New 737 Max Winglet

Received the standard Boeing PR press release about the 737 winglet proposal,


Boeing Designs Advanced Technology Winglet for 737 MAX by The Boeing Company, on Flickr

They are claiming that this will achieve an additional 1.5% fuel savings.

What grabbed my attention was not the MD-11 style winglet, it was the blister for the nose wheel like the A330F ?

Is this a new feature ?

Loving that winglet. I think I like it even better than the blended winglets on today's 737s.

I guess it's the best method for weight and cost savings. I would think they could just tweak a few inches from the bay to get it to fit.

So now the 737MAX will have between 11.5 to 13.5% improved performance. I wonder if there will be other tweaks to improve the performance even further. This kind of update could be incorporated before the MAX enters service.

Interesting. It looks like they have done some changes in this angle as well.

Damn if that's really gonna be the final winglet setup I must say it looks really really cool!

Also in the picture of oykie the blister looks very subtle.

It is interesting that Airbus have moved from a fence to a winglet, yet Boeing are moving from a winglet to a combined fence/winglet.

Are the Blended Partners designing this or is it an exclusive Boeing design?

With Airbus going for a blended winglet on the A320 family I thought things were going to get really boring with winglet designs but this looks very interesting. The MD-11 winglet was always my favourite so I hope we actually get to see this on the MAX.

Is the rear fuselage (behind the wing box) widened and more square? It looks like the belly of the plane leading up to the tail is much more square that a normal 737 fuselage.

If I'm not way overthinking this... is the 737-MAX being prepped to take containers in the rear cargo space?

Sure looks like it. There was talk earlier about the possibility of raked wingtips on the 737MAX, but I never imagined it would be in combination with the blended winglet.   

I'm glad about it though. I've done a few plane spotting classes to friends and I taught them to distinguish the 737 from the A320 by the winglets... With the A320 getting sharklets, it kind of ruined that.    Glad Boeing gives the the 737 now this, errr, raked winglet?   

Quoting planesailing (Reply 6):

I'm pretty sure this will remain a Boeing exclusive for a while, if not it would have been kept secret a little bit longer - and we might see it on the NEO otherwise

On the MD-11, the lower portion of the winglet seems to be foreward the upper portion.

http://en.wikipedia.org/wiki/File:KL...as_MD-11_PH-KCK_Ingrid_Bergman.jpg

This new Boeing modified design seems to have the lower portion abeam the upper portion, and nopt bend down as much of an angle as on the MD-11.

Zeke could be right about the blister on the lower nose of the B-737-8MAX he posted. But I don't see it on the B-737-9MAX picture oykie posted.

Either way, the MAX design is still a long way from frozen, as we all know. For all we know, none of these features could show up on the final design. Remember the first drawings of the B-787 from Boeing had a different nose section and vertical stabilizer.

yes ... Boeing announced a few weeks ago that they have modified the tailcone section of the fuselage making it flatter and longer (among other changes) ... basically they are cleaning up any aerodynamic inefficiencies that they can find in the 737 design

I've been curious as to which winglet change Boeing would implement. I find this interesting just as Airbus is committing to sharklets. This will probably force Airbus to update their winglet offering sooner than prior plan...


Quoting zeke (Thread starter):

That is impressive. The original APB winglets exceeded all expectations. Boeing needed to do this.

I'm personally curious as to what weight reduction will occur. I know of more than a few engineers who have been brought on for commercial aircraft weight reduction. After the 748 and 788, they could be employed on the MAX...

Quoting oykie (Reply 3):

One of several. For example, the tailcone will look more like the A320's than the current 737NG's.

It does, I doubt it will be that subtle in the final form.

It is there, but the rendering obscures it. Something has to be done for the longer nose gear...

Love it! I had pondered weather Boeing was eventually going to go this direction. In a previous thread about the MAX, I included a link to APB's ideas around the 'Next Generation' of winglet. Looks like the only thing Boeing didn't adopt (yet) from that proposal was the "scimitar" ends.

We'll obviously have to see what truly gets built. However, from the updated renderings found at http://www.newairplane.com, it appears that it is limited to a bulge on the nose gear door.

Yes, there is a bulge but it's not as pronounced as on the 330F.

If A330F has a blister, at best the MAX has a bump or a knock.

I would think they'd be directed towards the 789. Boeing's CEO is crowing that the weight reduction on the 789 is making it easy to do the 7810.

Quoting dash500 (Reply 16):

Seems the word "shark" has to get worked in. We've already had shark fin for the orignal 787 tail, and sharklet for Airbus's winglet, so we can have shark nose for the new 737MAX.

I call dibs on shark nose!

102 nomadd22 : One thing is for sure. The MAX will join the 747 and 380 as the most recognizable airliners in the sky.
103 GSPSPOT : I have to say I think the blended winglets look much better - more graceful, esp when a plane with them is gently touching down.

105 columba : Interesting is that the video is mostly focusing on the larger variants 737-8s and -9s, the -7 is only seen very briefly at the airport. In flight the

107 lightsaber : I think that the aerodynamics help. It occurred to me that the 'droop' is going to really help the climb fuel burn! One issue with winglets has been
108 kamboi : I prefer Winglets (744, 340, 330) as compared to Blended Wings and Sharklets.

112 yellowtail : Wheel well doors = weight. The tradeoff with drag might be in favor of leaving them uncovered.
113 XT6Wagon : Also quite a bit of cost over the lifetime of the airframe, with extra motors, hinges, sensors, wiring and plumbing that go with them. A "hubcap" and
114 garpd : To use an old engineers addage: If it isn't broken, don't fix it.
115 aotearoa : Wow. That wingtip extension (winglet, whatchamacallit) is damn ugly!
116 Post contains images USAF336TFS : And I think that wing tip is very cool looking!!! Funny how we see things differently.
117 Post contains links and images AirPacific747 : Yes because I also think it is damn ugly.. I guess this new design is either one you love or hate.. no middle road.. To me, the 737 is like a car tha
118 garpd : I'm glad you're not in charge at Boeing. You'd drive them into the ground with the logic you just displayed. You're talking purely about aesthetics.
119 columba : Well, I would not say the 737 is pimped too much. It is more of a comparision of a standard Golf Mark I (737-100/200) with the next generation Golf M
