Abstract
In order to cool the annular upstream wall of a gas turbine engine combustion chamber and thereby to prevent the deposition of carbon particles, the wall is formed of upstream and downstream portions which between them define a chamber arranged to receive a flow of cooling air. The downstream portion has a central opening for an airspray fuel burner and on each side of the opening the downstream portion has a pair of facets each facet having apertures for the throughflow of cooling air over the face of the downstream portion.
