SYSTEM OF ROTATING BLADES STAGES CONTROL OF HIGH PRESSURE COMPRESSOR STATOR Russian patent published in 2013 - IPC F01D17/16 F04D29/56 

FIELD: machine building.

SUBSTANCE: control system of stator rotating blade stages includes executing mechanism, synchronising rings, rods, levers attached on journals of rotating blades and additional levers mounted on stator housing. One of additional levers is three-shouldered and, at least, the other one - two-shouldered. Three-shouldered lever is connected by the first shoulder to synchronising ring hinged to levers fixed on journals of rotating blades of guiding apparatus of the first stage. Three-shouldered lever is connected by the second shoulder to synchronising ring hinged to levers fixed on journals of rotating blades of guiding apparatus of the second stage. Three-shouldered lever is connected by the third shoulder to executing mechanism. Two-shouldered lever is connected to executing mechanism by the first shoulder and by the second shoulder - to the synchronising ring hinged to levers fixed on journals of rotating blades of guiding apparatus of the third or one of the following stages. Profile backs of rotating blades of the first stage are arranged by gas flow downstream and backs of rotating blades of the second and, at least, the following stage are arranged against gas flow.

EFFECT: invention allows increasing quick response of rotating blade stages control system.
