Title
(EN) NACELLE ANTI-ICE VALVE UTILIZED AS COMPRESSOR STABILITY BLEED VALVE DURING STARTING
(FR) VANNE D'ANTIGIVRAGE DE NACELLE SERVANT DE VANNE DE PRÉLÈVEMENT DE STABILITÉ DE COMPRESSEUR PENDANT UN DÉMARRAGE
Abstract
(EN) A gas turbine engine has a compressor section received within an inner housing. An is an outer housing is spaced radially outwardly of the inner core housing. A nacelle has an anti-icing system which taps compressed air from the compressor section through an anti-ice valve and to the nacelle. The anti-ice valve is opened at startup of the gas turbine engine to assist compressor stability.
(FR) Selon la présente invention, un moteur de turbine à gaz possède une section compresseur accueillie dans un logement interne. Un logement externe est espacé de façon radiale vers l'extérieur du logement de cœur interne. Une nacelle possède un système d'antigivrage qui soutire de l'air comprimé de la section compresseur à travers une vanne d'antigivrage et en direction de la nacelle. La vanne d'antigivrage est ouverte au démarrage du moteur de turbine à gaz pour faciliter la stabilité du compresseur.
