The Etrich ''Taube'', also known by the names of the various later manufacturers who build versions of the type, such as the Rumpler ''Taube'', was a pre-World War I monoplane aircraft. It was the first military aeroplane to be mass-produced in Germany. The Taube was very popular prior to the First World War, and it was also used by the air forces of Italy and Austria-Hungary. Even the Royal Flying Corps operated at least one Taube in 1912. On November 1, 1911, Giulio Gavotti, an Italian aviator, dropped the world's first aerial bomb from his Taube monoplane over the Ain Zara oasis in Libya. Once the war began, it quickly proved inferior as a serious warplane and as a result was soon replaced by newer and more effective designs. ==Design and development== The Taube was designed in 1909 by Igo Etrich of Austria-Hungary, and first flew in 1910. It was licensed for serial production by Lohner-Werke in Austria and by Edmund Rumpler in Germany, now called the ''Etrich-Rumpler-Taube''. Rumpler soon changed the name to ''Rumpler-Taube'', and stopped paying royalties to Etrich, who subsequently abandoned his patent. Despite its name, the ''Taube's'' unique wing form was not modeled after a dove, but was copied from the seeds of ''Zanonia macrocarpa'', which can fly long distances from their parent tree. Similar wing shapes were also used by Karl Jatho and Frederick Handley Page. Etrich had tried to build a flying wing aircraft based on the Zanonia wing shape, but the more conventional ''Taube'' type, with tail surfaces, was much more successful. Etrich adopted the format of crosswind-capable main landing gear that Louis Blériot had used on his Blériot XI cross-channel monoplane for better ground handling. The wing has thee spars and was braced by a cable-braced steel tube truss (called a "bridge", or ''Brücke'' in German) under each wing: at the outer end the uprights of this structure were lengthened to rise above the upper wing surfaces, to form kingposts to carry bracing and warping wires for the enlarged wingtips. A small landing wheel was sometimes mounted on the lower end of this kingpost, to protect it for landings and to help guard against ground loops.〔(The Etrich Monoplane )''Flight 11 November 1911, p.276〕 Later Taube-type aircraft from other manufacturers would eventually replace the Blériot-style crosswind main gear with a simpler V-strut main gear format, and also omitted the underwing "bridge" structure for somewhat better aerodynamic efficiency. Like many contemporary aircraft, especially monoplanes, the Taube used wing warping rather than ailerons for lateral (roll) control, and also warped the rear half of the stabilizer for use as an elevator control surface's function. Only the vertical, twinned triangular rudder surfaces were usually hinged. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Etrich Taube」の詳細全文を読む スポンサード リンク
