ROTOR BLADE FOR AXIAL-FLOW TURBINE

摘要

A rotor blade for an axial flow turbine is provided to improve efficiency of a turbine and thrust by enhancing the shape of a leading edge of a blade. A rotor blade for an axial flow turbine, comprises an intrados(2) for producing positive pressure between a leading edge and a trailing edge; and an extrados(1) for producing negative pressure between the leading edge and the trailing edge. The intrados and the extrados at the leading edge are chamfered so that the intrados and the extrados are connected through a plane(3). The angle between the chamfered intrados and the chamfered extrados is smaller than the angle between the chamfered intrados and a vertical plane including the leading edge.
