Claims (10)

  1. Compresseur centrifuge axial multi-étages incorporé dans, ou destiné à un turbomoteur à combustion et comportant un rotor cylindrique (12) supportant des aubes de compresseur (11), un stator segmenté définissant un carter intérieur segmenté (22) et comportant des rangées d'aubes de stator (30) espacées axialement, ledit carter intérieur étant monté sur un carter extérieur (20), caractérisé en ce que ce carter extérieur se compose d'une section fendue axialement et d'une section monobloc (34), cette dernière étant destinée aux étages finaux du compresseur, une partie correspondante du carter intérieur (22) étant suspendue à la partie de carter monobloc (34) de manière, une fois montée, à être retenue radialement tout en permettant son déplacement axial et sa dilatation thermique sur la circonférence.
  2. Compresseur selon la revendication 1, caractérisé en ce que ladite section du carter intérieur segmenté comporte une enveloppe extérieure (104) se prolongeant axialement et qu'au moins une partie des trois rangées d'aubes de stator (30) est fixée solidairement à chaque segment de ladite enveloppe extérieure de sorte que les segments une fois montés bout-à-bout sur la circonférence, forment un anneau complet.
  3. Compresseur selon la revendication 1 ou 2, caractérisé en ce que ladite section de carter intérieur est suspendue à la section de carter monobloc (34) par des moyens incluant au moins un crochet (126) prévu sur le carter intérieur segmenté, ce crochet pénétrant axialement dans un élément support (120) prévu sur le carter extérieur (34).
  4. Compresseur selon la revendication 3, caractérisé en ce que le support (120) comporte une rainure destinée à recevoir axialement le crochet (126), ainsi que des oreilles (127) qui s'engagent de chaque côté du crochet (126) pour empêcher le carter intérieur de tourner autour de l'axe du compresseur.
  5. Compresseur selon l'une quelconque des revendications précédentes, caractérisé en ce qu'il comporte également une bague entretoise (50) disposée entre le carter extérieur et le carter intérieur.
  6. Compresseur selon la revendication 5, caractérisé en ce que ladite bague est vissée par un filetage sur le carter intérieur et reliée au carter extérieur par un boulon (62) qui se visse dans le taraudage de la bague entretoise.
  7. Turbomoteur à combustion comprenant un compresseur selon l'une quelconque des revendications précédentes.
  8. Méthode d'assemblage de la partie compression d'un compresseur multi-étages de turbomoteur à combustion comprenant un rotor cylindrique (12) supportant les aubes de compresseur (18) et plusieurs stators segmentés espacés axialement définissant un carter intérieur (22) dont plusieurs sont supportés par un carter extérieur fendu axialement, caractérisée en ce qu'elle inclut les opérations de :
       montage du rotor cylindrique et du stator,
       montage d'un dispositif support tubulaire de forme allongée (140) sur une bride (42) du moteur sur laquelle sera finalement monté un carter extérieur monobloc,
       montage du carter extérieur monobloc (34) sur un support coulissant (146) monté sur ledit dispositif support tubulaire,
       fixation sur le carter extérieur monobloc d'un mécanisme porteur (120) permettant de monter le stator segmenté sur ledit carter extérieur monobloc, alignement dudit mécanisme porteur (120) de manière à ce qu'il rentre dans une formation complémentaire consistant en une structure porteuse (126) formée sur le carter intérieur,
       fixation du carter extérieur monobloc (34) à la bride (42) du moteur et retrait du dispositif support tubulaire de forme allongée (140), et
       fixation du carter extérieur tendu axialement au carter extérieur monobloc.
  9. Méthode selon la revendication 8, caractérisée en ce que ladite formation est une rainure.
  10. Méthode selon la revendication 8 ou 9, caractérisée en ce qu'elle inclut l'opération consistant à monter une bague entretoise creuse (50) sur le carter intérieur, à aligner une ouverture pratiquée dans le carter extérieur avec cette bague et à fixer un boulon (62) passant par l'ouverture de ladite bague entretoise.
