A380 Winglets

Mon Jul 30, 2001 12:13 am

Hello, does anybody know the reason because of which Airbus decided not to apply winglets to the new 380???

I think it's strange because it decided to use them on the 330/340.

What about Boeing and the 777?

I think we will see some kind of "winglet" on the A380. Right now all we have seen is the "wing fence" like on the A320.

The 777-200/300LR will have "Raked tips" like the 767-400.

I think they will put winglets too, remember the first A-340 pictures didn´t have any, and then they put some. Maybe they still don´t know how they will be so they don´t put any yet.

Winglets do no benefit to short or medium haul flights. That's why 777 was not designed to have winglets. For 772ER, 772LR and 773LR, I think Boeing should put winglets on them. However, I don't understand why 737-800 has winglets option. Anyone know why?

Maybe the A380 will have the type of winglet seen on the early A300 model. We all think of the 747/A330/340 and then the other A320 winglets. There are many options.

Red Panda,

Boeing did studies of the winglets for the Boeing Business Jet on a 737-800 ( I believe the #1 738 off the line ) and discovered that it could improve the range by a small margin and increase payload carrying capability. As well as reduce drag by a small percentage. Over time, winglets of the 737NG will save the airlines money.

Also, in regards to winglets on the 777, from what I understand, until recently Boeing was not big on incorporating winglets on their aircraft. I don't know why. I fact, when developing the 744, they really couldn't increase the wing span of the 747 because of structural integrity so thier only option was to put winglet on the 744. With the 777, if you look at the top view of a three-view drawing, you will notice a slight raked wingtip. It really doesn't have a conventional wingtip. I think this is where the got the idea for the raked wingtip for the 764 and the longer range versions of the 777. Boeing also was going to incorporate the raked wingtip on the 747X family as well.

I'm not a real aeronautical engineer, I just play one on Airliners.net.

Yes, I used to like planes with winglets, but as more and more acfts have winglets, you would start to miss those without winglets such as 747 classic. Now, I start to love 747 classic because of their wing shape and the stick attached to the end of the wing tip.
