Abstract

La turbine de turbomachine à gaz s’étend autour d’un axe principal et comprend :- un stator,- un rotor comprenant une roue d’aubes, et- un circuit de ventilation. Le circuit de ventilation comprend :- au moins une centrifugeuse (30) agencée pour mettre de l'air en rotation et s’étendant le long d’un axe principal distant de l’axe principal de la turbine,- des injecteurs situés en aval de la centrifugeuse par référence à la direction d’un flux d’air dans le circuit de ventilation en fonctionnement et en amont d'une cavité interne qui débouche sur un disque du rotor, et- des ouvertures (46) agencées pour évacuer hors du circuit de ventilation des particules provenant de la centrifugeuse de sorte que les particules ne soient pas communiquées aux injecteurs. Figure pour l’abrégé : Fig. 3
