The Caproni Ca.1 was an Italian heavy bomber of the World War I era. ==Development and design== The Ca.1 was a three-engine biplane of fabric covered wooden construction. It had 4 crew members in an open central nacelle: two pilots, a front gunner, and rear gunner-mechanic, who manned upper machine guns, standing upon the central engine in a protective cage, just in front of the rear propeller. The Ca.1 had a tricycle landing gear. Italy and Russia were among the first countries to start developing a heavy bomber capability before World War I. The first heavy bomber, designed by Gianni Caproni was a twin-boom biplane, featuring a layout that included three 67 kW (80 hp) Gnome rotary engines housed one behind the other in a central nacelle, the rearmost driving a pusher propeller, and the other two driving tractor propellers mounted on the fronts of the two booms. Referred to by Caproni as the Caproni 260 hp and retrospectively, after the war, as the Ca.30), this design flew in a slightly modified form (later called the Ca.31) in October 1914. Test flights revealed the power to be insufficient and the engine layout unworkable. Caproni altered the aircraft, retaining the pusher engine in its original location and moving the other two engines to the front of the booms, directly driving the propellers. With more powerful inline engines, the air arm of the Italian Army became interested in purchasing the Caproni 300 hp (later known as the Ca.32), which they designated the Ca.1. A total of 166 aircraft were delivered between August 1915 and December 1916. Some Ca.1s survived the war to be rebuilt as airliners, able to carry up to six passengers. This conversion became known as the Ca.56 in Caproni's post-war naming scheme. There is some variation in published sources over early Caproni designations. The confusion stems, in part, from three separate schemes used to designate these aircraft - Caproni's in-house designations of the time, those used by the Italian Army, and designations created after the war by Caproni to refer to past designs. 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「Caproni Ca.1 (1914)」の詳細全文を読む スポンサード リンク
