Abstract (en)

[origin: EP1881179A2] The system has an L-sectioned annular downstream end-piece (28) connected to an annular diffuser (12) and extending towards downstream to an air injection unit (42) for ventilating a turbine. An annular convection metal sheet (100) is arranged radially between a tapered shaped annular combustion chamber (14) and the end-piece. The sheet extends axially from the diffuser to the unit along a radial internal wall (48) of the chamber to delimit an annular internal air flowing stream (90), with the wall. The stream supplies air through holes in the wall of the chamber and the unit.
