Abstract: A turbomachinery includes a casing, a rotor shaft rotatably attached to the casing, a first blade row fixed to either one of the rotor shaft or the casing, and a second blade row fixed to either one of the rotor shaft or the casing and arranged adjacent to the upstream side or downstream side of the first blade row, wherein the turbomachinery sets the number of first blades and the number of second blades in a manner that the interblade phase angle difference of the second blade row is ±180°.

Abstract: In an axial compressor including a row of rotor blades (70) provided on a rotational shaft (20) around a central axial line of the rotational shaft at a prescribed pitch, and a row of stator vanes (40) provided on a casing around the central axial line at a prescribed pitch so as to adjoin the row of rotor blades on an upstream or downstream side thereof, the rotor blades each extend along a radial line (R) emanating from the central axial line, and the stator vanes each extend along a slanted line (I) that is slanted with respect to a corresponding radial line in a circumferential direction.
