Comment on Airbus previews next-gen airliner with bird-inspired wings
echodot@feddit.uk 5 weeks agoI don’t think the number of blades is really important. After all if you just keep adding blades eventually you would get to a point of diminishing returns. That’s around four blades which is why most only have four blades, unless they’re made out of incredibly light material.
So if you have a lot of extra blades there probably is some additional engineering going on to make use of those extra blades in some way.

I was meaning that the blade count and detachability was the difference in definition between turboprop and propfan/open turbofan, not that it was necessarily the thing making the engine more efficient.
