Abstract
A turbine blade has a profile including a blade suction side line, a blade pressure side line, and a blade trailing edge positioned between the rear ends of the blade suction side and pressure sidelines. The blade trailing edge of the profile is formed by connecting a pressure side arc-like curve having a constant radius of curvature and extending from the rear end of the blade pressure side line toward the camber line of the profile, and a suction side line portion which extends from the rear end of the blade suction side line toward the camber line while passing through a region closer to the camber line than a symmetric curve portion which is line-symmetric to the pressure side arc-like curve with respect to the camber line. The suction side line portion is represented by curves constituting ellipses which constitute ellipses, and a straight line.
