3DV~(TM) Three-Dimensional Blades - A New Generation of STeam Turbine Blading -

摘要

A new generation of steam turbine blading giving improved performance and highest efficiency is presented. The new bladepath characteristics are a fully three-dimensional blade profile and a variable degree of stage reaction. Advanced numerical optimization algorithms are used to determine the design parameters and to insure that optimal blade shape and degree of reaction are chosen for each individual stage.
