Title (EN) ADJUSTABLE BLADE OUTER AIR SEAL APPARATUS
(FR) APPAREIL D'ÉTANCHÉITÉ À L'AIR EXTERNE À LAMES RÉGLABLES
Abstract:
(EN) An adjustable blade outer air seal apparatus includes a case structure that extends circumferentially, a support ring structure mounted radially inwards of the case structure and at least one blade outer air seal segment radially adjustably mounted relative to the support ring structure.
(FR) L'invention porte sur un appareil d'étanchéité à l'air externe, à lames réglables, qui comprend une structure d'enveloppe qui s'étend de façon périphérique, une structure de bague de support montée radialement à l'intérieur de la structure d'enceinte et au moins un segment d'étanchéité à l'air externe, à lames, monté de façon à pouvoir être réglé radialement par rapport à la structure de bague de support.
