Thanks, bobjengr. I agree, this is an exciting area of composite technology advances.

Dave, you're welcome. Fewer engines definitely contribute to much of the overall weight savings. Fuel efficiency depends to a great degree on weight of the plane and the engines, just as it does in automotive lightweighting. But there's also the redesigned engines, with "a very high bypass ratio and fewer stages and airfoils than other engines," as we mention in the article, which contribute to greater efficiency. There's a lot of info on the site at the link we give.

Cadman-LT, that's right, this is the same, long-awaited CSeries aircraft that's been in production for some time. Now there's a lot more info available about it as its first flight approaches.

I certainly agree--another great article.  I am definitely impressed with the cockpit and instrumentation locations.  The layout seems to be a significant improvement relative to some I have seen.  I certainly appreciate you giving us periodic updates on composite materials and where they are being used.  I feel efforts to lighten systems will certainly be an ongoing proposition and composite materials will be in the forefront of that effort.  As strength-to-weight ration improve, we should see additional interesting applications for composites.

Ann, so this is basically just a new engine and testing. No new aircraft. Just some new materials to reduce weight in the engines?

Hi Dave, just tagging along so I get to see any answers on that :-)

@Ann: Thanks for another great article, on what promises to be a very interesting aircraft.

I was struck by the statement that the CSeries weighs 12,000 pounds lighter than other aircraft in its class, and that 2000 pounds of savings comes from using lightweight materials.  Where does the other 10,000 pounds of savings come from? Maybe from having fewer engines, like you mentioned in the article?

It's also surprising that a 2000 pound weight reduction -- which, given how much an aircraft typically weighs, is probably only about 1% -- would lead to a 20% increase in fuel efficiency.  I'm guessing that the weight reduction only accounts for part of the fuel efficiency improvement.  Any ideas where else the fuel efficiency is coming from? Maybe the PW1500G engines?

In this slideshow's latest crop of new bio-based and renewable plastics and methods for making them, some materials can even be completely recycled several times without loss of original properties.
It's probably too late to buy one, but some lucky people will soon be the owners of only 50 electric motorcycles made entirely with 3D printing from a super-lightweight aluminum alloy.
Oak Ridge National Laboratory has developed a surface preparation method to improve joining carbon composites with aluminum, with potentially far-reaching ramifications for high-volume industrial applications.
Our latest crop includes ABS alternatives, tougher PLAs, flexible plastics including a flexible nylon, polymers with better heat resistance, and the first biocompatible resin for desktop 3D printing.
New and improved fastening methods are helping engineers join plastics, composites, and thinner metal sheets in a variety of product assemblies.
