AXIAL FAN, PARTICULARLY FOR MOTOR VEHICLES FOR AGRICULTURAL USE

The angle of curvature ( alpha r) of the median line (M) of each blade (3) in axial projection is nil at the hub (2) and for about one third of the radial extension (Ro - Ri) of the blade from the hub (2). The blade angle ( beta ) of each blade (3) is substantially constant along the blade and the c...

Summary:The angle of curvature ( alpha r) of the median line (M) of each blade (3) in axial projection is nil at the hub (2) and for about one third of the radial extension (Ro - Ri) of the blade from the hub (2). The blade angle ( beta ) of each blade (3) is substantially constant along the blade and the chord (d) between the leading edge (A) and the trailing edge (B) of each blade (3) is substantially constant along the blade (3) between the hub (2) and the outer ring (4).
