Turbines

Turbines

are rotating machinery for extracting mechanical or electrical energy from steam, from burning natural gas and oil, and from moving water including tides and hydroelectric dams. Biggest turbine uses are in generating electricity, powering aircraft, driving the propellers of nearly all large seagoing vessels. Turbine rotor and stator blades (airfoils), disks, and seals place severe demands on the science of high-temperature materials, on component manufacturing and on quality assurance.
