Title (EN) AIRCRAFT POWERPLANT
(FR) GROUPE MOTOPROPULSEUR D'AÉRONEF
Abstract:
(EN) A gas turbine engine system is disclosed which includes a core passage and a bypass passage which can be configured as a fan bypass duct or a third stream bypass duct. The core passage and bypass passage are routed to flow through a nozzle before exiting overboard an aircraft. The nozzle includes moveable members capable of changing a configuration of the nozzle. In one form the moveable members are capable of changing throat areas for portions of the nozzle that receive working fluid from the core passage and the bypass passage. The bypass passage can include a branch. In one form the branch can include a heat exchanger. The bypass passage can also provide cooling to one or more portions of the nozzle, such as cooling to a deck of the nozzle.
(FR) La présente invention concerne un système de moteur de turbine à gaz comprenant un passage central et un passage en contournement pouvant prendre la forme d'un conduit de contournement à ventilateur ou d'un troisième conduit de contournement de flux. Le passage central et le passage en contournement sont dirigés de façon à circuler à travers une tuyère avant de sortir à l'extérieur d'un aéronef. La tuyère comprend des éléments mobiles capables de modifier la configuration de la tuyère. Dans un mode de réalisation, les éléments mobiles sont capables de modifier les aires des vannes papillon des parties de tuyère recevant le fluide actif provenant du passage central et du passage en contournement. Le passage en contournement peut comprendre une dérivation. Dans un mode de réalisation, la dérivation peut comprendre un échangeur thermique. Le passage en contournement peut également servir à refroidir une ou plusieurs parties de la tuyère, par exemple le refroidissement du tablier de la tuyère.
