RECTIFIER OF GAS-TURBINE ENGINE WITH VANES OF IMPROVED PROFILE Russian patent published in 2017 - IPC F01D5/14 F01D9/04 F04D29/54 

FIELD: engines and pumps.

SUBSTANCE: rectifier of a gas-turbine engine comprising a plurality of vanes disposed around a ring with a center on the axis of the gas-turbine engine. Each vane has a leading edge and extends between the end of the leg and the end of the head. The leading edge at the end of the leg of each vane is biased towards the inlet in the direction of the axis of the gas-turbine engine relative to the leading edge at the end of the head. The displacement of the leading edge between its two ends exceeds by 10% the blade height measured in the direction of the axis of the gas-turbine engine. The tangential set curve, formed by the position in the tangential direction to the ring of the gravity centers of the successive vane sections along the vane height, is a curve which is constantly increasing to the back of the vane. The gas-turbine engine is also presented.

EFFECT: invention allows to improve the characteristics of the rectifier vane and to reduce the air separation from the vane head.
