    摘要: The invention relates to a mobile vane (34) for a turbine engine, comprising a root (41) designed to be inserted into a receiving element (62) of a rotor disk (38) for a turbine engine, a platform (48) carried by the root (41), and a blade (42) extending from the platform (48). The platform (48) comprises an upstream edge (50). According to the invention, the upstream edge (50) comprises a lug (54) for engaging in a locking notch (64) of the disk in such a way as to hold the vane (34) axially in relation to the disk (38), according to the longitudinal direction (XX) of the receiving element (62).
