FIELD: machine building.
SUBSTANCE: group of inventions relates to radial wheels with forward bent blades for fans and compressors. Radial impeller comprises front 1 and rear 2 disks, installed between them forward bent blades 3 to make vane channels 9 with decreasing cross-section area at distance from inlet 5 to output 6 of radial impeller. Fan unit is installed in body 10 radial impeller and straightener, made in form of radial diffuser 12 with front and rear 13 rings, between which at outlet 15 may be installed blades 14 or aerodynamic ridges 16 adjoining rings 12 and 13.
EFFECT: technical result is upgraded static component of full pressure and efficiency.
