Henri Coanda is known mainly for the jet airplane invented in 1910 and during the same year, was presented at the International Aeronautics Exhibition in Paris. Red, without a propeller, with a plaque called "Coanda-1910", with two double wings and a single seat, the plane has raised the interest of all visitors, especially since it was different from what they called "aircraft" until then.
During the exhibition, there was also the first flight with a jet powered engine with the accidental demonstration of Henri Coanda.
While he checked the plane's engine, he took his flight and landed forcefully because Henri lost control. During the test, Henri discovered the "Coanda effect", patented only in 1934, which applies to fans, vacuum cleaners, vacuum pumps, propulsion systems, noise attenuators, compressors, biphasic separators, but also in medicine, the artificial heart.
Throughout his life, Henri Conade has inventions in various fields: aeronautics, construction, transport, industry, medicine, biology, environmental protection. Other inventions: lenticular aerodynamics, seawater desalination plant, cannon-free rebound.
