IPC: F01D5/02

CPC classification number: F01D5/02 ,  F01D5/141 ,  F05D2250/74 ,  Y02E20/16 ,  Y02T50/671 ,  Y02T50/673

Abstract: Turbine frequency tuning, fluid dynamic efficiency, and performance can be improved using a particular airfoil profile, which can be used to determine a throat between adjacent airfoils. By shaping the throat according to the particular profile, the total pressure at an endwall can be energized, improving performance of the turbine.
