FIELD: turbines or turbomachines.
SUBSTANCE: invention relates to movable blade (34) for a gas turbine engine comprising shank (41) configured to be inserted into receiving element (62) of rotor disc (38) for a gas turbine engine, shelf (48) carried by shank (41) , and blade blade (42) protruding from flange (48). Shelf (48) comprises upstream collar (50). According to invention, upstream collar (50) comprises tab (54) for engaging disc with locking cutout (64) so as to retain blade (34) in axial direction relative to disc (38), in accordance with longitudinal direction (XX) of receiving element (62).
EFFECT: easy installation and axial retention of the blade relative to the disk along the longitudinal direction, providing greater compactness of the blade, which reduces the weight of the blade and limits leakage.
