Difference between forward and backward-swept axial fan blades ?
Difference between forward and backward-swept axial fan blades ?
(OP)
Hi,
I have been researching why most axial fan blades are forward swept like this picture:

while there are very few with backward swept blades:

One explanation I have found is that forward swept fans have less induced drag from tip vortex, because flow tends to travel span-wise towards root of blade. Is this true ?
