Why Boeing Has Winglets And Airbus Has Sharklets
HTML-код
- Опубликовано: 14 май 2023
- If you have ever looked at an aircraft, you might have noticed a variety of designs on the end of aircraft wings. If we were to describe these designs to a child, we could say that some wingtips are tall and thin while others are more short and stubby. Others have extensions coming from both the top and bottom. These protrusions are called winglets on Boeing aircraft, but they go by the name of Sharklets on Airbus aircraft. Ultimately, however, both provide a significant role in reducing drag. But how do they work, and what exactly is the difference? Let's explore this topic in today’s video!

Fun fact: as soon as any aircraft crosses into Australian airspace, they are automatically called sharklets, croc-lets, or snakelets.
I guess yall havent unlocked Spiderlets yet
@@YukariAkiyama I wanna see what spiderlets would look like
For some reason, when the 737s first got wingtips, it would be specifically detailed on the itinerary here in Aus. I didn’t think it was particularly relevant to my flight, to be honest!
That’s an odd name, I’d have called them Chuzzwazzers….
Roo-Lets
And Koa-Lets
Would've been nice to hear more about the design of the winglets on the Max & why they have 2 points on them instead of 1, one going downward as well as up.
Pretty much looks more than anything else. The function of winglets is really pretty trivial but once they were introduced even though their function is minuscule, they look neat and since the flying public has an overbolwn notion of them doing something that's important, airliners have left them on.
Video to watch posted by the channel Mentour Now!. He talks about these devices. Basically they're trivial, look neat, but yes they do add a little functionality in the way they break up the pattern of air moving over the wing which is air curling back over and around the top of the wing and if I remember correctly it's a little better for stability to break up that air flow. But for the very first statement made about drag, not so much.
EXCELLENT channel, Mentour Now! and also his main channel Mentour Pilot. That's the first place I would go for anything dealing with the airlines.
@@johndoh5182 mmmm.. split scimitar adds an extra 2% of efficiency to the 4% reduced fuel burn of sharklets...there's a reason Ryanair is spending $500K / plane on the addition of them. nothing on planes is really there for 'looks', especially when looking at Ryanair, they only spend money when they need to. i have to disagree with your comment, and hopefully that answers the parents'.
@@johndoh5182Try aswell the channel for Sam Chui😅, you will love it
The ones underneath optimise for flying over Australia :-)
@@johndoh5182 that is so inaccurate it hurts
Speaking of winglets, I recall the A330/A340 program initially had similar split scimitar type wingtip designs found in the A310 and A320 programs, but the A340’s engine problems forced it to have large wings just to help lift it off the ground. Since both the A330 and A340 were co-developed at the same time naturally they chose the similar polygonal wingtips found in the B747-400 in order not to screw with the aerodynamics further. The A380 was a standalone design, so it’s not subjected to compromise changes in its wingtip design.
its cool that the md-11 had spilt scimitars
The A310 and A320 do not have Split Scimitars. They are called Wingtip Fences 😉
Have you ever seen a scimitar? The A310/320 wing tip fences look nothing like it
I heard that 787 and 777's raked wingtips are optimized for long-haul flights (cruising), while the blended winglets of 737 (and the like) are more optimized for short-haul flights because their impact is greatest for take-offs.
If that’s the case, I wonder why the new Embraer E2 aircraft have raked wing tips instead of winglets like their predecessors.
Yes, the wingtip vortices exert greater drag at lower speeds (take-off and landing)
That's correct
@@PhorzaSky maybe for it's increased range? I found it interesting too!
That's correct
The Airbus A310-300 was the first airliner with wingtip fences in 1985. Other Airbus models followed with the A300-600, the A320ceo, and the A380. Other Airbus models including the Airbus A320 Enhanced, A320neo, A350 and A330neo have blended winglets rather than wingtip fences.
I think the wingtip design of the A350 is among the most visually appealing. I know absolutely nil about physics. To me, it's all about aircraft appearance. Perhaps I'm shallow and superficial! I enjoyed this video.
I love the 787’s raked wingtips. That beautiful sweep when you look it from the cabin will never get old for me. Hence why i always love to sit at the very back of the mid-cabin when flying on the Dreamliner
How are they effective compared to winglets?
@@LordBagdanoff The idea is to minimise the size of the wingtip vortex, which allows for minimum drag. The 787’s raked wingtip is sharp at the end, meaning smaller surface area for the upper and lower air streams to meet, significantly reducing the size of wingtip vortex.
@@magnustan841 hmm aren’t winglets sharp at the end as well?
I only fly premium economy or business on 787's now, that's the one thing I miss about sitting further back. If I sit at the back of business, I can get a decent view with my GoPro stuck on the window though. They truly are a thing of beauty to watch, they almost flap a little like an eagle soaring through the sky.
I agree i LOVE the raked wingtips on the 787s and on some of the triple 7s 💙💙💙💙💙💙
What about the winglets Airbus used on the A330 and A340 or the Wingtip Fences they used on some A300s and A310s as well as on the A320s and A380s?
Some of them came out much before 2000…
That is true, and the A300B4-600 also flew first with wingtip fences and also entered service in 1987 before the 747-400 took to the skies even. The A320-200 is just a few month shy of the 747-400, too. Simple Flying, I guess. ;)
I’m fairly sure that the Airbus A310 was the first commercial jetliner to have these devices. Whilst not the same style at later versions the wing tip fences on the A310 which were then introduced on the A320-200, A300-600 and A380 all serve the same basic function. The sharklets on the A320 are basically an improved version of the fences on earlier models.
