ABSTRACT:
A method of constructing a turbine nozzle with a plurality of nozzle segments minimizes structurally induced excitation forces. The method includes inputting structural characteristics of each of the plurality of nozzle segments, theoretically selecting a random sequencing of the plurality of nozzle segments, calculating a relative harmonic content of per revolution excitation forces of the sequence in accordance with the structural characteristics, theoretically exchanging nozzle segments in pairs to change the sequence of the plurality of nozzle segments, testing the new sequences repeatedly until all possible sequences have been tested, and selecting a sequence that best prevents structurally induced excitation forces. In an alternative embodiment of the invention, the harmonic distortion caused by structural features of a particular unit design is considered as well as the swirl effect that occurs as the gas translates through the turbine. After the best sequence is determined, the nozzle segments can then be placed into the structural casing.
