Siegfried Knemeyer (5 April 1909 – 11 April 1979) was a German aeronautical engineer and aviator. He invented an early flight computer, was the Head of Technical Development for the Reichsluftfahrtministerium during World War II, and invented numerous aviation technologies for the United States Air Force during the Cold War. In the words of his supervisor in the U.S. Air Force, Colonel John Martin, "Kne was a genius in the creation of new concepts in flight control. Many people are good in analysis of ideas after the ideas have been created and presented, but Kne was one of those rare people who could create good ideas, and without exception his ideas proved sound." ==Early career== Knemeyer enrolled at the University of Göttingen in 1927 and studied physics. After one year he left to attend the Technische Universität Berlin, from which he graduated in 1933 with a dual major of theoretical experimental physics and aeronautical engineering. He was affiliated with the Academic Flying Group, with which he became noted as a stunt flyer. Thanks to these exploits the other students nicknamed him "Knall Max" (dynamic Max). Shortly after graduating Knemeyer invented the Dreieckrechner, better known to contemporaries as "System Knemeyer", a flight computer somewhat like the American-invented E6B "whiz wheel" device, that enabled pilots to plan their flight ahead of time and compute the wind triangle for correcting drift in real-time during a flight. "System Knemeyer" was the primary German flight computer for the next decade, through the end of World War II.〔(【引用サイトリンク】work=Sliderulesite )〕 In 1935 Knemeyer was a flight instructor for the Reich Air Ministry, a civilian organization at the disposal of the German military. In this capacity he gave practical flying instructions and technology indoctrination to senior military personnel, including Field Marshal Albert Kesselring, General Walther Wever and Colonel General Ernst Udet, the great World War I flying ace. Kesselring referred to Knemeyer’s abilities flying a Heinkel He 111 as "amazing." Later he was shifted to a more engineering-focused position, where he tested, examined and recommended modifications to aircraft manufacturers based on prototypes they submitted. During the Spanish Civil War Knemeyer served as a test pilot and also observed planes in combat, submitting written reports analyzing their operational attributes and performance. In 1938 Charles Lindbergh visited Germany to inspect war planes, aircraft factories and research laboratories. Knemeyer was Lindbergh’s personal pilot during this visit and guided his tours of the Heinkel factory at Oranienburg, the Junkers factory at Dessau and Magdeburg, the Messerschmitt factory at Augsburg, the Dornier factory at Friedrichshafen, and the central Luftwaffe experimental station at Rechlin, later in the war to be under the command of ''Oberst'' Edgar Petersen. Like many German civilians peripherally serving the military, he resigned his civilian commission and enlisted in the Luftwaffe as a private just after the outbreak of World War II, on 4 September 1939.〔Herwig & Rode 1998, p. 14.〕 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「Siegfried Knemeyer」の詳細全文を読む スポンサード リンク
