  • Airfoil qualification system and method
    Patent number: 6969821
    Abstract: A method for qualifying airfoil blades includes securing an airfoil blade into a fixture, taking digital measurements of the airfoil blade, comparing the digital measurements of the airfoil blade with measurements of a target model, calculating deviations between the digital measurements of the airfoil blade and the measurements of the target model, determining a required treatment for the airfoil blade to conform with the measurements of the target model, directing a reworking system to provide the required treatment to the airfoil blade, and repeating the previous steps until it is determined that no further treatment is required.
    Type: Grant
    Filed: June 30, 2003
    Date of Patent: November 29, 2005
    Assignee: General Electric Company

  • Process for manufacturing deflector plate for gas turbin engine combustors
    Patent number: 6349467
    Abstract: A process for manufacturing components of gas turbine engine combustors, including the steps of performing a plurality of forming steps on a workpiece of a designated material to produce a combustor component of desired size and shape without exceeding a forming limit of the designated material, the forming steps being performed without any intermediate heat treatment on the workpiece.

  • Method and apparatus for peening
    Patent number: 6189356
    Abstract: A mask for masking a corner of a metal component during peening. The component has a first surface defining an opening in the component and a second surface intersecting the first surface of the component at the corner. The mask includes a plug sized and shaped for insertion in the opening adjacent to the corner to cover the corner during peening. Further, the mask includes a rim surrounding at least a portion of the plug sized and shaped for surrounding at least a portion of the opening to cover the corner during peening thereby preventing the corner from being peened.
