New Boeing 737 wingtip design
New Boeing 737 wingtip design
(OP)
Hello all,
I noticed that the new Boeing 737-Max 8 and other models sport a new wingtip design. We've all seen the currently fashionable winglet design where the outboard 10% of the wing is swept upwards, I assume to take the drag vortices off the main plane, but this new design has a similar winglet, but it is bifurcated with the aft portion swept downward. It is counter-intuitive to think this cleans up the drag model. I am hoping someone on this forum that knows aerodynamics can provide an insight as to the concept.
Just curious because it is such a different look. Hope to hear from someone. Have a great day.
Regards,

Difference being the 320 are small & go stright up & down while 737 are angled though arguably the straight up down is more a fence than a winglet as such.
Some aircraft have long used downswept tips "Hoerner tips" and were some of the earlier wing tip devices.

My guess is some combination of advances in CFD, FEA & materials but I could be wrong.

Are you able to edit pictures and make them a tad smaller? My screen's scrolling to the right by about 3000 pix.

There are a number of reasons for not just making the wings longer - for example 'structural', i.e. minimizing loading on the wings, as well as things as simple as fitting in the parking spots/on the taxiway at airports or fitting in existing hangers....

Alternately, you might want to try Chrome, which seems to do its own scaling to keep things on the same screen
