摘要： A turbomachinery engine includes a fan assembly, a low-pressure turbine, and a gearbox. The fan assembly includes a plurality of fan blades. The low-pressure turbine includes 3-5 rotating stages. The low-pressure turbine includes an area ratio equal to the annular exit area of an aft-most rotating stage of the low-pressure turbine divided by the annular exit area of a forward-most rotating stage of the low-pressure turbine. In some instances, the area ratio is within a range of 2.0-6.5. Additionally (or alternatively) the low-pressure turbine includes an area-EGT ratio within a range of 1.3-1.6.

摘要： L'invention concerne un ensemble pour une turbomachine d'aéronef, comprenant un réducteur de vitesse (4) comportant un pignon d'entrée (40) relié à un arbre de puissance (2) de la turbomachine et un pignon de sortie (41) relié à un arbre d'hélice (3) de la turbomachine.
Selon l'invention, l'ensemble comprend deux machines électriques (60) qui sont chacune configurée de manière à fournir de la puissance électrique à l'arbre d'hélice ou à prélever de la puissance mécanique sur l'arbre d'hélice, chaque machine électrique comprenant un rotor (61) et un stator (62), le stator étant destiné à être relié à un carter de la turbomachine, et en ce que le réducteur de vitesse comprend deux lignes intermédiaires de transmission (55) sensiblement parallèles et configurées pour transmettre le couple du pignon d'entrée (40) au pignon de sortie (41), chaque rotor (61) étant entraîné en rotation respectivement par un pignon d'une ligne intermédiaire (55).-

摘要： An aircraft assembly includes a geartrain (72) with a first gear system (94) and a second gear system (96). The first gear system (94) includes a first sun gear (98), a first ring gear (100), a plurality of first intermediate gears (102) and a first carrier (104). The first sun gear (98) and the first ring gear (100) are each rotatable about an axis (28,40,106). The first intermediate gears (102) are between and meshed with the first sun gear (98) and the first ring gear (100). Each of the first intermediate gears (102) is rotatably mounted to the first carrier (104). The second gear system (96) is interconnected with the first gear system (94). The second gear system (96) includes a second sun gear (108), a second ring gear (110), a plurality of second intermediate gears (112) and a second carrier (114). The second intermediate gears (112) are between and meshed with the second sun gear (108) and the second ring gear (110). Each of the second intermediate gears (112) is rotatably mounted to the second carrier (114).
