A fixed blade assembly for an axial flow turbine, in which each blade (23) is secured between a radially inner ring (21) and a radially outer ring (22). The trailing edge (25) of each blade is straight and leans at an angle theta away from a radial line (28) from the turbine axis through the inner end of that edge and in the circumferential direction that the suction side (24) of the blade faces. The blades (23) have this (negative) angle of lean in the range 5 degrees to 12 degrees. <IMAGE> |
