Abstract

A gas turbine combustion chamber is provided. The gas turbine includes a combustion chamber interior and a combustion chamber wall which has a substantially rotationally symmetrical cross-section, wherein on the side of the combustion chamber wall facing away from the combustion chamber interior there is arranged over the entire cross-sectional circumference of the combustion chamber wall a corrugated component which, in combination with the combustion chamber wall, embodies a plurality of separate resonance chambers and wherein openings are incorporated in the combustion chamber wall in such a way that a fluidic connection is established in each case between the combustion chamber interior and one of the resonance chambers and wherein the corrugated component has two locking rings which are connected to the combustion chamber wall in order to seal off the resonance chambers.
