| 摘要 |
<p>The invention concerns a gas turbine stator comprising: at least first injection means (1) providing a passage for main cooling air stream into a pressurized chamber (16), means for evacuating discharge air coming from an internal labyrinth gland (13) of a first cavity (9) towards a lower-pressure second cavity (10), second injection means for evacuating the air contained in said second cavity (9) towards a main duct. The inventive stator is characterized in that it further comprises third injection means designed to generate an overpressure close to the internal labyrinth gland (13a, 13b) in said pressurized chamber (16).</p> |
