Traian Vuia, was a Romanian aeronautical pioneer, from Surducul-Mic<\/a>, then a small village in the Austro-Hungarian Empire<\/a>.\u00a0 Being scientifically minded, he attended the School of Mechanics at the Polytechnic University in Budapest<\/a>.\u00a0 Due to a lack of money, soon he changed to study law so that, concurrent with his education, he could work.\u00a0 Equally brilliant in all subjects, he was awarded a Doctorate in Law with a thesis entitled, \u201cMilitary and Industry, State and Contract Regime\u201d.\u00a0 Yet he remained focused on his work in science and chiefly with one thing, the principles of flight.\u00a0 Hampered from a lack of funding, with his own resources, he would achieve one of Europe\u2019s first aviation triumphs: he would independently create a heavier-than-air flying machine and successfully fly it.<\/p>\n

Portrait of Traian Vuia, Romanian Aviator<\/p><\/div>\n

Yet none of that happened before the scholarly elders at the Acad\u00e9mie des Sciences<\/a> in Paris <\/a>had rejected his research paper submission, which happened on February 16, 1903 \u2014 today in aviation history \u2014 with these famous words, \u201cThe problem of flight with a machine which weighs more than air cannot be solved and it is only a dream.\u201d<\/p>\n

The Paris Experience<\/span><\/strong><\/h4>\n

When Traian Vuia traveled to Paris in July of 1902 to pursue his research into flying, he had done so because within Europe, Paris was considered the center of academical research.\u00a0 He should have traveled rather to Huffman Prairie, but who in the world had heard of those seemingly anonymous bicycle mechanics named the Wright Brothers<\/a>?\u00a0 In Paris he met with Victor Tatin<\/a>, a theoretician and experimenter who, like Vuia, approached the challenges of aviation from a deeply studied perspective.\u00a0 Tatin had developed a model of an airplane and had flown it successfully many years earlier, in 1879.\u00a0 In the ensuing time, he had come to one key conclusion \u2014 that what held man back from flight was not wings nor designs, but rather the low power and oppressive weight of engines.\u00a0 Tatin told Vuia to temper his goals, for such a lightweight engine was still years ahead.
\nConsidering these words, instead Traian Vuia set his mind to engineering a lightweight powerplant of his own design.\u00a0 Though his paper on the principles of taking off into the air had been rejected by the Acad\u00e9mie des Sciences, he nonetheless filed a patent on his research, which was awarded in August 1903. His powerplant research similarly pursued scholarly grounds, with numerous bench tests.\u00a0 His engine relied on liquid carbon dioxide which was vaporized in a Serpollet boiler<\/a>.\u00a0 This gave him a three minute fuel supply at high power \u2014 it was a revolution.<\/p>\n

What held him back from going directly into flight experiments, however, was simply a lack of funds.\u00a0 Nonetheless, he started to build his airplane in his small workshop in Paris.\u00a0 He could only afford to proceed in fits and starts.\u00a0 Few with money, it seemed, would back a dream of flight, despite the public\u2019s interest in the subject.\u00a0 Above, he believed his own conclusion that flight could be achieved safely and reasonably, as he had written in his rejected paper:
\n\u201cL\u2019a\u00e9roplane-automobile est capable d\u2019avancer sur le sol comme une automobile ordinaire et ne monte qu\u2019\u00e0 la hauteur voulue par le pilote lui-m\u00eame\u2019 celui-si peut en effect, s\u2019il le veut, avancer\u00a0\u00e0 la hauteur de quelques centimetres seulement au-dessus du sol, et par cons\u00e9quent les exp\u00e9riences pourront \u00eatre faites sans danger par toute personne sachant conduire une automobile.\u201d
\nTranslation:\u00a0 The airplane is capable of accelerating on the ground like an ordinary car and only rises to the height desired by the pilo, so he can effect, as he desires, to achieve a\u00a0 height of a few centimeters just above the ground, and therefore experiments can be done safely by anyone who can drive a car.<\/p>\n

