Re: Hybrid metallic blade

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.

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.

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

Wish there were more info on it.

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.

@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.

Because of the increasing ubiquity of wearable technology, it would be easy to think that design of wearable devices is routine and involves common design and engineering knowledge. Missed efforts in development will be remembered once the devices are used in the field
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
Finalists have been announced for the annual Medical Design Excellence Awards (MDEAs), recognizing the best achievements in medical device design and engineering.
As governments, associations, and NGOs around the world seek to protect consumers, national and regional standards are becoming mandatory, challenging manufacturers and making testing and certification necessary for any product developed and brought to market.
No, we're not having delusions of grandeur -- this is the weapon of a Jedi Knight. And we're dying to see how it works. Today, we tear down a lightsaber.
