Do winglets on a 737 type aircraft make it more fuel efficient than an A320?

What happened to Airbus’s trial of winglets?

I think your question is answered here.

An Airbus A320 of Air Blue in Karachi.In 2006, Airbus tested three styles of winglet, intended to counteract the wing’s induced drag and wingtip vortices more effectively than the previous wingtip fence. Adoption of the new winglets was expected to reduce fuel consumption by one to two percent. The first design type to be tested was developed by Airbus and was based on work done by the AWIATOR program. The second type of winglet used a more blended design and was created by Winglet Technology LLC, a company based in Wichita, Kansas as well as the third type.

Two airplanes were used in the flight test evaluation campaign. F-WWBA, the first A320 produced, has been retained by Airbus for testing, and was fitted with both the first type and second type of winglets.[6][7] JetBlue Airways provided the second aircraft, retrofitted by Airbus with both types of winglets.[8][9]

Despite the anticipated efficiency gains and development work, Airbus announced that the new winglets will not be offered to customers, claiming that the weight of the modifications required would negate any aerodynamic benefits.[10] In addition, the change in forces from winglets add additional stress to the wing which would require long-term study to determine if structural integrity is compromised.

But somewhere I read that to retrofit a 737 with winglets cost something like $500,000. A jet flying 12 hours a day could make it pay for itself, but a charter or freight 707, I’m not sure if they’d ever fly that much to make it cost effective.

Close, anything up to $800,000!:eek:

If winglets are so good, you may wonder why all 737s don’t have them. In fact 85% of all new 737s are now built with winglets, particularly the 800 and 900 series and of course all BBJs. It comes down to cost versus benefits. Winglets cost about $725,000USD and take about 1 week to install which costs an extra $25-80,000USD. Once fitted, they add 170-235kg (375-518lbs) to the weight of the aircraft, depending upon whether they were installed at production or a retrofit. The fuel cost of carrying this extra weight will take some flying time each sector to recover, although this is offset by the need to carry less fuel because of the increased range. In simple terms, if your average sector length is short (less than one hour) you wont get much the benefit from winglets – unless you need any of the other benefits such as reduced noise or you regularly operate from obstacle limited runways.

Its missing because a certain religion doesn’t like scantily clad women to be seen. So to fly into those countries in the middle east they had to remove said women from there aircraft .

Why not just put a veil on her and then she could be a belly dancer. They don’t complain about that do they!:D

My information is that N96670 is a J.3 probably still in Susquehanna, Pennsylvania!:)

The Air Force has a museum, but no P-51’s. How many did they have to start with? Good luck with your quest!

Don’t mind Steve, you will get used to his humour, welcome to the forum and you actually ‘fly’ for nine hours at a time on the sim? Are these real hours or speeded up? That’s right, I know nothing about the subject!

Having had a chat with the Air-Britain Piper expert he informed me that NO Piper Tomahawk or any other Piper aircraft has ever carried this registration ,so i assume it must be a mispole.

Thanks NPK, that was going to be my next suggestion as I found that N96070 was a Fuji FA.200 c/n 218 registration G-BBGW which crashed in Switzerland on 16/7/81, so I was waiting for the original poster to 100% confirm the reg. or plane identity.:)

So they are eliptical and the only other word I know that goes with that word is Spitfire? Good job he put the question marks after the listing title and by the way the spelling is SURPLUS!:D
