We have been developing new long blades with high efficiency and reliability using the advanced design and analysis techniques. Reviewed performance design has been achieved by adopting the best suited transonic profile, taking account of 3D flow and steam effects. High reliability design has been also achieved by adopting an integrally formed cover and a mid-span connecting member. This structure is called as a CCB (Continuous Cover Blade) structure. This paper describes the modern design and analysis techniques, and presents the characteristics of CCB structure. The resonant response analysis and CFD analysis are performed for conventional and CCB structures. The results are compared and discussed.
