the dreamliner took off this morning. a bunch of us went out and watched it (surprisingly) lift off! It's been sitting in our hanger for a few months now, it was pretty cool to see it finally fly.

Holy smurfs....are the wings really " bowing" up that much or is it an optical illusion?

I wondered what shook our building this AM......I work @ the S end of the runway, just off Bev. Park Rd.

the wings on the 787 are actually bowed up. it doesn't look too strange until you see it next to a 767...

(I work at ATS at the south end of Paine field off 112th)

It was a very exciting day. The wings are bowed up but they also flex more than the aluminum ones. Almost everyone yesterday in the runway was commenting on how nice the whole plane, specially the wings, looked.

only the skin is carbon fiber. all the frame work and wing ribs are still aluminum. .
That is kind of a misleading statement. The majority of the aircraft structure comes from the carbon fiber shell. It ain't just replacing the "aluminium cladding"



good info here
http://mechanical-engineering.suite101.com/article.cfm/the_boeing_787_dreamliner

Composite Component Construction

The majority of the composite materials in the 787 Dreamliner are in the fuselage. Whereas traditional aluminum airframes consist of circumferential frames, longitudinal stringers, and skin sheeting, all connected with rivets, the 787 consists of complete cylindrical sections, each about 20 ft. in length. The construction of cylindrical "barrels" reduces the number of fasteners used in the fuselage construction by about 80%.

Oh and to answer Marty's question: LOTS
How much stress can you put on plastic before it breaks?

The 787 Dreamliner uses a variety of advanced materials:

•50% carbon-fiber composite, in the fuselage, wings, tail, and interior components
•20% aluminum, primarily on the wing and tail leading edges
•15% titanium, primarily in the engines
•10% steel
•5% other materials


we were making some of the only aluminum in the plane.
 
It's a lot like newer DH Bikes...lighter than the ones from the nineties, requiring less power to do the same work. oh, and yes the wings are designed to flex - yet possess a huge safety factor in strength.
:-) It was exciting to see... I'm an Industrial Eng on the Everett Flightline

Nice move. Next time I run into him I'll make sure to have a copy of "Fluidride: Ride like a Pro"
