Abstract:
1. A method for testing turbine blades, comprising: measuring dimensions of each of a first plurality of turbine blades; testing airflow through a first plurality of openings in each of the first plurality of turbine blades to determine airflow properties of each of the first plurality of turbine blades; determining a relationship between the dimensions and the airflow properties of each of the first plurality of turbine blades by performing a principle component analysis; measuring dimensions of each of a second plurality of turbine blades; and determining airflow properties for each of the second plurality of turbine blades based at least partially on the dimensions of the second plurality of turbine blades and the relationship, wherein determining the relationship comprises correlating a set of locations of each turbine blade along each axis of a principle component coordinate system with one measured airflow property of each turbine blade and deriving a functional relationship between the locations and the measured airflow properties.
