Abstract

a. Entrée d'air de turbine à gaz. b. Elle comprend : un dispositif intérieur et un dispositif extérieur formant fourreaux délimitant un passage d'air de forme annulaire qui va en s'incurvant vers l'intérieur, par rapport à l'axe géométrique du moteur, d'un élément d'entrée jusqu'à l'entrée du compresseur- du moteur; une série d'étais creux dirigés radialement, dans la partie incurvée du passage d'air; un capteur en forme de V loge dans la partie incurvée du passage et qui recueille les substances à l'etat de particules dans la partie intérieure du flux d'air; des moyens servant à entretenir une dépression à l'intérieur des étais pour y aspirer les particules et un capteur servant à prélever les substances à l'état de particules dans la partie extérieure de ce flux d'air. c. Pour turbines à gaz fonctionnant dans une ambiance défavorable.
