Abstract (en)
[origin: EP1367221A1] The ventilation system for a turbine high-pressure rotor situated after a combustion chamber and having a forward turbine (3) flange (5) has a first cooling circuit delivering an air flow (C1) through main injectors (15) and apertures (11) in the flange. A second cooling circuit delivers a cooling air flow through a discharge labyrinth situated after the compressor, and a portion (C2c) of this second flow serves to cool the upper forward flange face through a second labyrinth situated beneath the main injectors. There is a branch between the first circuit and the cavity (23) located after the second labyrinth to deliver a third pre-rotated air flow through additional injectors (30) in the form of inclined channels.
