Hybrid metallic blade

@Ann: Thanks for this article.  It would be interesting to know more about the composition of the hybrid metallic blade, although I'm sure that since it's a proprietary design, Pratt and Whitney may not be forthcoming with the details.  From what I've read on some other websites, the blade is made from a composite, but has a titanium leading edge, along with metallic cross-ply reinforcement. (This is why it's called a "hybrid").  Interestingly enough, this is something that Pratt and Whitney has been working on since the 1970s.

Dave, I also wish we could have gotten more detail about the nature of the hybrid metallic material. Like those other sources, we do mention here that the blade has a titanium leading edge. It's possible that "hybrid metallic" means including plastic composites, but from what I've seen, that term can also mean metal-plus-ceramic, or multiple metals, or some combination of the above.

very interesting that the actual blades incorporate woven fiber into metalic structure.

Wish there were more info on it.

I'd also like to see how much more efficient this new engine is.  It would be interesting to understand how much more fuel this new design would save over the older design it is replacing.

It's still just a guess that the composites are woven or even that they include fiber; that's not been verified. It's worth considering, though, that composites have been used for wind turbine blades, although the stresses involved are obviously quite different.
