FIELD: machine building.
SUBSTANCE: invention relates to the general field of aviation gas turbine engines, in particular to the field of attached shelves of fan blades of an aircraft gas turbine engine. Rotary assembly of aircraft gas turbine engine comprises fan disk with at least one tooth, and at least one flange installed on tooth of fan disc. Tooth of the fan disk contains a lug located in axial continuation of the specified tooth at the inlet, and the shelf contains at the level of its input end a retaining ring, into which the tooth blade of the fan disk should enter. Assembly additionally comprises an insert installed inside the locking ring with the possibility of the shelf blocking on the tooth of the fan disk tooth. Invention also relates to a gas turbine engine fan comprising such a unit, as well as to a method of mounting such a unit.
EFFECT: invention allows optimizing the characteristics of the fan and, in general, the gas turbine engine.
