Title (EN) COAXIAL TURBOMACHINE
(FR) TURBO-MACHINE COAXIALE
Abstract:
(EN) A centrifugal compressor (10/110) or a centripetal turbine (76) having coaxially aligned, relatively rotatable rotors (12, 112, 212/14, 114, 214) mounting a plurality of blades (30, 32, 34, 36, 38/130/230) having variable radial extension from a central axis (15). The blades closer to the center of rotation of the rotors are operated at high speeds so to maximize their gas treating effect while rotating the larger diameter blades (40, 42, 44/132, 232) at lower speeds commensurate with their stress capabilities.
(FR) Compresseur centrifuge (10/110) ou turbine centripète (76) possédant des rotors alignés coaxialement et rotatifs entre eux (12, 112, 212/14, 114, 214) pourvus d"une pluralité de pales (30, 32, 34, 36, 38/130/230) possédant une extension radiale variable depuis un axe central (15). Les pales les plus proches du centre de rotation des rotors travaillent à des vitesses élevées de manière à porter au maximum leur effet de traitement de gaz tout en faisant tourner les pales de plus grand diamètre (40, 42, 44/132, 232) à des vitesses plus faibles adaptées à leur caractéristique de résistance aux efforts.
