- Опубликовано: 4 июн 2024
- 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.
why did you tell anyone that
I think the raked wingtips for the 787 Dreamliner looks pretty awesome in my opinion. But again, i have never flown on a widebody aircraft in my life
Well why don't you go get on a flight to a destination and just fly right back? Are you in Pakistan?
@@iLoveBoysandBerries no. I am from Jakarta, Indonesia🇲🇨
@@nurrizadjatmiko21 how old are you? What's your Instagram?
It is pretty awesome indeed! Same here, I haven’t had the opportunity to fly on a wide body aircraft too.
@@ManLikeBishy same question above
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).
Sometimes it just makes sense to keep them all dark
@@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.
@@alooga555 common courtesy to close your shades after meal service. Doesn’t matter if the flight departs at 8am or 10pm.
I actually like the raked back wings better than winglets. It's sleeker looking, and very classy!
He finally starts to get to the point at 1:39.
Thanks!
😂😂😂
Has flown many times on the Dreamliner, and flying again 2. April. Very confortable airplane, mainly because of the low cabin altitude
What is low cabin altitude?
@@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.
787 wing is a whole winglet itself
No. It’s just a wing with a raked tip.
@@Ampersandrascott i think that is a joke
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.
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!
@@Ampersandrascott Winglets provide lift. That is why they work.
@@AmbientMorality Winglets create enough lift to counter their own weight. The main purpose is to control turbulence coming off the wing, which reduces drag.
@@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).
The most beautiful and elegant wings in the biz. Those wings are like a work of art.
So are the ones of the A350! Both great.
I've flown on a 787, and I was impressed with it. I'm a Commercial Pilot and have flown both as a pilot and as a passenger. Air NZ I flew the 789 and with LAN I flew as a passenger on one of their 788's.
How does the rake wingtip reduce vortices?
@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.
@@seanrollett6273 anyone can say that take works better and it reduce drag, more efficient etc but what’s the real reason for it? How does it work better than winglets?
I’ve flown on a 787-8 and 9. Both were great experiences - quiet and modern.
i have flown on SG airlines 787-10 manila to Singapore and back last June of 2019. That was our last overseas trip before COVID.
The Fiji Airways livery never fails to mesmerize me 😍😍
My dad is a 787 FO so I know a lot about it. Excellent Video!
I love the 787Dreamliner!
It's one of my dreams to fly on a dreamliner.
rhyme well
Great video!
Huge engines. Amazing. Thanks, Thailand Paul
I flew on the dreamliner a few days ago from Bogota to Paris
Such a comfortable plane
I've never flown on any other widebody and I wonder how they compare to the 787
Was always curious about that
Good question
I was impress by how quiet this plane was during take off. American was using it for many domestic routes during the pandemic
those wing tips are really pretty for me
nice sharing 👍😁
Vietnam Airlines have about 7 or 8 DreamLiners and the pleasure of frequently flying from London to Ha Noi is a fantastic experience.
Even Embraer uses the raked wingtip for the E2 whilst Airbus is yet to try it (A350 uses blended winglets)
I have never flown on the 787🙁. Hopefully will break this cycle. But the wings arch while in flight where the tips are almost in the positions of the winglets😃.
I believe this design was first used by McDonnell Douglas on the MD-80 series of aircraft.
Idk but it was first used in the 767-400ER
I flown on this aircraft last week, by far the best aircraft I have flown on
Can an airplane manufacturer patent a design like the winglets etc?
I love the 787 and the A350 .
Yes they can just like how Boeing did with the engine chevrons
@@theskyline1425 Interesting. I thought that would have been something the engine manufacturers did rather than Boeing.
@@ioanekoroivuki543 well Boeing and Nasa were actually the ones who researched on the effectiveness of chevrons
@@theskyline1425 I did not know that. That makes sense then.
I think that’s how Boeing loves to design their Aircraft, and I love it that way too!
How does raked wingtip reduce vortices?
I was browsing through RUclips suggestions came across Iraqi Airways, so Google for more information I was surprised by various types they have used for there fleet. The one type caught my attention, Imagine boarding an IL76 for your next flight.
Can be a topic for your next video.
It does. They are blended in the wing. 🙂
Flown on a 788 once with BA from LHR-YYZ, back in 2015.
