ABSTRACT:
A method is disclosed for evaluating a damaged blade in a compressor or turbine using a computer system accessing a database of blade repair information, where the method includes: selecting a blade damage geometry category corresponding to the damage of the blade from a plurality of blade damage geometry categories; measuring the blade damage, and generating a repair geometry for the blade based on the blade damage measurements and the selected blade damage geometry category.
