AIRBUS dropped program to add winglets to A320s after analysis (both Airbus- and WINGLET TECHNOLOGIES-designed winglets were tested) showed benefits did not offset additional weight and required structural reinforcement.

Quoting SkepticAll (Reply 1): Will this decison affect JBU's desire to equip their new A320's with winglets or are these modifications being done "in-house" so to speak.
I don't think that an in-house retrofit by JetBlue is likely. I believe that the problem was a structural one, requiring strengthening of the wing to handle the winglets. This strengthening offset the benefits and also makes a retrofit that much more difficult and costly.
I wonder how this decision affects the earlier talk of a 5% improvement in the A320 through various upgrades. This seems to be a major setback towards that goal.

EXACTLY. Airbus has a habit of building their a/c to the absolute minimum to meet specs. Thats why they had to cancel the winglets for the A320 and why they most likely will not be certified. Adding winglets adds extra stress to a wing and their wings are not strong enough to handle it. They break everytime. Same problem with the A380 and why they couldn't put winglets on that. They would have to strengthen the wing even more. Boeing on the other hand builds their a/c to exceed standards. The 741/2/3 had such a strong wing initially that when the 400 came out, they were able to add the extension and the winglet and still have a strong enough wing. The problem with the general public and people on here as that they base everything on orders. When it comes to building planes, Boeing builds them better. Airbus builds a weaker plane. That is why a large majority of Airbus's are leased and now owned. Companies dont have plans to keep them very long. A high up former engineer with northwest was in a meeting with my roommate during his internship and was saying that a 10 year old 737 has the same reliability as a brand new A320.

You couldn't be more wrong. Southwest doesn't spend money on fashion accessories. And why do you think Airbus puts "wingtip fences" on their A320s--to make them look fugly?
Quote: Southwest said yesterday that an analysis showed the 8-foot-high winglets, which add about 5 feet to the airplane's total wingspan, will allow its 737-700s to fly up to 115 nautical miles farther and reduce fuel burn. Southwest said it expects to save an average of up to 92,000 gallons of fuel per plane per year. http://seattlepi.nwsource.com/business/127079_air18.html
Quote: After flight testing on a 737-800 showed they improved mileage by as much as 6 percent or more on long-range flight, Boeing decided to incorporate them as a standard feature on the business jet.
"This is going to give the 737 a substantial performance advantage over the Airbus A320, especially in high-altitude airports.
Planes with the winglet technology will need less power on take off, he said, and that means less noise. And because of the fuel savings, airlines can put less fuel on their planes and more paying passengers, Clark said. http://seattlepi.nwsource.com/business/wing18.shtml

This is the typical difference between American engineering and European engineering. We optimize, you build large. Take the Dodge Viper for example: It has a 8.3 liters and produces 500hp!!! That is less hp per liter than my mom's Saab 9.5! Now take an European car with a similar engine: The Veyron. It has 8 liters and produces over 1000hp! That is the double! European optimization in a nut shell. In cars it is stupid, but in planes, as you have proven, it is worth the initial price.

Quoting Ukair (Reply 7): This just goes to show that winglets are nothing more than a passing fad, an aviation fashion accessory if you will.
Part of the problem for Airbus is that they already use fences to reach their goals. Boeing didn't use anything on the NG to match the Airbus for efficiency. So, adding the blended winglets gave them gains in efficiency over having nothing.
But for the A320, adding the winglets would only give them incremental gains over the fences, not as cost effective.
Further, from the pictures, Airbus looked to be working with smaller winglets, maybe to save weight and not have to add strengthening, but those didn't provide much benefit.
I never understood the small winglets in the pictures. Seemed like they were doing a half-assed job to just prove they don't work.
But Embraer, Boeing, Airbus and MD and others disagreed on other, non-A320 aircraft. Boeing is using the winglets to increase range on the 739ER over the 739, so if it were a fad, it would be detracting from range and Boeing would not be making it standard.
It's just that they don't work on the A320 in the way they were applied.
Of all the things to worry about... the Wookie has no pants.

True, but: "Completely redesigned a year ago, the Dodge Viper continues to symbolize extreme performance and extreme attitude. Blending brute power with classic yet outrageous styling, the Dodge Viper SRT-10 retains its title as the Ultimate American Sports Car - and as the icon of the Dodge brand."
But if you want to be pedantic: Shelby GT500 500hp in a 5.4L; M5 575hp in a 5L
Furthermore, I was not extrapolating to airplanes, I was just trying to make a point about the main difference between American and European engineering. Anyway, apreciated the comment!

I think it has a lot more to do with the fact that the wingspan is already at 79.8m, putting regular wingtips on it would have not allowed the plane to fit into an 80m box.

How new? Granted, part of that could be the winglets and the wingbox with the current wing to body fairing which was introduced on late built -300s, but I don't see what's so new about the 744's wing? For example, it still retains the old slats (are those Kruger Flaps?) and the triple slotted flaps and doesn't have, what could be considered now as Boeing widebody standard, double slotted inboard and one slotted outboard flaps and the slats similar to those of the 767 or 777.

Actually, the primary reason for the A320-style wingtips is to reduce wing bending moments.

Have you ever owned an American car? Most Europeans talk with their a**es instead of their brains when it comes to American cars. They have this perceived air of superiority because they don't know what they are talking about. In my well-over-a-million kilometers driving life, I have owned:
- European cars: BMW, Opel, Renault, Fiat, VW
- American cars: Ford (several models)
- Japanese cars: Toyota, Nissan, Suzuki
The best cars are, without contest, Japanse, followed by Americans, with Europeans last. Any Toyota or American Ford will outlast a BMW - easily. Toyota engines are at least one generation ahead in terms of technology compared with anything that European cars offer in similar price range (ALL Toyotas have VVTi engines, tell me how many European economy cars come with equivalent technology? Yes you can get it in a Porsche or a BMW, but what about a cheap compact or economy family car?). On top of that European cars polute more - don't believe? - check this study commissioned by EU government that compares motor vehicle standards of Europe, USA and Japan - link attached. Not only the standards for new vehicles are tighter in the US, the cars must be quaranteed to maintain these standards for 8 years. http://www.cemt.org/online/council/2000/CM0006Fe.pdf
An before you make any statement about my nationality based on the flag next to my name, let me tell you that I'm EU citizen, currently living in the US (and hence the flag). By profession I'm a mechanical engineer with 20 years experience, and yes, I have professional experience with car industry.
When in comes to design optimization, American engineering is as good, if not better, that European. Some examples:
- B737 models are lighter (empty weight) than equivalent A32x models
- B777 is much lighter than equivalent size A340
There is no "fat" in American design, on the contrary, if anything, Boeing airplanes are more optimized (lighter) than equivalent Airbus models.
