Abstract

A compressor stator vane unit (22) includes multiple compressor stator vanes (31) disposed at a certain interval in a circumferential direction; and an annular joint member (32) connected with inner ends of the multiple compressor stator vanes; wherein the annular joint member constitutes an outer diameter side surface of a leakage fluid flow path (37) provided in an inner diameter side of the joint member to communicate a high-pressure space with a low-pressure space respectively located downstream and upstream of the multiple compressor stator vanes in a fluid flow direction, and D / P is setto 0.05 <= D / P <= 0.2, wherein D is defined as a distance in an axial direction between an upstream end surface of the annular joint member and an upstream edge of the multiple compressor stator vanesin the fluid flow direction and P is defined as a pitch between the adjacent compressor stator vanes in the circumferential direction.

Description

technical field [0001] The present invention relates to a stator blade unit in which stator blades are arranged at predetermined intervals in a circumferential direction, a compressor including the stator blade unit, and a gas turbine including the compressor. Background technique [0002] A gas turbine consists of a compressor, a combustor, and a turbine. In the compression mechanism, a plurality of stator blades and a plurality of rotor blades are alternately arranged inside the casing. A plurality of stator blades are arranged at predetermined intervals in the circumferential direction, and their outer ends are fixed to the inner peripheral surface of the casing. A plurality of rotor blades are arranged at predetermined intervals in the circumferential direction, and inner ends are fixed to an outer peripheral portion of a rotor rotatably supported by a casing. In addition, an annular shroud is fixed to the inner end of the plurality of stator blades, and a sealing devi...
