Definitions
- the invention relates to an axial compressor according to the preamble of claim 1.
- Axial compressors are well known. It refers to
- Vane rows provided to the fluid to be compressed on its way to the axially subsequent blade stage in an optimal
- a stationary vane arrangement or cascade is provided in order to change the fluid caused by the rotor swirl flow of the fluid in a substantially axial
- the invention is based on the recognition that aerodynamically optimized profiles of a multi-stage vane cascade behind the
- Vane stage is arranged offset in the circumferential direction, such that caused by the vanes of the preceding stage vortex flags each flow between adjacent guide vanes of the subsequent vane stage.
- the invention is based on the general idea of ensuring, in the case of stator vane stages arranged axially one behind the other, an as swirl-free as possible inflow in the downstream vanes.
- the swirl vanes have a smaller distance from the convexly curved side of the one adjacent guide vane of the subsequent vane stage than from the concavely curved side of the other adjacent vane.
- the housing of the axial compressor in a basically known manner from in
- Context is advantageously provided to arrange a split inner wall segment at a parting plane between adjacent shell parts of the housing, in such a way that the parting plane between the segment parts coincides with the parting plane between the shell parts of the housing.
- Fig. 1 is a schematic axial section of a conventional
- Axial compressor with an outlet-side vane cascade which consists of so-called super-vanes,
- Fig. 2 is a schematic axial section of an axial compressor with
- Vane cascade a partial sectional view of a conventional two-stage vane cascade, wherein all blade profiles are shown relative to a rolled-up inner wall of the compressor housing
- Fig. 4 is a corresponding to FIG. 3 representation of an inventive
- Compressor housing in the area of the output side
- a conventional axial compressor is shown. This has in a known manner a housing 1 with a rotor axis 2 to a substantially rotationally symmetrical inner wall 3.
- the housing 1 encloses a rotor 4, which is axially between an input 5 for a to be compressed
- Flow medium and an output 5 ' which usually leads to a combustion chamber, is arranged.
- rotor-fixed blades 6 are arranged in a known manner, in each case in the circumferential direction of the rotor extended blade rows or blade stages. Between axially adjacent blade stages each fixed to the housing vanes 7 are arranged, in each case in
- Circumferential direction of the housing inner wall 3 extended Leitschaufel Researchn or - stages.
- Axial behind the rotor blade stage of the rotor 4 is a single-stage
- Leitschaufelkaskade 8 two-stage with "normal" vanes 10 and 1 1 is constructed, which have a relatively little curved profile.
- Figs. 3 and 4 show the differences of the invention over previous designs.
- Fig. 3 the relative positions of the vanes 10 and 1 1 of a two-stage conventional vane cascade are shown.
- the distances Ui and U2 have the same dimensions, so that it can be ensured by appropriate offset of the guide vanes 1 1 of the subsequent vane stage in the circumferential direction, that the vortex lugs 13 each between circumferentially adjacent vanes 1 1 pass.
- each lower vanes 1 1 are passed.
- a construction according to FIG. 5 is preferably provided.
- the compressor housing is composed of shell parts, which are placed against each other, for example, at a parting plane 14.
- the guide vanes 10 and 1 1 mounted in a conventional manner, for example, the feet ch 1 5 and 16 of the vanes 10 and 1 1 with molded-on anchors in
- Circumferential direction are inserted into a formed in the inside of the respective shell part channel.
- an inner wall segment is arranged in each case 1 7 or 1 8, which is dimensioned such that between the leading edges of the vanes 1 0 and 1 1, the evident from Fig. 4 radians Ui and U 2 , which have the same dimensions, are present.
- each segmented wall segments with the segment parts 1 7 'and 1 7 "or 1 8' and 18" provided, wherein the respective segment parts 1 7 'and 1 7 "or 1 8' and 1 8" so be positioned so that its parting plane coincides with the parting plane 14 of the housing shell parts.
- FIGS. 1 to 5 are also one or more of the rotor side
- Blades 6 of the last blade stage shown schematically in profile, where R denotes the direction of rotation of the rotor 4.

Abstract
L'invention concerne un compresseur axial comprenant une grille d'aube directrice à deux étages (8) sur l'extrémité côté sortie (5) du rotor (4). Les aubes directrices (11) du second étage de la grille sont décalées dans la direction périphérique par rapport aux aubes directrices (10) du premier étage, de telle manière que les traînées tourbillonnantes provoquées par les aubes directrices (10) du premier étage ne peuvent agir sur les aubes directrices (11) du second étage.
