You guys said this was bad - that having more distance between tip & duct leads to more turbulence losses.
Their fans look thicker and heavier, different than PJ-2 fan-blade pictures shown by Malish.
Blades look wider. Even hub of fan looks much larger.
Is there some advantage to this?
Looks like this fan is some kind of "cooling" fan - not designed and made to be used as DF in aviation. Also it's made of some material not designed for hi rpm and aerodynamic loads - it look like this fan came from some automotive field(radiator cooling fan?)
