Henri Coandă

Henri Coanda, a Romanian inventor, aerodynamics pioneer and builder of an experimental aircraft was born in 1886, in Bucharest, Romania.. Coanda graduated with the rank of artillery officer, but he was more interested in the technical problems of flight. In 1905, he built a missile airplane for the Romanian Army. In 1910, he designed, built and piloted the first jet plane, known as the Coanda-1910, which he exhibited at the second International Aeronautic Salon in Paris. As technical director of Bristol Aeroplane Company (1911-1914) in the United Kingdom, where he designed several airplanes known as Bristol-Coanda Monoplanes. In 1912, one of these planes won the first prize at the International Military Aviation Contest in the UK. In 1915, he worked for Delaunay-Belleville in France, where he designed and built three different models of propeller airplane, including the Coanda-1916, with two propellers mounted close to the tail. Other significant inventions were a construction material known as beton-bois, a device for detecting the liquids in the soil, a mobile platform for aerodynamic experiments, photographic aerodynamic specters. In 1930, he discovered the Coanda effect that is the tendency of a stream of fluid to stay attached to a convex surface, rather than follow a straight line in its original direction. On October 8, 1934, he got the patent for the invention called “Procedure and device for the deviation of a fluid inside another fluid”. In 1935, he designed the Aerodina Lenticulara, which was very similar in shape with what is
