Abstract: A water-cooled rotor for a large turbine generator in which the rotor passages are protected against corrosion by liners of stainless steel or other corrosion resistant material. In order to reduce the stresses in the liners due to differential thermal expansion, the liners are prestressed in tension against a concentric outer tube.
