Abstract
A combustion chamber wall structure for a high performance propulsion plant or a wall structure for a nozzle of flying bodies has an outer pressure jacket and an inner wall member provided with a multitude of cooling channels. In operation the inner wall is in contact with hot gases. An intermediate layer made of a material having shape memory characteristics and/or superelastic characteristics is arranged between the inner wall member and the outer pressure jacket.
