DEVICE USED FOR DIRECTING STRUCTURAL ELEMENT TO HOLE LOCATED IN WALL OF GAS-TURBINE ENGINE COMBUSTION CHAMBER, GAS-TURBINE ENGINE COMBUSTION CHAMBER AND GAS-TURBINE ENGINE CONTAINING ABOVE DEVICE Russian patent published in 2010 - IPC F23R3/60 

FIELD: engines and pumps.

SUBSTANCE: device used for directing the structural element to the hole drilled in the wall of gas-turbine engine combustion chamber includes a collar and sleeve coupling, which are coaxially located one inside the other. Collar is designed for coaxial structural element to be arranged inside it and includes annular protruding edge which is taken at an angle of 90° to inner annular groove of sleeve coupling provided with possibility of being attached to the edge of the hole in outer wall of combustion chamber. Collar and sleeve coupling form an annular cylindrical channel around the structural element, which has the outlet to the chamber. Device includes air circulation means made in the collar and/or sleeve coupling and uniformly distributed in a circumferential direction in order to provide the supply of outside air through cylindrical channel inside combustion chamber. Air circulation means include through holes drilled in annular protruding edge of the collar, uniformly distributed in circumferential direction of collar and connected to annular cylindrical channel.

EFFECT: increasing strength of the device and structural element.
