FIELD: engines and pumps.
SUBSTANCE: method is implemented in the ring of drive of stator rotary blades of gas-turbine engine with radial holes made in it, in which there installed are collar bushings contacting with the surface of the drive ring, which are connected to rotary blades by means of levers one end of each of which is installed in open rectangular slot made on surface of the drive ring and rigidly attached to the pin contacting with inner surface of bushing, and the other one is rigidly attached to rotary blade; at that, it is equipped with locking members to restrict radial movement of bushings, collars arranged opposite them; at that, slots are made on inner surface of drive ring; levers are installed on the side of the latter; at that, drive ring is equipped with shields; levers are arranged in slots in the gap between inner surface of ring and shields, bushing collars and locking members are arranged on the side of external ring surface.
EFFECT: preventing detachment of levers from the drive ring at any deformation of levers.
