# Optimization of Gas Turbine Compressor Blade Parameters for Gas-dynamic Efficiency under Strength Constraints

### Leonid Shabliy, Aleksandr Cherniaev

#### Abstract

This article describes an approach for optimization of gas turbine compressor blade based on one-way fluid-structure interaction (FSI) analysis coupled with evolutionary optimization algorithm. Commercial CFD and FE code ANSYS was used for the simulations. Paper gives detailed description of developed geometric model, CFD and FE models, as well as description of employed optimization technique. Obtained results indicate that adiabatic efficiency and pressure rate of compressor can be increased up to 23% and 7% correspondingly by rational selection of relative positions of compressor blade cross-sections.
