ABSTRACT:
A description is given of a damping arrangement for reducing resonant vibrations in a combustion chamber (1), with a combustion-chamber wall (2), which is of double-walled design and, with an outer wall-surface part (22) and an inner wall-surface part (21) facing the combustion chamber (1), gastightly encloses an intermediate space (3), into which cooling air can be fed for purposes of convective cooling of the combustion-chamber wall (2).The invention is distinguished by the fact that at least one third wall-surface part (4) is provided, which, with the outer wall-surface part (22), encloses a gastight volume (5), and that the gastight volume (5) is connected gastightly to the combustion chamber (1) by at least one connecting line (6).
