IMPROVED GROUP OF HOLES OF COMBUSTION CHAMBER LININGS OF GAS TURBINE ENGINE WITH LOW DYNAMIC OF COMBUSTION AND EMISSIONS Russian patent published in 2016 - IPC F23R3/06 

FIELD: machine building.

SUBSTANCE: internal casing contains the internal wall element that contains a group of the first holes and a group of the second holes. The internal wall element encloses the combustion volume of the combustion chamber. The group of the first holes contains the first holes, through which fluid flows, and that are located in the first surface density. The group of the second holes contains the second holes, through which the fluid flows, and that are located in the second surface density. The first surface density differs from the second surface density. The external casing contains the external wall element that contains a group of additional first holes and a group of additional second holes. The external wall element of the external casing at least partially encloses the internal wall element of the internal casing such, that between the internal wall element and external wall element a clearance is ensured. The group of the additional first holes contains the additional first holes, through which the fluid flows, and that are located in the additional first surface density. The group of the additional second holes contains the additional second holes, through which fluid flows, and that are located in the additional second surface density. The additional first surface density differs from the additional second surface density.

EFFECT: creation of the combustion chamber with the reduced instability of burning and lesser emissions.
