Those are some wild looking fan blades.
I haven't read up on them yet. Is the tip shape for increased thrust or reduced noise...or both?

The Leap has 32k lbs thrust vs 25k for the CFM56. It has half the fan blades at 18 vs 36. It has 25% better fuel economy too. I think the fan is much more efficient but it’s also much bigger. It makes the strangest sound when spooling up but sounds normal at speed. [This message has been edited by Hudini (edited 03-30-2020).]

Thanks.
Civil aviation "leaf blowers" were not my job. I spent a good part of my civilian career as an aerospace engineer, (Pratt & Whitney Government Engine Business R&D), developing military jet engines and rocket motors so I now have more questions to go research on that engine.[This message has been edited by randye (edited 03-30-2020).]

I found a tiny flower in my backyard, a weed really, and brought it inside to take a picture.
