IMPELLER OF ROTOR OF GAS TURBINE ENGINE WITH DAMPENING OF VIBRATION OSCILLATIONS Russian patent published in 2015 - IPC F01D5/30 F01D5/26 

FIELD: machine building.

SUBSTANCE: impeller of rotor of gas turbine engine contains the rotor disk with ring groove, in which by means of the shanks the rotor blades, and, at least one lock device are secured. The impeller is equipped with at least one hole, made in the base of the disk groove, and rotor blades are interfaced with each other along the flange ends. The lock device contains lock and lock element with thread and smooth areas, at that the lock element is installed in hole by the smooth area. The lock is made in form of the wedge located in the thread area of the lock element by larger side along direction to the disk axis, and creates wedge joint between the adjacent shanks.

EFFECT: invention ensures minimum dimensions and weight of the rotor at required safety factor, increases endurance of gas turbine engine due to implementation of the dampening system of blades oscillation without use of the additional parts and elements.
