An overview of modern methods for optimal design of hydroturbine blading systems is presented. Previously proposed system for automatic optimal design of Francis turbine runner is generalized by implementing a parameterization for blade thickness. The problem of simultaneous improvement of several characteristics of the turbine flow passage at specified operation regimes is considered. As an example, the problem of designing a runner with high efficiency characteristics at best efficiency point and a low level of pressure pulsations caused by vortex rope precession at part-load regime, is solved. In order to verify the obtained results, unsteady vortex rope simulations are carried out for initial and the optimal runner designs.
