Cooling the upstream end plate of a high pressure turbine by means of a system of dual injectors at the end of the combustion chamber |
摘要 |
The invention relates to a device for ventilating a high pressure turbine rotor which comprises a turbine disk and an upstream end plate. A first circuit for cooling blades delivers a first air flow via main injectors and holes formed in the end plate. A second cooling circuit delivers a second air flow through a discharge baffle situated downstream from the compressor, a fraction of this second flow serving to cool the upstream top face of the end plate through a second baffle situated beneath the main injectors. A branch connection is provided between the first circuit and the enclosure situated downstream from the second baffle and it delivers a third flow which is set into pre-rotation by additional injector means formed in the form of inclined bores.
