By late 1910, Henri Coanda flew and and crashed a biplane powered by a motorjet. Although it is debated, this seems to have been the very first piloted flight of a jet in history. Coanda's motorjet incorporated a 50 hp internal combustion engine driving a compressor through a gear box at 4000 rpm. A variable iris ahead of the compressor regulated the flow of air. Airflow proceeded through a ring of combustion chambers to finally be ejected with a force of 220 kg. In all, Coanda's motorjet produced half the thrust of Heinkel's HE 178 which flew decades later.; 12/09/2009 10:26 AM
Mr roT said...: 220 kg doesn't represent a force, Tecs.

Jeez, don't you know any Physics even with your Higgs bundles?; 12/09/2009 3:08 PM
Tecumseh said...: Just shorthand for kilogram-force.; 12/09/2009 3:39 PM
