CONTROL DEVICE OF ALIGNMENT OF SYNCHRONISING CONTROL RING OF ROTATING BLADES OF GAS TURBINE ENGINE, NUMBER OF BLADES OF COMPRESSOR STATOR, WHICH INCLUDES SUCH DEVICE, GAS TURBINE ENGINE INCLUDING SUCH DEVICE Russian patent published in 2010 - IPC F01D17/16 F04D29/56 F01D9/02 

FIELD: machine building.

SUBSTANCE: control device of alignment of control ring of rotating blades of gas turbine engine relative to its longitudinal axis, in which the control ring envelopes the annular surface aligned in the axis of gas turbine engine, includes many shoes intended for being engaged with the above annular surface. Each rotating blade is connected to control ring by means of the locking dog the first end of which is fixed on the control ring by means of trunnion installed radially on the above ring, and its other end is installed on rotating pin of the blade. Each shoe is fixed on shoe holder; at that, each shoe holder is fixed under the control ring by means of connecting systems intended for being assembled above the ring. Each shoe holder includes mainly the tubular part passing in longitudinal direction from control ring towards its inner space with possibility of installing an additional tubular part of shoe in it. Also device has the screw intended for being screwed into additional tubular part of shoe for controlling the radial position of the shoe. Other inventions of the group relate to the number of compressor stator blades and gas turbine engine, which include the above described control device of alignment of control ring of rotary blades.

EFFECT: improving the reliability of control device of ring alignment, simplifying its installation and removal.
