Henri Coanda is not important for the simple fact that he made a plane, but for the fact that this very plane managed to revolutionize all the existent concepts up to that moment: it did not have a propeller. There were, of course more prototypes, on cold and thermal propulsions. The results of his research at that time were initially modest, as it usually happened with any one of us, but it was important that he came up with a new idea. Moreover, Henri Coanda’s name is not associated with this field of research only. He was a polyvalent personality. I personally had the chance to meet him and collaborate with him and I appreciated his competences in various areas, regarding both technical issues and general knowledge. He was an enthusiastic supporter of inventors, a zealous person, described by one of his professors as an “eager beaver”. The jet propulsion was not necessarily something new – it had been in place thousands of years ago before Christ: Ezekiel’s cart, Heron of Alexandria, the Chinese or the Mandarins’ inventions -; the novelty consisted of Coanda’s idea of applying it to a flying machine. And it was Henri Coanda’s revolutionary contribution to the future of the jet propulsion in aircraft construction. I could as well compare Coanda with Beethoven, who, in his time, was severely criticized by contemporaries for discrediting the German music school. Similarly, Henri Coanda launched new concepts, namely, the water crystallization systems, containers (tubes), concrete wagons and many other inventions… It is really hard to remind all of his inventions… Coanda involved himself in a multitude of research fields and raised intelligent issues in most of them… Justin Capra Romanian inventor The opening speech delivered at The Polytechnic University Museum, Bucharest June, 8, 2010 |
