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.
