugoslavia, also known as the April War or Operation 25, or ''Projekt 25'' was a German-led attack on the Kingdom of Yugoslavia by the Axis powers which began on 6 April 1941 during World War II. The order for the invasion was put forward in " Führer Directive No. 25", which Adolf Hitler issued on 27 March 1941, following a Yugoslav coup d'état that overthrew the pro-Axis government. The invasion commenced with an overwhelming air attack on Belgrade and facilities of the Royal Yugoslav Air Force (VVKJ) by the Luftwaffe (German Air Force) and attacks by German land forces from southwestern Bulgaria. These attacks were followed by German thrusts from Romania, Hungary and the Ostmark (modern-day Austria, then part of Germany). Italian forces were limited to air and artillery attacks until 11 April, when the Italian army attacked towards Ljubljana (in modern-day Slovenia) and through Istria and Lika and down the Dalmatian coast. On the same day, Hungarian for ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Parasol-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 ...

Floatplanes
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Trainer Aircraft
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment that ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

1930s Yugoslav Military Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

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 ...
