COMBUSTION CHAMBER OF GAS TURBINE ENGINE Russian patent published in 2006 - IPC F23R3/60 

FIELD: combustion chambers.

SUBSTANCE: combustion chamber of gas turbine engine has inner and outer cases, flame tubes, sprayers, pins of suspension of flame tubes and gas collector provided with ring-shaped flanges into which flanges the corresponding ring-shaped flanges of flame tubes insert in disposed at their last sections. Gas collector is combined of individual gas-collecting jets, which have sheet case, ring-shaped flange and profiled frame-typed flange which flanges are connected together by weld insertions at the area of their ring-shaped flanges as well as by means of floating ring. Protrusions enter ring-shaped recess of the floating ring. Protrusions are disposed at lower part of profiled frame-typed flange. Gas collector also has weld ring-shaped adapter, which has end to enter grooves at top part of profiled frame-typed flanges. Flame tunes have head provided with swirler and a number of sections. The last section in the row has ring-shaped flange. Any jet has flange fixed to corresponding lug of outer case. Cylindrical part of the jet enters axial hole of swirler of flame tube to provide its fixation at radial and circumferential directions. Any pin of suspension of flame tube has its flange fixed onto corresponding lug of outer case and has its cylindrical end to enter hole of hinge disposed in nest of bushing. The bushing is disposed onto head of flame tube to provide its fixation at axial direction.

EFFECT: improved efficiency of operation.
