Winglets On 737/757-200 Replacement

Sun Jan 08, 2006 11:56 am

I do not intend on creating this thread as a poll, but just to discuss it.

Should the 737/757-200 replacement feature winglets (or raked wingtips) as standard? The 787-3 has blended winglets, and the 787-8 and 787-9 have raked wingtips. Since Boeing has been using these recently to improve performance of these aircraft, I think Boeing should perhaps consider using it on the 737/757-200 replacement.

What type of winglets:
Conventional winglets would probably not be the best option as it would extend the wingspan too much, and the 737 replacement is likely to have a new larger wing.

Raked wingtips may be better, but for an aircraft this size, would probably not be as good as blended winglets.

I personally think blended winglets would be the best option for this new aircraft family.

I think you are quite right. The blended winglets makes more sense. I am curious to see how the long the wingspan on the 737-E and A320NG will be. If the span is to long it will not fit into the existing 737 gates on allot of airports.

Y1 will not have enough range for raked wingtips to offer optimal performance. In shorter range aircraft, cruise performance is less important than weight.

One would think that if they can build a suitable wing that can fit in the current gates, then it would have a raked wing tip, if it couldn't fit in the gate, then it would have a blended wingtip. Raked is more efficient then blended, but blended goes up instead of out.

A question that I mentioned is whether they should be included as standard or optional. On the 737NG, they are optional, but I think they should be standard on the replacement.

I believe they should be standard. Maybe there will be an option regarding if the airlines will opt for a raked wingtip or blended winglets. The 737-E will probably match the range of the A319LR which is 4300 Nautical Miles.
