METHOD FOR DESIGNING TURBO-MACHINE BLADES, SPECIFICALLY GAS TURBINE AND STEAM TURBINE BLADES

摘要

A method for designing turbo-machine blades includes: determining primary fluid-dynamic data (FDS) related to a plurality of first blade sections (S1, S2,..., SK); determining structural data (SDS); and correlating fluid-dynamic data (FDS) to corresponding structural data (SDS). Furthermore, correlating fluid- dynamic data (FDS) to corresponding structural data (SDS) includes: determining interpolated fluid-dynamic data (FDS' ), related to a plurality of second blade sections (SINTH) interposed between corresponding first blade sections (S1, S2,..., S?), starting from primary fluid-dynamic data (FDS); defining a modified fluid- dynamic data set (FDS"), including both primary fluid- dynamic data (FDS) and interpolated fluid-dynamic data (FDS' ); and associating modified fluid-dynamic data (FDS") to corresponding structural data (SDS).
