Abstract: A rotor vane for an aircraft turbine engine, the vane having an axis of rotation once it has been rigidly connected to a rotor and a stacking axis. The vane includes a blade extending between an internal platform and an external platform bearing at least one projecting lip. The external platform is configured to cooperate in a form-fitting manner with the complementary side edges of adjacent vanes. The rotor vane has wear-resistant covering of a lower side edge which extends over one wall of a substantially rectilinear first ridge of the platform and over one wall of a second ridge of the platform. The second ridge extends at least partially inside the lip and is inclined relative to the first ridge in a direction substantially parallel to a transverse axis of the lip.

Abstract: The invention relates to a rotor vane (10) for an aircraft turbine engine, said vane having an axis (A) of rotation once it has been rigidly connected to a rotor and a stacking axis (X). The vane comprises a blade (16) extending between an internal platform (19) and an external platform (20) bearing at least one projecting lip (31, 32), said blade having a lower surface (16a) and an upper surface (16b). The external platform comprises lower (22) and upper (21) side edges, located on the side of the lower (16a) and upper (16b) surfaces respectively and configured to cooperate in a form-fitting manner with the complementary side edges (21, 22) of adjacent vanes, each of said side edges having a wear-resistant covering (36).
