ABSTRACT:
In a blade lattice structure for an axial fluid machine including circumferentially arranged stationary blades and upper and lower side walls having the stationary blades secured thereto for defining therebetween a flow path which is arranged annularly, the stationary blades each have a cross sectional shape such that the thickness of each stationary blade gradually increases in going toward the upper side wall from an arbitrarily selected position on the blade in its height, so that the area of a throat for each section of the stationary blade is varied along the height thereof to thereby increase stage efficiency.
