Abstract
A.DISPOSITIF POUR REDUIRE AU MINIMUM ET MAINTENIR CONSTANTES LES FENTES QUI, DANS LES TURBINES AXIALES, SE TROUVENT ENTRE LES EXTREMITES EXTERIEURES LIBRES DES AUBES MOBILES DE LA TURBINE, OU ENTRE UN BANDAGE EXTERIEUR DE CES AUBES, ET UN CARTER DE TURBINE ADJACENT, NOTAMMENT POUR DES TURBOMACHINES A GAZ. B.DISPOSITIF CARACTERISE EN CE QUE AU CARTER EXTERIEUR DE LA TURBINE OU A UN SUPPORT CORRESPONDANT 11 DES AUBES DIRECTRICES DE LA TURBINE EST SUSPENDU, DE FACON A POUVOIR SE DEFORMER ELASTIQUEMENT EN DIRECTION RADIALE, UN ELEMENT DE CONSTRUCTION ANNULAIRE 27 FORMANT MANCHON, QUI EST SOUMIS A L'ACTION D'AIR PROVENANT DE L'EXTREMITE DU COMPRESSEUR. C.L'INVENTION S'APPLIQUE NOTAMMENT AUX TURBINES A GAZ.
