Patent attributes
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. An airfoil qualification system for performing the method for qualifying airfoil blades includes a measurement station, a data processing system in communication with the measurement station and for determining a point deviation from a surface standard point for each of at least a portion of the plurality of surface points and for determining a required treatment of the airfoil, and a reworking station for directing treatments to the airfoil in response to input from the data processing system.
