Abstract: A combustion chamber includes at least one annular wall which includes at least one box like structure and each box like structure includes an inner wall, outer wall, upstream end wall and downstream end wall. The inner wall is spaced radially from the outer wall and the outer wall has a plurality of apertures for the supply of coolant into the box like structure. The inner wall, the outer wall, the upstream end wall and the downstream end wall are integral. The upstream end of the annular wall has features to secure the annular wall to an upstream ring structure and a downstream end of the annular wall has features to mount the annular wall on a downstream ring structure. The inner wall has at least one slot extending through the full thickness of the inner wall to accommodate differential thermal expansion between the inner wall and the outer wall.

Abstract: A combustion chamber comprises an upstream ring structure, a downstream ring structure and a plurality of circumferentially arranged combustion chamber segments. Each combustion chamber segment extends the full length of the combustion chamber. Each combustion chamber segment comprises a frame structure and at least an inner wall and the frame structure and the inner wall are integral. An upstream end of each combustion chamber segment is secured to the upstream ring structure and a downstream end of each combustion chamber segment is mounted on the downstream ring structure. The combustion chamber segments are manufactured by additive layer manufacture. The combustion chamber segments have a stiff frame structure which carries the structural loads, the thermal loads, surge loads and flameout loads and the frame structure distributes loads into adjacent components.
