I designed this thing to improve the efficiency of axial part cooling fans.
Axial fans are good at moving high volumes of air at a low pressure.
One problem with a ducted axial fan though, is the big negative pressure vortex behind where the hub, or motor is. Filling that volume with a cone really smooths out the air flow inside the duct.
Another issue with axial fans is efficiency drops as back-pressure increase more rapidly than it does with radial fans. What happens is that the