The raked wing tip started at NASA about 30 years ago with the scimitar wingtip. It was actually proposed for the C-5 in the 1960s but the Air Force thought it was too delicate.
I wonder what the Air Force thinks now
Can aircraft that go ~0.85mach like 787✈️ have delta wings but keep the turbofan engine (w/out afterburners) ?
Flew an Aeromexico 787 from Cancun to CDMX. Best aircraft ever.
I mean…they kinda look like winglets when the wings are flexed in flight
p8 posideon got them too. and its a 737 thing. i think it has to do with radar tho.
I have been on etihad 787 and oman 787 but the wing keeps lifting
“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.
Can anyone imagine how an Airbus a350 would look in Air Canada’s black livery 😯
(Black livery meaning the livery the tail and the front cockpit windows are black
I flew on the Dreamliner lots of times.
Will fly in Dreamliner soon on april 19 its 787-10
Been flying with 737, 747, 777, 787, A319, A320, A321, A330, A340, A350, A380, Embraer 190, ATR 72 and a few more that i can't remember the names on :-)
Congratulation! you really dedicate your lives to flights. But you need to also ride Russian planes, my first and onlyu one was Antonov An-148
Adding some features sometimes just to gain attention of buyers,
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
How does raked wingtip reduce vortices?
Raked wingtips👍🏽
what winglets?
Excellent airplane travel several times with Norwegian American Airlines and Avianca.
I have also flown in Air India Boeing 787 - 8 Dreamliner from Singapore to New Delhi, India.
Racked wing tips, found on the 777 and 787 are equally as effective as winglets found on the 737 and 747.
Only the 747-400 has them the -8 has raked wingtips
Can you make a video about the China Eastern airlines Boeing 737 Crash?
It’s the same reason that the 777 2nd generation doesn’t either and it’s also the same for 777X when the wing is unfolded
I have on two variants, one on domestic and two international routes
The B788, I was on China Southern Airlines flight CZ3417 bearing the rego of B-2788 on 31/03/15 from ZGGG to ZUUU.
The B789, I was on Japan Airlines flight JL771 and JL772, for JL772 on 06/01/20 from YSSY to RJAA bearing the rego JA863J, and JL771 on 21/01/20 from RJAA to YSSY bearing the rego of JA865J
Why Doesn’t The Boeing 787 Have Winglets?
The B777-200/300: Am I A Joke To You?
To be honest the a330neo's winglets are a biggest variant of the 787 lol
Can we have a video on why planes have “three wheels” in the configuration these generally have? Why doesn’t it fall over like three wheeled cars do?
3 wheeled cars absolutely do not just fall over
@@qwerty112311 Only when turning at higher speeds?
did u ever see “ indian auto’?😂
Regardless of the facts...
The 787 wings and winglets are sexy AF.
The 787 is such a wonder of an aircraft in terms of technology and it is so beautiful. I enjoyed spotting it up close on final approach at my local airport; You can check out the video on my channel to see it.
Please consider subscribing to the channel too. thank you!
It's whole wing is basically a winglet
"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".
Laymen worry more about winglets than airlines.
It's not like the other planes... 😔😔😔😔🤚💥💯💯💯👌
The 737's flat windscreens from the 707 of the mid 50s don't exactly help.
Will avoid the 787 anytime I can. The three time I was on it they blacked out the windows without any recourse for me or others. I could not look out the window which is something I paid extra to do on an AFTERNOON flight over the Atlantic. I would rather fly a 777 or 747 or A350, actually ANYTHING over a 787 if they are going to blackout the windows against my will.
Why are their no winglets on the tail wings?
Because the horizontal stabilizers are not loaded much, in fact the tail lift, for stability reasons is negative
@@arturoeugster2377 but it would increase fuel burn
Because Boeing know what they’re doing and decided not to install them.
aww, boeing 787 no winglets but airbus a350 have winglets. boeing 787 is curved wings
747 8 doesn't have winglets
Nope but it has raked wingtips
Why doesn’t the 777 have winglets.
Idk
787 has seats of toyota prius. It's an horrible experience for economy class people..
Answer : because Boeing thought the prototype artist rendering looked better without them and when it came to building the plane they forgot to add them
Do not tell me?
This video is needlessly long stretched