\u00a0The Traian Vuia 1<\/span><\/strong><\/h4>\n

From an unlikely beginning on a shoestring budget, the Traian Vuia 1 emerged by Vuia\u2019s own hands.\u00a0 What could have taken him just a year instead had required nearly two and a half years of slow construction.\u00a0 He had scrabbled together the funds to buy the fabrics, braces, wheels and tires and mechanical parts of his own flying machine.\u00a0 At the end of December 1905, he was ready to begin controlled experiments.\u00a0 By then, though he didn\u2019t know it, it was already two years since the Wrights had flown at Kitty Hawk, though like most Europeans, he did not trust the news and rumor of such faraway events.
\nHe called his aircraft the \u201cAirplane-Car\u201d.\u00a0 He had pioneered a four wheel, light weight frame in which he sat to drive it forward by the force of its tractor propeller above and ahead.\u00a0 The engine was mounted atop his head for easy access, with that and himself being positioned at the center of gravity underneath the wings, which were mounted with a roughly 15 degree positive angle of attack to the ground when the four wheels were not lifted.
\nHis principles of take off were drawn from the original scholarly paper that the Acad\u00e9mie des Sciences had rejected and had presupposed speed and angle of attack<\/a> in a relationship that produced a known amount of lift against a defined wing area.\u00a0 This flying machine would be driven forward at ever increasing speed based on the thrust from the propeller.\u00a0 Then, when the wind speed had achieved a certain point across the fabric covered wing, he had theorized that the plane would simply lift off into the air.\u00a0 It was a classic concept and one which remains still in use today.<\/p>\n

The First Flight<\/span><\/strong><\/h4>\n

At Montesson<\/a>, a small town in the countryside near to Paris, he drew up his machine for his first flight test.\u00a0 It was March 18, 1906.\u00a0 First motoring back and forth to gain familiarity with the machine on the ground with the wings removed, he grew confident in its ground handling.\u00a0 In fact, here Vuia had also invented the modern taxi test, which is de rigour for every aircraft design today.\u00a0 Satisfied, he mounted the wings.\u00a0 Climbing into the cockpit after refueling the engine, he was ready to try flight.
\nHe triggered the engine to life.\u00a0 With the large tractor blades of the propeller, the machine accelerated rapidly.\u00a0 Just 50 meters down the path, he had achieved the speed necessary to lift off.\u00a0 Exactly as predicted based on the angle of the wing, the machine simply lifted off from the ground.\u00a0 It rose to about 1 meter in height.\u00a0 He shut off the engine and the plane gently set back on the ground, landing almost instantly.
\nFrom take off to landing, he had managed a distance of 12 meters aloft \u2014 yet he had flown!\u00a0 The test was perfect in every respect!<\/p>\n

 <\/p>\n

Final Thoughts<\/strong><\/span><\/h4>\n

Incredibly, Traian Vuia\u2019s airplane did not cause the sensation it should have.\u00a0 While others who followed, including Santos-Dumont<\/a>, who had followed Vuia\u2019s work closely and benefited immensely, they would become superstars in the Parisian public eye.\u00a0 Yet while Santos-Dumont and others would attain fame, Vuia had done something that few others had achieved \u2014 completely on his own, he had pioneered an original route to the air.\u00a0 What\u2019s more, unlike the others, he had done it on a shoestring based just on the power of his intellect, the work of his own hands and the strength of his dream.
\nOver the next couple of years, Traian Vuia would develop other aircraft and refinements of his design, but his efforts were ultimately a dead-end.\u00a0 Others made more rapid advances, gained funding and investment and flew.\u00a0 While Traian\u2019s flight had been extraordinary, it still lacked a working flight control system.\u00a0 He may have taken off and landed, but it was a limited type of flight with no way of achieving a turn, a climb or a dive.
\nYet still, in those first heady years of the 1900s, Traian Vuia\u2019s flight was truly a great achievement!<\/p>\n
