ABSTRACT:
For obtaining a highly compressed air in an axial compressor, a load per blade row must be reduced and blade rows must be increased in number by so much that the apparatus becomes unavoidably larger. The present invention provides an axial compressor stationary blade wherein a blade portion near an end wall face is twisted so as to coincide with a direction of a boundary layer flow occurring in the vicinity of the blade portion. This blade portion and a blade portion for the main flow are turned differently from each other over a distortion or twist angle, and thereby growth of the boundary layer flow is suppressed, an increase of losses is prevented, and the apparatus can be made compact.
