Blended Winglets

Tue Aug 15, 2006 5:37 am

I'm courious how much do they cost per set and how long do they take to retrofit a 737 or 757 with them?

I think for the 737 the retrofit costs around US$ 250.000.

I thought blended winglets were a structural part of the wing and can't be retro-fitted.

Definitely a retrofit item as they are being installed on B757s.

This does not even cover the labor costs. The average man-hours for the installation on the 757 is in the 4000 hr range and the 737 is typically 20 percent less.

The winglet kits are between 600-1mm dollars plus the labor for installation.

I hope this helps!

Flying safe with blended winglets!

The majority (or at least a good number) of the installed blended winglets are retro-fit I believe.

Check this website:

They make the blended winglets for the 737s.

Do they also make them for the 757 or is it a different company?

Aviation Partners Boeing also handles the 757 project. It is a very well put together kit. We just finished the modification in the middle of July on N801DM in YLW at Kelowna Flightcraft.

Well, in layman's terms (I'm not an AMT, nor do I play one on TV), they are structural--they're additional structure within the wing. It's certainly not as if they're bolted on to the last 3 inches of wingtip...

Southwest's -700s started delivery in 1997, without winglets, and IIRC the original order (for retrofits) was something like 80-100. Eventually, they started coming from the factory with them, for us, anyways...

Well, my understanding is a Blended Winglet is what the B767-400, B747-8 and 787 have. It's the added flair at the wing tip. The standard winglet is what the 747-400, 737NG's have, and what is being added to the 757.

Sounds like that's backwards, at least as far as the NG 737s are concerned, as they have the blended variety...

You have it backwards. The B764, B747-8 and B787 have raked wingtips. The 744 has traditional winglets while the 73NG and 757 have the blended winglets.

This is the company that designed the blended winglets for the NG and 757.

Almost right.

The 767-400ER, 777-200LR and 777-300ER have raked tips.

The 747-400 has traditional, Whitcomb winglets.

The 787-3 will have Boeing (not APB) designed winglets. The 747-8, 787-8 and 787-9 will have something that looks like raked tips, but they curve up a lot in front view.

Also, you missed the 737 Classic - APB offers blended winglets for these too. Southwest just bought 90 shipsets.

My answer was towards EMBQA due to his misunderstanding of winglets in general for the aircraft he listed. In responding to EMBQA my answer was correct.

Thank you for listing the other aircraft though.

It is Available as a Fitted assy on the B737,but the Wing tip area would need reinforcing which will add to the Weight.

This is always an interesting topic on anet for some reason.The Airways article is very good, they claim airlines can save between 75,000 to 90,000 gallons of fuel per year per aircraft! Brilliant!
