An optimal method for the aerodynamic design of cascades based on vortex modification

A set of numerical calculation methods and correspondent software are developed for the optimized design of turbo cascade profiles. The calculations for the direct and inverse problems are carried out alternatively and aerodynamic analysis is emphasized as a direction of cascade design. The application examples show that the profile loss of cascades can be reduced effectively with this design method.
