Henri Coanda, aviation pioneer, physicist, inventor of the jet engine and also the discoverer of the effect which bears his name today.

The child passionate about the wind, born on 7 June 1886, was to become an aeronautics pioneer, although in the early years he proved himself to be a mediocre student, being about to fail at math. However, exceptional teachers, such as G. Ibraileanu and A. D. Xenopol, helped him to discover his passion for the technical field.

After finishing high school in 1903, he experienced the rigors of the Artilery Officers and Marine Engineering School of Bucharest, then he left for Germany, where he obtained his PhD in engineering sciences at Technische Hochschule, Charlottenburg. Finally, he left the army, which did not fit his spirit, and this time went to France, where he entered the Superior School of Aeronautic. Coanda gratuated it in the next year as valedictorian and then begins his career, with the famous French engineer Gustave Eiffel, to whom he will tie a close friendship later.

In 1910 he created and tested the first jet aircraft in the world - called "Coanda 1910", which he presented at the International Aeronautics Exhibition, in Paris. In the same year, he noticed a phenomenon that was to be called the "Coanda effect", which is actually the invention that made him famous. The discovery will be patented later, in 1934, under the name "Method and device for deflecting a fluid in another fluid"

Over his entire career, Henri Coanda was the author of 250 patents in various fields, receiving also honorary titles, including the membership at the Royal Aeronautical Society of London and the membership at the Romanian Academy. He also received the title of Doctor Honoris Causa at the Polytechnic Institute of Bucharest, where he reorganised the aeronautical engineering catedra, in 1971, with help from the academician Elie Carafoli.

Henri Coanda died in 1972, on November 2, but be left behind years of work and passion that have served and will serve as inspiration to posterity, but he left especially the memory of a leading personality of the universal science and particularly aviation.
