FIELD: machine engineering, namely designs of blades of axial blow blowers for cooling engines of motor vehicles. SUBSTANCE: blade includes running against convex end, running off concave end, root portion and upper edge. In root portion of blade running off end is restricted by face normal relative to fan axis. In the result blade with five angles is formed. EFFECT: enhanced efficiency due to lowered turbulence of air flow in zone of root portion, lowered lengthwise size of working part of blower. 1 dwg
