Abstract

See full text

A rotor blade (22) provided in an axial flow compressor (1) including a rotating shaft, a casing (3), a diffuser portion (4) provided on a downstream side of the casing to communicate with a flow path (C) of the casing and form an annular shape and configured to define a diffuser flow path (DC) in which a cross-sectional area of the flow path expands toward the downstream side, a plurality of stator vane rows (10), and rotor blade rows (20) performing compression of a gas. A plurality of rotor blades are spaced apart from each other in a circumferential direction, and constitute a final rotor blade row (20A) positioned on a most downstream side among the rotor blade rows, and include a blade portion (25) having a larger deflection angle on a hub side and a chip side than at a central portion in a blade height direction.
