Turbine engine guide vane

A turbine engine guide vane 25 has a succession of five bulge portions along a tangential direction Y perpendicular to a radial direction Z. The bulge portions extend over the whole height H of the vane between a vane root 26 and vane tip 27. The convexity of successive bulge portions is alternately...

Zusammenfassung:	A turbine engine guide vane 25 has a succession of five bulge portions along a tangential direction Y perpendicular to a radial direction Z. The bulge portions extend over the whole height H of the vane between a vane root 26 and vane tip 27. The convexity of successive bulge portions is alternately in one direction (e.g. towards a suction side 30 of the vane) and then the other (e.g. towards a pressure side 31). An eigenfrequency for the first stripe vibration mode is different from the urging frequencies of the vane during the operation of the turbine engine.
