Abstract
The fan comprises a hub containing a crown of radial blades, each with an angle varying along the radial coordinates, according to a non-monotonous function with at least two procedural inversions. The fan features an improved efficiency, in particular at low velocity rotation, and a considerably reduced noise level.
