exactly. there's always the lesser-known sexiness/weight for any given wing.
Exactly. L/D means little if the wing is too heavy to fly.

dude, if you find pipe-flow fun... you're gonna love fiddling around with CFD and, if you're lucky enough, playing in a wind tunnel.

As it happens, I'm planning on designing my own wing, and it's going to look a lot like this description.
my best friend from college, who lives next door to me graduated with me at embry riddle and majored in aerospace engineering... trying to get him to use his degree and make me a wing...

By the way, on Sunday I just saw one of the most gorgeous wings ever. When you guys get a chance to see a 787 in person, you'll see what I mean.
You didn't get to see it in person, did you? If so, I'm jeleous, and you need to point out where you were sitting in the video

eurotrashdtm, I think the most important part of efficiency that you are missing is that L/D is not constant, but instead a function of airspeed. Therefore a setup that might be more effecient than another at one speed may be less efficient at a different speed. This is why there is no one correct answer as Mike said, and the wing setup must be engineered to match the application.

Yup. I took my grandfather, who was a 38 year Boeing employee. We're somewhere in the middle of the crowd during the seated part. Eventually walked up and looked in the back of the left engine, then walked around the back of the plane. I worked on emissions requirements for the 787, specifically for the APU.

The wings don't look particularly special from the front, but from the back or underneath, those raked wingtips are just wicked. The 3D compound shape is a lovely sight.

757s were built in Renton (subassembly and final assembly). The 787 is built all over the world, but final assembly is in Everett (with the 747, 777, and 767 for as long as they still build 767s). Renton built the 737, 727, and 707 as well as the 757 (and the hydrofoils). Now the 737 is the only plane being built there (the fuselages are built in Wichita and shipped to Renton by rail).

The only "7-series" airplanes not built at either plant were the 717s, built in Long Beach at the former Douglas plant.

Sounds like a great time. I'm looking forward to seeing one in person and eventually flying on them when they come into service. I really think the interior changes are going to make a huge difference in the flying experience.

Very interesting thread Thanks alot to the contributors... Now as far as OEM wings are concerned, are they just for looks or do they actually contribute to the vehicles performance? I.E. Evo, STI.. In the same context, does the OEM AP1 or AP2 wing contribute to performance? ( I personally like the AP2 wing )
