Henri Coand\u0103 (7 June 1886 \u2013 25 November 1972) was a Romanian inventor, aerodynamics pioneer, and builder of an experimental aircraft, the Coand\u0103-1910 described by Coand\u0103 in the mid-1950s as the world’s first jet, a controversial claim disputed by some and supported by others. He invented a great number of devices, designed a „flying saucer” and discovered the Coand\u0103 effect of fluid dynamics.<\/p>\n

Henri Coanda attended high-school in Bucharest and in Iasi. After this he joined the Bucharest Military School where he graduated as an artillery officer. Fond of technical problems, especially of flight technics, in 1905 he built a \u2018missile-airplane\u2019 for the Romanian Army. Then he went up to Berlin to attend studies at Technische Hochschule in Charlottenburg, after which he followed with studies at the Science University in Liege, part of the Electrical Institute in Montefiore(1907-1908), where he met Gianni Caproni. In 1908 Coand\u0103 returned to Romania to serve as an active officer in the Second Artillery Regiment. However, his inventor\u2019s spirit did not comport well with military discipline. He solicited and obtained permission to leave the army, after which he took advantage of his renewed freedom to take a long automobile trip to Isfahan, Teheran, and Tibet. Upon his return in 1909, he travelled to Paris, where he enrolled in the newly founded \u00c9cole Nationale Superieure d\u2019Ingenieurs en Construction A\u00e9ronautique. One year later (1910) he graduated at the head of the first class of aeronautical engineers.<\/p>\n

With the support of engineer Gustave Eiffel and the mathematician, politician, and aeronautical pioneer Paul Painlev\u00e9, he began experimenting the aerodynamic techniques: one of this experiments was mounting a device on a train running at 90 km\/h so he could analyse the aerodynamic behavior. Another experiment used a wind tunnel with smoke and an aerodynamical balance to profile wings to be used in designing aircraft. This later led to the discovery of the aerodynamic effect now known as the Coand\u0103 effect.<\/p>\n
