Abstract:
1. A damping arrangement for reducing resonant vibrations in a combustion chamber, the damping arrangement comprising: a double-walled combustion-chamber wall defining a combustion chamber and having an outer wall-surface part and an inner wall-surface part facing the combustion chamber, the outer wall-surface part and the inner wall-surface part gastightly enclosing an intermediate space into which cooling air can be fed for convective cooling of the combustion-chamber wall; at least one third wall-surface part which cooperates with the outer wall-surface part to enclose a gastight volume; at least one connecting line; wherein the gastight volume is connected gastightly to the combustion chamber by the at least one connecting line; and wherein the third wall-surface part is positioned on an opposite side of the outer wall-surface part from the combustion chamber and encloses the gastight volume with said outer wall-surface part.
