Re: Is fewer fan blades better?

Wing aspect ratio can't be generalized to engine fan blades. The cowling interior wall acts an end plate/super winglet suppressing the tip vortex. The physical dimension of a fan blade does not reflect its operating induced drag characteristics. Aspect ratio is the ratio between the width of an obj...

Re: Is fewer fan blades better?

I think it is just because the fan blades have gotten wider, therefor fewer blades fit into the same space. The frontal area is probably still the same. Just look at how the aspect ratio has changed.
