Abstract
The invention concerns a combustion chamber () comprising a neck () downstream of the injection () of gases, and downstream of this neck a divergent section () whereof the outer face of the wall (), when in operation, is cooled by a cooling system using a cryogenic product and surrounding this outer face. This divergent section (), on the inner face () of its wall (), comprises a coating () acting as temperature compensator so that the temperature of the inner face () of the coating () is higher than the condensation temperature of the combustion gases on this inner face () under operating conditions, such that no condensation is formed on this inner face ().
