Complex simulation procedure to predict flutter of steam turbine rotor blades

Abstract

The need for robust numerical tools to predict the flutter of rotor blades is a crucial aspect of the aeromechanical design of new modern last-stage blades for steam turbines. Therefore, a reliable flutter calculation procedure has been developed and validated in Doosan Skoda Power. As a result, a unique and powerful tool FLTR was developed. It also automates the generation of transient input files and the evaluation described in this paper.
