Turbomachine with annular combustion chamber

摘要

The turbomachine has an annular chamber base (28) crossed by a fuel injection unit (42) and fixed to internal and external cases (14, 18) by respective internal and external walls (24, 26). An annular combustion chamber (46) has an upstream end connected to one of the cases by elastically deformable external and internal hinge plates (48, 49). Each plate is formed of bend spring plate extending circumferentially and distributed around the chamber. The plates are fixed on one of the cases by bolting and radially supported on the chamber base.
