The present invention is directed to a steam turbine provided with moving blades which are less affected by erosion and fretting wear due to water and have high strength reliability. The moving blades are characterized in that the moving blades are twisted moving blades each provided with a blade portion and a shroud portion formed at its tip, a contact surface between shroud portions connecting adjacent moving blades or an extension plane of the contact surface toward the blade back side which does not intersect with the blade tip of the blade back side shroud portion.
La présente invention concerne une turbine à vapeur utilisant des pales mobiles qui présentent une grande résistance à l'érosion et la corrosion par frottement dues à l'eau, et qui présente aussi la qualité d'une robustesse hautement fiable. Les pales mobiles sont particulières en ce sens qu'elles sont torsionnées, chacune pourvue d'une partie pale et d'une partie voile formée à son extrémité, une surface de contact entre les parties voile joignant des pales mobiles adjacentes ou un plan étendu de surface de contact vers le dos de la pale, qui n'intersecte pas l'extrémité de la partie voile du dos de la pale.
