Traian Vuia or Trajan Vuia ((:traˈjan ˈvuja); August 17, 1872 – September 3, 1950) was a Romanian inventor and aviation pioneer who designed, built and tested a tractor configuration monoplane. He was the first to demonstrate that a flying apparatus could rise into the air by running upon wheels upon an ordinary road. He is credited with a powered hop of made on March 18, 1906 and he later claimed a powered hop of .〔.〕〔Angelucci,E. and Matricardi, P.; "World Aircraft: Origins–World War 1", Sampson Low (1977).〕 Though unsuccessful in sustained flight, Vuia's invention influenced Louis Blériot in designing monoplanes. Later, Vuia also designed helicopters. A French citizen since 1918, Vuia was also a great patriot, leading the Romanians (especially Transylvanians) of France in the resistance during World War II. He returned to Romania in 1950. ==Education and early career== Vuia was born to Romanian parents Simion Popescu and Ana Vuia living in Surducul-Mic, a village in the Banat region, Austro-Hungarian Empire, today in Romania; the place is now called Traian Vuia. After graduating from high school in Lugoj, in 1892, he enrolled in the School of Mechanics at the Polytechnic University of Budapest where he received his engineering diploma. He then joined the Faculty of Law in Budapest, Hungary, where he earned a Ph.D. in law in May 1901 with the thesis "Military and Industry, State and Contract regime".〔.〕 He returned to Lugoj, where he studied the problem of human flight and designed his first flying machine, which he called the "airplane-car". He attempted to build the machine, but due to financial constraints decided to go to Paris in July 1902, hoping to find someone interested in financing his project, possibly balloon enthusiasts. He met with considerable skepticism from people who believed that a heavier-than-air machine could not fly. He then visited Victor Tatin, the well-known theoretician and experimenter who had built an aircraft model which flew in 1879. Tatin was interested in the project, but doubted that Vuia had a suitable engine or that his aircraft would be stable. Vuia then presented his plan to the Académie des Sciences in Paris on February 16, 1903, but was rejected with the comment: "The problem of flight with a machine which weighs more than air can not be solved and it is only a dream." Undeterred, Vuia applied for a French patent on May 15, 1903, and obtained patent No. 332106 for his design.〔.〕〔 He began to build his first flying machine in the winter of 1902–3. Overcoming more financial difficulties, he also started construction of an engine of his own design for which he was granted various patents, the first in 1904.〔(Traian Vuia - a Century of Aviation )〕〔(Romanian Aviation Pioneers ) Romainian Coins〕 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「Traian Vuia」の詳細全文を読む スポンサード リンク
