The Short Type 320, also known as the Short Admiralty Type 320,〔("Royal Air Force Museum Aircraft Thesaurus" ) archived from the original at ()〕 was a British two-seat reconnaissance, bombing and torpedo-carrying "folder" seaplane of the First World War. ==Design and development== The Short Type 320 was designed to meet an official requirement for a seaplane to carry a Mark IX torpedo. It was larger than the earlier Short 184, and was a typical Short folder design of the time, with two-bay uneven span wings. Two prototypes were built, powered by a 310 hp Sunbeam Cossack engine, and initially known as the Short 310 Type A from the engine fitted to the prototypes. When the torpedo bomber went into production, it was powered by a 320 hp (238 kW) Cossack engine which was the origin of the name the Type 320.〔(Bruce ''Flight'' 28 December 1956, p. 1002 )〕 At the same time as Shorts was designing the 310 Type A torpedo bomber, it produced a similar design for a patrol floatplane, powered by the same Cossack engine and using the same fuselage, but with equal span three-bay wings instead of the uneven span wings of the torpedo bomber, known as the Short 310 Type B or North Sea Scout, and two prototypes were ordered.〔Barnes 1967, p. 130〕〔Bruce, ''British Aeroplanes 1914-18'', pp. 502-503〕 Priority was given to the torpedo bomber; the first was ready in July 1916, and the second in August that year, and the prototypes were rushed to the Adriatic.〔Barnes 1967, pp. 130-131〕 In September 1916, the first prototype patrol aircraft was finished, but it proved to be little better than the Short 184 already in service, and was not ordered into production.〔Barnes 1967, p. 133〕 The second prototype Type B was completed as a type A torpedo bomber.〔Barnes 1967, p. 132〕 As with conventional biplane floatplanes, the torpedo was carried between the bottom of the fuselage and the floats. Unusually, the aircraft was flown from the rear cockpit, although this did cause a problem for an observer in the front seat. The observer had to stand on the coaming to use the machine-gun, which was level with the top wing. When a torpedo was carried, the aircraft could not fly with an observer at the same time.〔(Bruce ''Flight'' 28 December 1956, p. 1003 )〕 The first order placed with Shorts was for 30 aircraft, followed by orders for a further 24 and 20 aircraft, together with orders for a further 30 and 20 placed at Sunbeam. Together with the three prototypes, this gave a total production of 127 Short Type 320s.〔Barnes 1967, pp. 132-133〕 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「Short Type 320」の詳細全文を読む スポンサード リンク
