Abstract:
1. A computer-implemented method of ordering blades in a rotatable machine that includes a plurality of blades that extend radially outwardly from a rotor, said method comprising: receiving at least one geometric parameter measurement of each blade in a row of blades; determining a root sum squared value of a difference of a selected one of the received geometric parameter measurements between adjacent blades in the row of blades; determining a vector sum of a selected other one of the received geometric parameter measurements; determining a moment weight vector sum of each blade to be positioned on the rotor; and determining, using a computer, a sequence map of each blade using the root sum squared value of the difference of the geometric parameter measurement between adjacent blades in the row of blades, the vector sum of a selected other one of the received geometric parameter measurements, and the moment weight vector sum.
