Abstract

A turbomachine vane including a plurality of vane sections stacked along a radial axis, each vane section extending along a longitudinal axis between a leading edge and a trailing edge, and along a tangential axis between an active surface and a passive surface, the vane sections being distributed according to longitudinal and tangential distribution laws defining positioning of respective centers of gravity thereof in relation to the longitudinal and tangential axes according to a height of the vane extending from a foot of the vane to a top thereof. Each of the longitudinal and tangential distribution laws involves a change in direction of the slope at between 90% and 100% of the height of the vane.

Claims (11)

1. A turbomachine vane comprising:

a plurality of vane sections stacked along a radial axis, with each vane section extending along a longitudinal axis between a leading edge and a trailing edge, and according to a tangential axis between a pressure surface and a suction surface, with the vane sections being distributed according to longitudinal and tangential distribution laws defining positioning of respective centers of gravity thereof with respect to the longitudinal and tangential axes according to a height of the vane extending from a foot of the vane to a top of the vane,

wherein, in a top section of the vane located between 90 and 100% of the height of the vane

there is a first height starting from which the longitudinal distribution law carries out a first return towards the leading edge of the vane,

there is a second height starting from which the tangential distribution law carries out a second return towards the suction surface of the vane, and wherein the first and second heights are equal.

2. A turbomachine vane according to claim 1 , wherein the first and second heights are between 90% and 95% of the height of the vane.

3. A turbomachine vane according to claim 1 , wherein the vane is made from a metal material.

4. A turbomachine fan comprising a plurality of vanes according to claim 1 .

5. A high-pressure compressor of a turbomachine, comprising a plurality of vanes according to claim 1 .

6. A low-pressure compressor of a turbomachine, comprising a plurality of vanes according to claim 1 .

7. A turbomachine comprising a plurality of vanes according to claim 1 .
