The I.Ae. 22 DL was an Argentine advanced training aircraft designed by the Instituto Aerotecnico (AeroTechnical Institute) in 1943, with a wooden structure, which resembled the North American NA-16. ==Development== The I.Ae. 22 DL was a development of the I.Ae. D.L. 21, which itself was itself developed from the North American NA-16, at that time in service with the Argentine military. Argentine experience with the NA-16-4P and deteriorating political relations with the US led to the local development of the I.Ae. D.L. 21, which shared the NA-16 fuselage structure. However it proved too difficult to produce and an entirely new design (the I.Ae. D.L. 22) of similar configuration, but structurally different and optimized to available materials was built instead.〔von Rauch, 1983, pages=14–21〕 It had a wooden structure, and a nine-cylinder 450 HP radial engine (I.Ae. 16 El Gaucho) with a Hamilton Standard 2M-D-30 metallic propeller. The prototype flew the 8 August 1944, although some sources give 14 May 1944. Approximately 200 aircraft were built. A version with an Armstrong Siddeley "Cheetah" 25 engine (radial seven-cylinder, 475 HP) and a Rotol constant speed propeller was designated I.Ae. 22- C. 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「I.Ae. 22 DL」の詳細全文を読む スポンサード リンク
