Description

An axial flow compressor is provided with a rotor blade raw (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).

Ce compresseur axial comporte une rangée d'aubes mobiles (10) disposée de manière qu'une section de sortie est plus grande qu'une section d'entrée afin de réduire la vitesse dans une direction axiale, ainsi que la différence de pression entre une surface de pression positive et une surface de pression négative. En outre, une rangée d'aubes fixes (11) est située en aval de la rangée d'aubes mobiles (10). Une section de sortie de la rangée d'aubes fixes est conçue de manière à être plus petite qu'une section d'entrée de la rangée d'aubes mobiles (10).
