The rotating blade has been developed for small and mid-class steam turbines with a short blade height. The blade is designed using Taguchi method combined with 2-D turbulent flow analysis and the inverse method. The blade configuration is expressed by four control factors, which are turning angle, leading edge radius, pitch-chord ratio and maximum blade loading location. The verification tests are performed by the linear cascade experiments and 3-D stage analysis. Consequently, the blade has a blunt-nose, flat incidence characteristics and low energy loss, compared with the conventional one and it is found that the optimal condition given by Taguchi method is aerodynamically reasonable.
