Abstract (en)
[origin: US2019128121A1] A low-pressure compressor for an axial-flow turbomachine, such as a jet engine, includes an annular row of vanes and a between-vanes passage with a connecting surface that links the pressure surface of a first vane to the suction surface of a second vane of the row. The connecting surface includes a main protuberance which includes a first elevation and a second elevation that are spaced apart from one another.
Abstract (fr)
L'invention concerne un compresseur basse-pression de turbomachine axiale, tel un turboréacteur. Le compresseur comprend une rangée annulaire d'aubes (26) et un passage inter-aubes (42) avec une surface de liaison (44) reliant la surface intrados (38) d'une première aube (26) à la surface extrados (40) d'une deuxième aube (26) de la rangée. La surface de liaison (44) comporte une protubérance principale (52) qui comprend une première bosse (54) et une deuxième bosse (58) écartées l'une de l'autre.
