In the power industry Rateau is remembered primarily for his steam turbine. Rateau is credited with the invention of the pressure stage impulse turbine. He restricted the expansion of steam to the nozzles but used larger pressure drops per stage. In his design the rotors were separated by diaphragms which contained the nozzles. This reduced the number of stages for a given power output and shortened the distance between bearings. The Rateau turbine has been dated at 1901; the U.S. patent was issued in 1903. His turbine found wide acceptance in both marine and central station applications. The use of a single Curtis wheel, followed by a number of Rateau stages, characterized General Electric Company practice in the United States over the succeeding half-century. The combination is still widely used today. As early as 1900 Rateau was interested in the problems associated with aviation. He studied aircraft performance, wing sections, and aircraft propellers, confirming his calculations with wind tunnel tests. Although Rateau did not invent the turbosuper-charger, he was perhaps the first to apply it to aircraft engines (1916–1917). He investigated the effect of the supercharged engine on the range and altitude capabilities of airplanes.
