摘要： A turbine moving blade has a blade portion extending from the basal portion to the tip of the moving blade. The blade root portion is formed at the basal portion of the blade portion and engaged with a corresponding disk groove of a turbine rotor on a one-by-one basis, and the integral cover is formed at the tip of the blade portion integrally with the blade portion. The integral cover includes at least a pair of pressure and suction sloped surfaces inclined relative to the direction of the rotational axis of a turbine so as to restrain the elastic restoring force of the moving blade torsionally deformed at the time of installation of the moving blade by bringing the integral covers of mutually adjacent blades into contact.

摘要： A set of turbine rotor blades is arranged on a rotor disk. Each rotor disk has blade profile, root parts which is fitted axially in an axial disk groove formed circumferenctially in the rotor disk, and an integral cover formed at the outer edge of the blade profile part. A front end surface, faced in a direction the rotor disk rotates, of the integral cover is inclined to a direction in which the root part of the turbine rotor blade is fitted in the disk groove of the rotor disk. The sum of circumferential lengths of the integral covers is greater than a circle at which the integral covers are joined to the blade profile parts. Adjacent integral covers are brought into contact with each other by the blade profile parts that are twisted when root parts of the turbine rotor blades are fitted axially in the disk grooves.

摘要： The invention is intended to reduce the profile loss. For that purpose, according to the invention, a plurality of turbine blades are arranged in the circumferential direction of a turbine driven by a working fluid. Each of the turbine blade is formed such that the curvature of a blade suction surface, which is defined by the reciprocal of the radius of curvature of a blade surface on the blade suction surface side, is decreased monotonously from a blade leading edge defined as the upstream-most point of the blade in the axial direction toward a blade trailing edge defined as the downstream-most point of the blade in the axial direction.
