  • Low friction fluid bearing and turbine using same
    Patent number: 6179554
    Abstract: A low friction bearing comprises a first element having a first surface. A second element having a second surface is rotatable about a centerline relative to the first element. A flow passage extends radially outward between the first surface and the second surface. The first surface and the second surface are separated by a fluid flow. The two surfaces are complementary and positioned in close proximity. The bearing finds a preferred application in a fluid cooled turbine to create a high temperature, high efficiency turbine.
