A combustion chamber (15) comprises an upstream ring structure (44), a downstream ring structure (54, 56) and a plurality of circumferentially arranged combustion chamber segments (58, 60). Each combustion chamber segment (58, 60) extends the full length of the combustion chamber (15). Each combustion chamber segment (58, 60) comprises a frame structure (75) and at least an inner wall (66) and the frame structure (75) and the inner wall (66) are integral. An upstream end of each combustion chamber segment (58, 60) is secured to the upstream ring structure (44) and a downstream end of each combustion chamber segment (58, 60) is mounted on the downstream ring structure (54, 56). The combustion chamber segments (58, 60) are manufactured by additive layer manufacture. The combustion chamber segments (58, 60) have a stiff frame structure (75) which carries the structural loads, the thermal loads, surge loads and flameout loads and the frame structure (75) distributes loads into adjacent components. |
