The Coanda-1910 was the first jet-propelled aircraft ever built. It was constructed by Romanian inventor Henri Coand? and exhibited by him at the Second International Aeronautical Exhibition in Paris around October 1910.

The aircraft was quite unconventional in design, and its most striking feature was its powerplant, since it featured a kind of thermojet, a hybrid of jet engines and piston engine technology. This used an ordinary internal combustion engine to drive a compressor instead of a propellor. The compressed air was mixed with fuel and ignited in two combustion chambers before being exhausted along the sides of the aircraft. This was intended to provide a reactive force that would push the aircraft along.

Unfortunately during a ground test of the engine on December 16, 1910, Coand? was caught unaware by the power of the engine and found himself briefly airborne. He lost control of the machine, and it crashed, burning, to the ground. Coand? was thrown clear of the crash.

During the machine's short flight, Coand? was able to observe that the burning gasses from the engine seemed to hug the sides of the aircraft very closely and this is what seemed to cause the fire. He (and other scientists) spent many years researching this effect, which is now known as the Coanda Effect in his honour.

Coand? did not pursue this line of development of the jet engine. However, years later, the Italian Campini Caproni CC.2 aircraft would fly with a similar type of engine, and Japanese engineers would develop another such engine to power kamikaze aircraft. However, practical jet engines depended on the development of the turbojet to become a reality.
