The Aerial Experiment Association (AEA) was a Canadian-American aeronautical research group formed on 30 September 1907, under the leadership of Dr. Alexander Graham Bell.〔Milberry 1979, pp. 12–13.〕 The AEA produced several different aircraft in quick succession, with each member acting as principal designer for at least one. The group introduced key technical innovations, notably wingtip ailerons and the tricycle landing gear. According to Bell, the AEA was a "co-operative scientific association, not for gain but for the love of the art and doing what we can to help one another."〔Milberry 1979, p. 13.〕 Although the association had no significant commercial impact, one of its members, Glenn Curtiss, later established a large and successful aeronautical manufacturing company. The AEA was disbanded on 31 March 1909. ==Origins== The AEA came into being when John Alexander Douglas McCurdy and his friend Frederick W. "Casey" Baldwin, two recent engineering graduates of the University of Toronto, decided to spend the summer in Baddeck, Nova Scotia. McCurdy had grown up there, and his father was the personal secretary of Dr. Bell. He had grown up close to the Bell family and was well received in their home. One day, as the three sat with Dr. Bell discussing the problems of aviation, Mabel Bell, Alexander's wife, suggested they create a formal research group to exploit their collective ideas. Being independently wealthy, she provided a total of US$35,000 (approximately $ in current dollars) to finance the Association, with $20,000 made available immediately by the sale of property.〔Gillis, Rannie.

Retrieved: 24 February 2012.〕〔Toward 1984, pp. 141–155.〕 Curtiss, the American motorcycle designer and manufacturer and a recognized expert on gasoline engines, was recruited as a member of the association. Curtiss had visited the Wright brothers to discuss aeronautical engineering and offered them use of a 50 hp engine. Wilbur cordially declined, saying that a motor of their own development met their power needs, unaware that the AEA was about to become a serious competitor in powered flight. Bell wrote to U.S. President Theodore Roosevelt to have an interested young officer who had volunteered his help, US Army Lieutenant Thomas Selfridge, officially detailed to Baddeck. Selfridge was assigned to the Aeronautical Division, U.S. Signal Corps on 3 August 1907, two days after its formation, and was sent to Nova Scotia. A year later, on 17 September 1908, while riding as a passenger with Orville Wright on a demonstration flight for the U.S. Army, he became the first person killed in an aircraft accident. 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「Aerial Experiment Association」の詳細全文を読む スポンサード リンク
