Zusammenfassung:PROBLEM TO BE SOLVED: To provide a steam turbine rotating blade (20) for a low-pressure section of a steam turbine engine (10). SOLUTION: The steam turbine rotating blade (20) includes a blade-shaped section (42). A root section (44) is fitted to one end of the blade-shaped section (42). A tab tail section (40) includes a slantwise shaft direction inserting type tab tail that is a tab tail section (40) protruding from the root section (44). An apical end section (46) is fitted on the blade-shaped section (42) in an end opposite to the root section (44). A cover (48) is formed integrally with the apical end section (46) as a part of the apical end section (46). The rotating blade (20) includes an annular outlet space area not smaller than about 30.5 ft2(2.83 m2). COPYRIGHT: (C)2010,JPO&INPIT
