Title (EN) GAS TURBINE ENGINE FOR LONG RANGE AIRCRAFT
(FR) MOTEUR À TURBINE À GAZ POUR AVION DE LONGUE PORTÉE
Abstract: front page image
(EN)A gas turbine engine comprises a fan for delivering air into a bypass duct as bypass flow, into a core housing as core flow, with the core housing containing an upstream compressor rotor and a downstream compressor rotor. An overall pressure ratio is defined across the upstream and downstream compressor rotors. A bypass ratio is defined as a volume of air delivered as bypass flow compared to a volume of air delivered into the core housing. The overall pressure ratio is greater than or equal to about 45.0, and the bypass ratio is greater than or equal to about 11.0.
(FR)Moteur à turbine à gaz comprenant une soufflante destinée à apporter l'air dans un conduit de dérivation en tant que flux de dérivation, dans un logement central en tant que flux central, le logement central contenant un rotor de compresseur amont et un rotor de compresseur aval. Un rapport de pression global est défini sur les rotors de compresseur amont et aval. Un rapport de dérivation est défini en tant que volume d'air délivré en tant que flux de dérivation par rapport à un volume d'air délivré dans le logement central. Le rapport de pression global est supérieur ou égal à environ 45,0, et le rapport de dérivation est supérieur ou égal à environ 11,0.
