  • Method and apparatus for correcting distortion in gas turbine engine blades
    Patent number: 4087996
    Abstract: Gas turbine engine blades and single-die cavities are dynamically balanced on a rotor, transferred to a neutral atmosphere heated chamber and rotated. The centrifugal force distributes sufficient stress on both the blade's platform and airfoil to correct critical geometrical characteristics by creep forming in a relatively short time. The process is not affected by the blade surface irregularities, which cause die damage in conventional opposed-die forming due to high stress concentrations.
