Abstract

An optimization design assist system was developed for gas turbine rotor blade design that integrates an optimization algorithm into a workflow automating blade shape creation and aerodynamic and structural analysis. In recent years, thinner blades and higher loads have been used to enhance aerodynamic performance. In view of the impact of increased blade shape design sensitivity on structural mechanics, the system was designed to enhance structural mechanics evaluation functions. This paper presents an overview of the system and example cases of its application to the design of a centrifugal compressor rotor blade and a radial turbine rotor blade. By introducing the system, engineers were able to consider a wide variety of design elements in aerodynamic and structural design, as well as to propose suitable solutions that simultaneously satisfy both aerodynamic and structural design goals and to present quantitative design prospects.
