Apparatus for ventilating a turbine stator ring |
摘要 |
This ventilation apparatus uses gas under pressure diverted from a cooler area of the turbine that reaches a chamber and (8) successively passes through a cover (6) perforated with flow-restricting apertures (13), and then a wall (7) perforated with distribution apertures (12) before reaching a stator ring exposed to the heat that must be cooled, that economizes the ventilation gas due to the almost unperforated cover (6). This construction can be fitted to high pressure turbine stator rings. The cover and the wall form a single unit and the apertures restricting the flow are in the form of nozzles opening into the volume formed by the unit.
