Patent ID: 8753087

Claim:
A turbine rotor assembly comprising: a turbine rotor; and a plurality of moving blades implanted in a circumferential direction of the turbine rotor, each of the moving blades forming a flow passage with a circumferentially adjacent moving blade, each of the moving blades having a leading edge on an upstream side of the flow passage and a trailing edge on a downstream side of the flow passage, each of the moving blades comprising: a suction side connecting member protruded on a blade suction surface of the moving blade, the suction side connecting member being formed along the blade suction surface from the leading edge toward the trailing edge, the suction side connecting member having an upstream edge positioned on a tip of the leading edge and a downstream edge positioned on the blade suction surface between the leading edge and the trailing edge; and a pressure side connecting member protruded on a blade pressure surface, the suction side connecting member of each of the moving blades and the pressure side connecting member of the circumferentially adjacent moving blade being configured to form an intermediate connecting member between the moving blade and the circumferentially adjacent moving blade during a rotation of the turbine rotor, wherein a downstream side end edge of the intermediate connecting member is positioned at an upstream side of a throat portion of the flow passage.
