Abstract
A turbine engine, including a final centrifugal compressor stage associated with a diffuser for supplying air to a combustion chamber, and a ventilation element for ventilating a high-pressure turbine wheel, is disclosed. The ventilation element includes an injection element for injecting air onto the wheel and a take-up element for taking up a flow for cooling the impeller of the compressor, where the take-up element has a labyrinth seal mounted at the outlet of the injection element, and the air outlet orifices are installed between the injection element and the labyrinth seal and leading upstream of the turbine wheel.
