Definitions
- the air sampling can be carried out on the intrados and / or extrados of the blades, and the blowing on the intrados and / or extrados vanes;
- the passages have a central axis inclined relative to a normal to the face on which it opens, with an angle substantially between 0 and ⁇ 90 °, preferably an angle close to 90 ° for the upstream passages and close to 0 ° for downstream passages;
- a longitudinal groove 62 now appears.
- This groove opens on the trailing edge 6f, without opening on the leading edge 6a.
- This groove is made by machining the metal alloy material of the sidewall 6p of each vane 60, forming longitudinal walls 65, substantially parallel to the intrados face 6i and extrados 6e, and bottom 66 parallel to the sidewalls 6p.
- the re-energizing of the incoming air flows then makes it possible to stabilize these flows and to prevent their detachment or possibly to pick them up again if the detachment is initiated. Suction at the trailing edge, or in areas close to the trailing edge, also makes it possible to attenuate - or even eliminate - the potentially unstuck areas.
- Figures 5a to 5c relate to vanes 60 of grooves 62a to 62c respectively of constant width "e” and leading to the trailing edge 6f (groove 62a, diagram 5a), or of width "e” linearly variable as a function of the mean curvilinear abscissa Sm of the blade 60 (grooves 62b and 62c, diagrams 5b and 5c).
- the groove may be opening (grooves 62a and 62c, diagrams 5a and 5c) or non-opening (groove 62b, diagram 5b) on the trailing edge 6f.
- the trailing edge 6f When the groove is opening, the trailing edge 6f then has flanges 67 shaped to optimize the suction of air.
- FIG. 6a illustrates a front view of a third example of a diffuser 60 according to the invention.
- the air intake - always performed in trailing edge region 6f of the diffuser 6 (arrow F2) is achieved by suction through an opening 70 made radially in the flange 61.
- the cavities and slots are not necessarily cylindrical or partially cylindrical but can vary in section: prismatic, oblong, etc.
- the transit housing can be formed in the housing or in the hub of the diffuser.
