GAS TURBINE ENGINE TURBINE RING SECTOR, TURBINE RING, TURBINE CONTAINING SUCH RING, AND GAS TURBINE ENGINE CONTAINING SUCH TURBINE Russian patent published in 2009 - IPC F01D11/24 

FIELD: engines and pumps.

SUBSTANCE: turbine ring sector includes a wall restricting aerodynamic circuit in which gases move from inlet to outlet, and a perforated plate located opposite to aerodynamic circuit relative to the wall. Perforated plate consists of bottom and side walls. Distance between ring sector wall and perforated plate bottom restricts the gap varying in axial direction from inlet to outlet; at that, value of the gap located at the inlet is less than value of the gap located at the outlet. Other inventions of the group refer to turbine ring, turbine and gas turbine engine, each of which includes the above ring sector.

EFFECT: inventions allow decreasing deformations of ring sector owing to providing its uniform temperature.
