Abstract
An improved combustor bulkhead 70 for a gas turbine engine 10 includes a plurality of holes 72 and baffles 90 which directs cooling air radially inward around a fuel injector to set up and shape a toroidal recirculation zone 114 surrounding the fuel injector vortex 116 and suppress smoke and carbon formation in the combustion chamber. Various construction details are described to provide an aerodynamically superior bulkhead design.
