Patent ID: 8317482

Claim:
A turbomachine blade comprising: a plurality of blade sections stacked along a radial axis, each blade section extending along a longitudinal axis between a leading edge and a trailing edge and along a tangential axis between a pressure side face and a suction side face, the stack of blade sections being subdivided along the radial axis into a bottom stack, an intermediate stack, and a top stack, the bottom stack extending from a root of the blade to a bottom limit of the intermediate stack, the intermediate stack extending from the bottom limit to a top limit, and the top stack extending from the top limit of the intermediate stack to a tip of the blade, wherein: the projection of a line interconnecting the leading edges of the blade sections of the bottom stack onto a mid-plane formed by the longitudinal axis and the radial axis presents a first longitudinal angle of inclination towards the leading edge that lies in the range 10° to 25° relative to said radial axis; the projection of a line interconnecting the leading edges of the blade sections of the intermediate stack onto the mid-plane presents a second longitudinal angle of inclination towards the trailing edge lying in the range 10° to 25° relative to said radial axis; the projection of a line interconnecting the leading edges of the blade sections of the top stack onto the mid-plane presents a third longitudinal angle of inclination towards the trailing edge that lies in the range 20° to 50° relative to said radial axis; and the bottom limit of the intermediate stack of the blade sections lies between 30% to 40% of the total radial height of the stack of blade sections measured from the root of the blade.
