Patent abstract

An axial flow compressor is provided with a rotor blade row (10) which is formed such that an outlet cross sectional area is larger than an inlet cross sectional area so as to reduce a speed in an axial direction and reduce a pressure difference between a positive pressure surface and a negative pressure surface. Further, a stator blade row (11) is provided in a downstream side of the rotor blade row (10). An output cross sectional area of the stator blade row (11) is structured such as to be smaller than an inlet cross sectional area of the rotor blade row (10).
