Rotor and blades. Photo: Steam turbine blades look a bit like propeller blades but are made from high-performance alloys because the steam flowing past is hot, at high pressure, and traveling fast. Photo of a turbine blade exhibited at Think Tank, the science museum in Birmingham, England.
The first practical steam turbines were made by Gustaf de Laval 1882 and Charles Parsons in the 1884. Diagram of de Laval's Steam Impulse Turbine 1882. Steam enters on one side of the turbine rotor through the nozzles, pointing at the surface of the turbine blades, and leaves from the opposite side of the rotor. The impact of the steam on the curved turbine blades causes the turbine rotor to turn. The speed of rotation was 30,000 r.p.m.
