ABSTRACT:
A trailing edge of a turbine rotor blade is formed so that a deflection angle of a blade surface in a downstream side of a maximum blade thickness portion is a predetermined value or less, by forming the trailing edge of the rotor blade so as to be inclined from a center line of a blade thickness toward an extension line of a suction surface. Since the trailing edge of the rotor blade is thus formed, a rapid increase of the deflection angle is prevented in a trailing edge portion of the rotor blade. Accordingly, a rapid ascent portion and a rapid deceleration portion are not generated in a suction surface velocity in a main stream unlike the conventional case.
