A turbomachine vane damper constructed so as to be housed between the lower face of the platforms of two adjacent turbomachine vanes and the rim of the rotor disk on which the vanes are mounted is disclosed. The damper includes a weight, a bearing plate and a spring. The spring connects the weight to the bearing plate.

A turbine stator for an aircraft turbine engine is disclosed. The turbine stator includes a stator wall supporting a high pressure air injector fixed on the downstream side, and an annular abradable element support. The lower radial end of the element support is fixed to the high pressure air injector and the upper radial end of the element support is fixed to the stator wall, such that they jointly delimit a cavity under pressure. The turbine stator also includes at least one vibration damping device located in the cavity under pressure. The vibration damping device is in contact with each of the two elements taken among the stator wall and the annular support.

The rotor disk carries an axial retention plate facing slots having blade roots received therein, the disk and the plate are shaped so as to define outer circumferential interlock and inner circumferential interlock.

System for retaining blades in a rotor

A fan rotor is provided. Each blade of the fan rotor is held by a bolt. Each blade includes a blade root engaged in a groove of the rim and held by a bolt. The bolt includes a concave plate with its curve directed upstream.

A method of calibrating the mass of components intended to be mounted at the periphery of a rotor, the method consisting, for each of the components, in removing by machining a volume of material in a region of the component situated on one of its axes of inertia in order to bring the mass of the component to a predetermined value.
