Abstract: A combustor assembly for an automotive gas turbine engine includes a continuously ignited, pilot flame tube supported on a combustor dome immediately downstream of an inlet fuel nozzle and air swirler assembly. The pilot flame tube has an air swirler and fuel nozzle supported on an interior bulkhead and air is supplied upstream of the bulkhead and through a double-walled porous tube assembly for cooling wall portions of the flame tube exposed to the flame front within the combustor and wall portions thereof exposed to a pilot flame formed within the flame tube.
