Abstract
The present invention relates to a turbine engine guide () vane (), with a height (H) extending between a vane root () and a vane tip () along a radial direction (Z), said vane () comprising a succession of five bulge portions along a tangential direction (Y) perpendicular to the radial direction (Z), this succession of bulge portions extending over the whole height (H) of the vane (), and the convexity of the successive bulge portions being alternately in one direction and in the other. The vane () has the advantage of having an eigenfrequency for the first striped vibration mode which is different from the urging frequencies of said vane (), during the operation of the turbine engine.
