  • Methods for correcting twist angle in a gas turbine engine blade
    Patent number: 8122601
    Abstract: A method of correcting a twist angle of a gas turbine engine blade includes measuring an existing twist angle of the blade, applying a first angular load to a first end of the blade; and measuring a repaired twist angle of the blade. The first angular load applied to the first end of the blade is based on an empirical correlation between a plurality of angular loads necessary to produce a plurality of twist angle correction values.
    Type: Grant

  • Method for developing a repair process to correct a deformed gas turbine engine component
    Patent number: 7970555
    Abstract: A method of developing a repair process for a gas turbine engine component deformed during engine operation includes determining peak stress locations in a model of the component, applying loads to sample components based on the model to produce geometrical correction values in the samples, generating data from the samples including the loads applied and the geometrical correction values produced, destructively analyzing the samples at the peak stress locations for structural imperfections, and correlating the loads applied to the geometrical correction values produced to determine allowable loads necessary to produce target geometrical correction values in a used component substantially free of structural imperfections.
