The de Havilland T.K.2 was a British 1930s single-engined monoplane, designed by students of the de Havilland Aeronautical Technical School. It won two races before World War II, and afterwards set a class closed circuit speed record. ==Development== The de Havilland Aeronautical Technical School was set up in 1928, to enhance de Havilland's apprenticeship scheme. From 1933, the students designed aircraft, and the best of these were built. The drawings for the first one were done by a Dutch student, Juste van Hattum who entitled it the T.K.1, with T.K. for "Tekniese Kollege". Three T.K. aircraft were built and flown, the T.K.1, the T.K.2, and the T.K.4. They did not receive DH. style type numbers. The T.K.2 was designed as a high speed tourer, under the leadership of Marcus Langley, the school's instructor in design. It was a single-engined, two-seat low cantilever wing monoplane, with an enclosed cockpit and fixed spatted undercarriage. It first flew on 16 August 1935 at Hatfield Aerodrome, piloted by Hubert S. Broad, and powered by a 147 hp (110 kW) de Havilland Gipsy Major inverted inline engine. Subsequently, for racing purposes, the passenger seat was usually replaced with an additional fuel tank.〔 In late 1935 or early 1936, it received a more aerodynamically refined canopy, and spats extended rearwards. In 1938, it flew with wings clipped by 4 ft (1.22 m) to 28 ft 0 in (8.53 m) and re-engined with a 140 hp (104 kW) de Havilland Gipsy Major II.〔 At the same time, the forward canopy section was revised again, its sides extended downwards below the rear cockpit rim. Post-WWII, it flew with a Gipsy Major 10 engine. The aircraft was not intended for production, and only one T.K.2 was built. It was test flown on various occasions under 'B conditions' with identities E-3, E-5 and E-0235, but otherwise carried the official registration G-ADNO.〔 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「De Havilland T.K.2」の詳細全文を読む スポンサード リンク
