Abstract
A combustor dome may be formed by way of additive layer manufacturing. The combustor dome may further include a raised outer surface and a recessed outer surface on a hot side of the combustor dome. The recessed outer surfaces may be closer to the cold side than the raised outer surfaces. The combustor dome may include a shadow surface defined between the raised outer surface and recessed outer surface. The shadow surface may define a corresponding cooling outlet in fluid communication with an internal cooling channel defined inside of the combustor dome. The cooling outlet may release air from the internal cooling channel to the hot axial side of the combustor dome.
