Abstract: The present relates to combustor apparatus for a gas turbine engine comprising a bulkhead (34) an inner support ring (70) and an outer support ring (84) at end upstream end thereof. The bulkhead (34) has an inner surface (40), when in use is provided on an internal surface of a combustor (16) and exposed to combustion products and an outer surface (41) provided on an external surface of the combustor when in use; an inner mating feature to cooperate with the inner support ring (70); and an outer mating feature to cooperate with the outer support ring (84). In use, the inner and outer mating features prevent axial motion of the bulkhead relative to the inner (70) and outer (84) support rings.

Abstract: Disclosed is an apparatus for the additive manufacture of a component comprising a substantially annular bed for supporting the component, a powder depositor, an energy beam source for emitting a beam of energy towards a beam target location, and control means for adjusting the beam target location. The apparatus is configured to provide rotation of the beam target location and/or the powder depositor relative to the bed, the relative rotation being about a rotational axis. Also disclosed are a method for additive manufacture, a gas turbine engine, and an aircraft.
