Definitions
- the module comprises a fixed shroud that receives in an opening a fan rotating about a main axis.
- the opening may be circular.
- the opening is circumvented by a peripheral wall extending in the downstream direction, relative to the main air flow, beyond the fan toward a corner edge where the wall reorients radially and inwardly to extend toward a circular downstream edge.
- the reorientation of the peripheral wall may be done smoothly, for instance in a curve, or abruptly with an angle.
- the downstream portion of the peripheral wall forms an annular channel opening in the upstream direction.
- the channel forms a continuous space to the gap that is between the tips of the blades of the fan and the peripheral wall.
- the gap is continuous, non-divided and non-partitioned.
- the downstream portion 42 forms a quadrant 44 with radius R substantially equal to the width of the gap G, the centre of said quadrant 44 being located upstream the corner 34.
- the circular portion formed by the quadrant 44 is followed by a short straight portion so that, the downstream edge 34 faces the downstream edge of the ring or of the blade, and forms into the gap G a 360°opening 48 of width W.
