Why Doesn’t The Boeing 787 Have Winglets?

Last year marked 10 years since the Boeing 787 ‘Dreamliner’ family entered service with Japanese carrier All Nippon Airways (ANA). The next-generation widebody is known for being one of the most modern and efficient aircraft in the long-haul market. However, it manages to achieve its efficiency without the use of winglets. But why doesn’t it have them?

I was flying with Qatar Airways once and had 2 days to go until flying. I just wanted to check my flight status and went to manage booking and when I saw the aircrafy type, I was screaming in happiness. I was also transiting in Doha and the previous two flight had 777-300ER's and the flight to Doha was a 787 and the flight to my final destination was an A350-1000. This was the best day of my life and will never forget it.

[@stephenjacobs5640]

why did you tell anyone that

[@alooga555]

The first time I saw the 787 wing in flight from my window seat, it looked so beautiful like a work of art. I also love the push button window shading (as long as the flight crew do not override and keep all the windows dark).

[@JAYfromTHEworld]

Sometimes it just makes sense to keep them all dark

[@alooga555]

@@JAYfromTHEworld True but I did not appreciate it when the flight crew of my flight from Denver to Tokyo, which left at around 1:30 in the afternoon, darkened the windows for the first six to seven hours of the trip, even though it was still light out. ANA flight crews never do that for some reason.

[@burnedbacon3989]

@@Ampersandrascott i think that is a joke

[@jesperdahl3668]

Has flown many times on the Dreamliner, and flying again 2. April. Very confortable airplane, mainly because of the low cabin altitude

[@erickscott5732]

What is low cabin altitude?

[@jesperdahl3668]

@@erickscott5732 As an example, the B737 when flying at 40.000 ft. the air pressure in the cabin is equal to the air pressure at 3000 meter. Meaning the air density/ pressure you would feel, as if you were standing at a mountain top 3000 meter above sea level. The cabin altitude/ pressure on the Dreamliner when flying at 40.000 ft. is only 1500 meter, witch mean you will not feel pressure in your ears, and you will have more oxygen to breathe.

[@Jet-Pack]

Winglets are good when the wing span is limited. For the same wing span a winglet is more efficient. But if wing span is not limited then the raked wingtip is better, after all a winglet doesn't produce an upward facing lift vector.

[@Ampersandrascott]

All the winglets do is minimize the wing tip vortices. They don’t really provide any lift, and barely pay for themselves. The raked wingtip is much, much better. HOWEVER, the -400 is easy to pick out of a crowd!

[@AmbientMorality]

@@Ampersandrascott Winglets provide lift. That is why they work.

[@Ampersandrascott]

@@AmbientMorality Winglets create enough lift to counter their own weight. The main purpose is to control turbulence coming off the wing, which reduces drag.

[@AmbientMorality]

@@Ampersandrascott Yeah, I didn't word that well. For a given alpha a winglet allows the wing to generate more lift across its entire span. On an actual plane, of course, that means that the angle of attack can be decreased. But the same thing is true of a raked wingtip, which also allows the wing to generate more lift across its entire span (for a given alpha).

[@markinchs3629]

I’ve flown on a 787-8 and 9. Both were great experiences - quiet and modern.

[@LordBagdanoff]

How does the rake wingtip reduce vortices?

[@seanrollett6273]

@Bi Han The raked wingtips work better than winglets/sharklets because there is less drag, in thus helping the 788/9 with the 20% less emissions. Boeing chose this over winglets because there are less parts to put on the wings, and also the raked wings work better to reduce the wingtip vortices.

[@LordBagdanoff]

I think that’s how Boeing loves to design their Aircraft, and I love it that way too!

[@stephenwalton7079]

“A properly designed wing doesn’t need winglets.” John Roncz. He was the aerodynamicist that designed the Routan Voyager and a bunch of other things with Burt Routan. Winglets came to the fore when oil went up. A design house in Seattle filled with ex-Boeing engineers figured them out. Not all wings can accept the retrofit as spar loads and construction come into play. When Boeing first started offering winglets as retrofits, they wanted to charge a sizable percentage of the calculated fuel savings but got very few buyers. When the airlines, their bread and butter got stressed by fuel, Boeing finally relented to pretty much the cost of producing the refit kits. Interesting tidbit. At United Airlines, the performance engineers calculated the winglets on the 747-400 were useless and wanted to remove them for maintenance and weight savings. This idea was torpedoed by marketing who said they had poured fair money into convincing business travelers that the winglets were the sign of the latest and most advanced aircraft engineering. The winglets stayed.

Does raked wingtip have a tradeoff of longer span compared to winglet?

Yes but it allows the wing to have a bigger area which is better. Even Embraer uses it for the E2 in 3 different sizes for the 3 variants of the family

"Raked wingtips" can be categorized as "winglets". Similar to bent-up or canted-up winglets, those raked wingtips are also not a main wing component with slats and aileron. They are an extension for aerodynamic reasons = to reduce induced drag. So they are a "flat winglet".
