Abstract
A gas turbine engine annular combustor having a bulkhead at its upstream which is thermally protected by an annular array of heat shields. Each heat shield is provided with integral flanges which space apart the heat shields and bulkhead to define chambers therebetween. Apertures in the bulkhead direct cooling air into the chambers at positions adjacent the outer peripheries of the heat shields. The cooling air flows generally inwards within each chamber before being exhausted therefrom.
