Coanda 1910 Free low-poly 3D model

The Coandă-1910, designed by Romanian inventor Henri Coandă, was an experimental plane powered by a ducted fan. Built as a sesquiplane, it featured an experimental aircraft engine which Coandă called the "turbo-propulseur", having a multi-bladed centrifugal blower driven by a conventional piston engine and exhausting into a duct. The unusual aircraft attracted attention at the Second International Aeronautical Exhibition in Paris in October 1910, being the only exhibit without a propeller, but the aircraft was not displayed afterward and it fell from public awareness. Coandă used a similar turbo-propulseur to drive a snow sled, but he did not develop it further for aircraft. (Wource Wikipedia)
