GAS-TURBINE ENGINE VANE WITH PROFILE PROVIDING IMPROVED AERODYNAMIC AND MECHANICAL PROPERTIES Russian patent published in 2017 - IPC F04D29/38 F01D5/14 F01D9/02 

FIELD: engines and pumps.

SUBSTANCE: gas turbine engine vane having a plurality of vane sections packed along the radial axis (Z-Z). Each vane section is located along the longitudinal axis (X-X) between the leading edge and the trailing edge and along the tangential axis (Y-Y) between the side of the trough and the back side. The vane sections are distributed according to the rules of longitudinal Xg and tangential Yg distribution, determining the position of their respective centres of gravity with the ratio of the mentioned longitudinal (X-X) and tangential (Y-Y) axes over the vane height extending from the vane leg to the tip of the vane. Each of the mentioned rules of longitudinal Xg and tangential Yg distribution has a change in the direction of inclination between 90 and 100% of the vane height.

EFFECT: increased efficiency in the upper part of the vane, improved mechanical characteristics due to reduction of static voltages, without affecting the dynamic characteristics.
