AEKKEA-RAAB R-29
The AEKKEA-RAAB R-29 was a Greek single-seat parasol monoplane trainer and/or light fighter developed by Antonius Raab, a German aircraft designer, with his Greek partners and was the sole Raab aircraft to be developed in Greece. Design and development The airplane had wooden wings and an Elektron (alloy) metal-tube fuselage.Raab, 1984, p.134 However, there is no exact record for produced numbers. The R-29 was a new design developed by Raab's Greek company in late 1936 but shared structural characteristics with the preceding R-27 type (a type also first recorded as an AEKKEA-RAAB product by ''Jane's'' 1935 ed., most probably designed earlier by Raab and never produced), which featured an inline Hispano-Suiza 12Y engine, retractable undercarriage and twin machine-guns. Export documents to Spain and ''Jane's'' (1936 ed.) reported it as a fighter, but Raab later described it as a trainer,Raab, 1984, p.134 which would be borne out by the low powered engine chosen.

AEKKEA-RAAB
The history of AEKKEA (''Anonymos Etaireia Kataskevis Kai Ekmetallefseos Aeroplanon'' - ''Societe Anonyme Pour la Fabrication et l'Exploitation des Avions Raab''), an aircraft maker based in Greece, is connected with the history of a talented German aircraft designer, Antonius Raab (his first name alternatively known as Antonios, in Greek, and Antonio, in Spanish after his involvement in Spain). Establishment In Germany, Raab was the co-founder of Raab-Katzenstein, an aircraft manufacturing company. A devoted anti-Nazi, Raab was forced out of his homeland, and after attempts to establish his company in Estonia and Latvia, ended up in 1935 in Greece, where he had the support of a high-ranking Air Force officer (Gen. P. Gazis). With this support, he and his Greek partners founded a company called ''AEKKEA'' (which stood for "Anonymos Etaireia Kataskevis Kai Ekmetallefseos Aeroplanon", or, in French, the "international" language employed in Greece at the time "Societe Anonyme Pour ...

Monoplane
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 ...

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] |
Raab-Katzenstein
Raab-Katzenstein was a 1920s German aircraft manufacturer based in Kassel. History The main character of the company was its designer Gerhard Fieseler. Following World War I, he returned to printing, but yearned to return to flying. In 1926, he closed his print shop in Eschweiler and became a flight instructor with Raab-Katzenstein and continued to hone his flying skills, becoming an accomplished stunt pilot. In 1927, he performed a particularly daring routine in Zürich and started to command increasingly high fees for appearances. In 1928 while working at Raab-Katzenstein, he designed his own stunt plane, the Fieseler F1 (also known as the Raab-Katzenstein RK-26 Tigerschwalbe), which was offered and sold to a Swedish company called AB Svenska Järnvägverkstaderna (ASJA), which built 25 of the type for Swedish Air Force in the beginning of the 1930s. In 1930, Raab-Katzenstein was bankrupt, and Fieseler decided to strike out on his own. Using money he had been saving from his aer ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispano-Suiza 12Y
The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force before the Second World War. The 12Y became the primary French 1,000 hp (750 kW) class engine and was used in a number of famous aircraft, including the Morane-Saulnier M.S.406 and Dewoitine D.520. Its design was based on the earlier, and somewhat smaller, 12X. The 12X did not see widespread use before the 12Y replaced it and became one of the most powerful French designs on the eve of the war. The 12Z was being designed but this was ended by the fall of France and the German occupation. The 12Y was produced under Hispano-Suiza licence in the Soviet Union as the Klimov M-100. This design led to the highly successful Klimov VK-105 series that powered the Yakovlev and Lavochkin fighters as well as the Petlyakov Pe-2 bomber. Licensed production of the early models was also undertaken in Czechoslovakia as the Avia HS 12Ydrs and in Switzerland as the HS-77. Design and devel ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Spanish Civil War
The Spanish Civil War ( es, Guerra Civil Española)) or The Revolution ( es, La Revolución, link=no) among Nationalists, the Fourth Carlist War ( es, Cuarta Guerra Carlista, link=no) among Carlists, and The Rebellion ( es, La Rebelión, link=no) or The Uprising ( es, La Sublevación, link=no) among Republicans. was a civil war in Spain fought from 1936 to 1939 between the Republicans and the Nationalists. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic, and consisted of various socialist, communist, separatist, anarchist, and republican parties, some of which had opposed the government in the pre-war period. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war had many facets and was variously viewed as cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
