Abstract

In order to provide a combustion chamber, in particular for a rocket engine, comprising a combustion area, an inner shell surrounding the combustion area, an outer shell surrounding the inner shell and coolant passages formed between the inner shell and the outer shell, the casing of which has an improved thermal stability and an increased mechanical bearing strength, it is suggested in accordance with the invention that the outer shell be formed from a fibrous ceramic material and the inner shell be formed from a fibrous ceramic material or from graphite.
