A vane configured to be placed with a plurality of identical vanes so as to form a vane wheel for an aeroengine, the vane wheel defining an axis, the vane having an airfoil presenting a leading edge and a trailing edge, the leading-edge curve describing the shape of the leading edge of the airfoil in a view perpendicular to the airfoil presenting at least one leading-edge undulation, said at least one leading-edge undulation extending over less than 30% of a length of the airfoil from the first end of the airfoil.

Leading edge profile of vanes

A field of turbomachine rotor blades, and in particular a turbomachine rotor blade including a blade root and a blade tip spaced apart by a blade height, together with at least one intermediate segment presenting a negative tangential slope, and a distal segment situated between the intermediate segment and the blade tip and presenting a positive tangential slope, wherein the distal segment extends over at most 30% of said blade height.
