Abstract
This invention relates an improved cylindrical blades for axial steam turbines comprising a leading edge and a trailing edge and a pressure face and a suction face and an inlet flow angle and an outflow flow angle at the leading edge and trailing edge respectively characterized in that the blades formed by setting angle variation for incompressible flow as well as at subsonic Mach numbers at the exit with a lower loss for a range of stagger angles.
