Winglets On The MD-80

Mon Aug 11, 2008 7:49 am

Hey all,

I have a question regarding the MD-80 and the winglets. These days it seems to be very popular to retrofit winglets on older airplanes. I was in CPH yesterday where there are a very big amount of MD-80. Of cause SAS still has alot of them but also other airliner is still using them.
So will the MD-80 ever gonna be retrofitted with winglets? If not then why?
I know they are pretty old but they are still a huge amount of MD.80 in use world wide.
Hope to hear from you  Smile
Best regards Emin

Not much use, but... there were 'Fake' winglets applied to this aircraft back in 2006 for the Farnborough Air Show.

Not necessarily fake, the company that developed the hushkit on that aircraft said they were developing one:

I guess they haven't convinced any operators to fit them.

After reading the article I makes me thinking why it hasn´t been a succes? Saving 5% fuel when only retrofiting the winglets seemse to be alot. Specially when there are so many "mad dogs" still flying......

I don't see it happening. The cost of the winglets wouldn't likley be recouped over the inservice time of the airplane for the major current operators; AA, DL, and SAS. All three are beginning to remove them from service.

Well, cargohaulers will use the MD-80 for a long time, so I think winglets can happen.

The wing on an MD80 is very flexable compared to the DC9 and would require an inordinate ammount of reinforcement in the fuselage to wing attach area and mid span area to support the additional wingtip lift generated by the winglets.
It all comes down to financial balance.
I don't see it happening either.

Are there presently any companies planning to offer cargo conversions to MD-80s?

Like who? Don't get me wrong, I like the MD-80 just fine and have oodles of time in it, but it has a small cabin cross section so I am highly dubious about cargo conversions. I cannot imagine that on an older aircraft with relatively short average stage lengths that financially there is any incentive to design and install winglets.

Old plane + Short legs = No winglets

But WN is putting them on 733s. Anyway, they can offer a noise reduction because they reduce needed takeoff power. At least the 737's API ones do.

Or increase climb rate and thus decrease noise heard on the ground.
