| 摘要 |
The invention relates to a turbomachine blade comprising a plurality of blade sections stacked along a radial axis, and in which the projection of a line interconnecting the leading edges of the blade sections of the bottom stack onto a mid-plane presents a first longitudinal angle of inclination towards the leading edge that lies in the range 10° to 25°, the projection of a line interconnecting the leading edges of the blade sections of the intermediate stack presents a second longitudinal angle of inclination towards the trailing edge lying in the range 10° to 25°, the projection of a line interconnecting the leading edges of the blade sections of the top stack presents a third longitudinal angle of inclination towards the trailing edge lying in the range 20° to 50°, and the bottom limit of the intermediate stack of the blade sections lies in the range 30% to 40% of the total radial height of the stack of blade sections.
