GAS TURBINE ENGINE HAVING STATOR STAGE OF BLADES WITH ADJUSTABLE SETTING ANGLE WITH INDEPENDENT CONTROL Russian patent published in 2015 - IPC F01D17/16 F04D29/56 F01D9/02 

FIELD: engines and pumps.

SUBSTANCE: gas turbine engine includes housing with a stator stage having blades with an adjustable setting angle, which are controlled by a drive ring coaxially enveloping the above housing. Movement of the ring is restricted by rotation only about the axis of the above housing and connected with knee levers to blades with an adjustable setting angle. The drive ring is connected to an adjacent individual drive unit in the form of a power drive and containing two sections forming a cylinder and a stock. The stock is hinged to the ring, and the cylinder is hinged to the above housing; with that, the hinge between the cylinder and the housing is located near the end of the cylinder, out of which the stock comes.

EFFECT: invention allows reducing overall dimensions and weight of a control system of a setting angle of stator blades.