Fences were an early attempt to effectively 'block' the vortex, which never works very well, the extra parasitic drag almost always wins out, that's why they were so tiny, and at that size they're basically pointless, hence why airbus stopped using them. The winglet uses the flow pattern produced by the vortex to direct the lift vector forward and produce 'induced thrust', which is why they get better efficiency for a given wing bending moment as stated in whitcomb's paper.
Stretching the memory a bit with that, but think you are probably right. I know you definitely right that the A320 only introduced them with the -200, as I was very involved with the -100 intro to BA service and and all 5 of ours (G-BUSB,C,D,E & F) didn't have winglets or whatever you choose to call them
Seem to remember when introduced on the A310 became designated -300
Raked wingtips,the latest and greatest..
Especially on the 787..
The dihedral and graceful curves on that wing flow nicely into the wingtips..
How are they effective compared to winglets?
@@LordBagdanoff Basically, the wing is just better designed from the get go as allowed by better technology. The way the wing ends improves drag without the need for winglets. I've also heard that winglets have improved efficiency for shorter flights, while the raked wingtips have improved efficiency for long haul flights. Not sure if this is true. Maybe winglets are overall more effective, but the extra weight is more of a penalty for long cruise times.
Stunning to see for sure, the most graceful bird in the sky.
@@zlm001 I think the thin rake, especially as they bow so much, creates the same effect.
My vote for best looking winglets goes to the A350. It appears to be more integrated into the wing design compared to the 737, 757, 767, 747, A380, A330ceo, A320ceo and neo, E-series, A220, C919, MD-11, which all look like it was “tacked on”. The 787’s and 777-300ER’s raked wing ends doesn’t seem to be wingtip devices, but more like wing planform designs.
Im pretty sure you'r right, winglets are indeed bolted on
What the 767-400ER, 747-8, 777 2nd generation onwards, 787 and Embraer E2 uses is raked wingtips
Honestly the 737-NGs is eben better, those aircraft just Look wrong without them
Have a look at some competition glider winglets. Obviously not quite the same case as airliners, but DG's neo winglets (no relation to airbus neos) and jonker sailplanes' winglets are stunning
BRILLIANT explanation - THANK YOU!
I like the raked wing tips from the 787s and the 767-400s plus the 777s.
Once I flew a modified two-seated glider plane (Twin Astir 3) that had the outer wings bent upwards by 12° according to Prof. Richard Eppler's research. The plane felt fantastic to fly and was so stable that one could take away the hand from the stick while thermalling. In the meantime, many gliders also have winglets, mostly those in classes with limited wingspan.
the 767-400ER has crazy huge winglets lol
The 767-400ER has raked wingtips like the 777-300ER and 787. The 767-300ER has the huge blended winglets you’re thinking of
I knew the inventor of the Winglet wing enhancement. It's primary purpose was to decrease the wingtip vortex, caused by the mixing of the high and low pressure airflows exiting at the tip. The Winglet introduces a countering vortex to reduce the primary, and this reduces the overall drag of the main wing, and increases efficiency.
I thought the MD11 incorporated the winglets before the 744s 🤔🤔🤔🤔
Earlier A350s have a slightly different sharklet than later ones. How easy would it be to retrofit the latest A350 sharklets onto an earlier A350? Would it be as easy as fitting winglets onto a 737NG?
5:51 - 😂 You can almost imagine the narration used in a chewing gum ad... Chiclets.
Intreresting video !!! ❤
Very nice homage to Pan Am... even without Winglets being exhibited here on the B747.
The 777x and 787 ranked wingtip stands out for me, it look like an albatross 🦅
I recall that efforts to delay and reduce tip vortices were made back in the middle of the 20th century by putting flat plates on the wing tips of some relatively small aircraft ; it was a failure . The plates increased weight and profile drag and merely formed a core for the vortices. Since aircraft of the time had a lot of room for improving profile drag it took a decade or 2 to revitalise the subject. As stated, In cruise a tip vortex is created by air spilling horizontally off the under wing tip instead of being defllected down from the trailing edge resulting in a loss of lift. The object of any of these tip devices is to reduce this spillage and the passage of what is left into the low pressure air above the rear of the wing. In short if they can delay, or unwind , the vortex until aft of the wing then the wing can produce the same lift at a lower angle of attack reducing induced drag. The negative side is the combination of extra weight, profile drag of the device and any induced drag from redirecting airflow. Just like take off performance can be improved by loading payload near the aft C of G limit so reducing the negative lift of the tail plane at rotate the values involved are proportionately small but have long term reward. The entertaining variation in wing tip adornments is because they are fine tuning of performance ; not fundementals. It is worth remembering that the inconvenient vortices in this subject were an essential source of lift for Concorde's significantly different wing in approach configuration. Also worth remembering is that the Rutan Voyager scraped one of its similar devices off using the runway on take off but went the 24,000 mile way home to get it fixed. In appropriate conditions, it is possible to watch persistent condensation trails spiralling in the vortices produced by wings 3 or 4 miles behind the aircraft where the large diameter is no longer related to the tips of the wings but the weight of the aircraft. It is a pity that business politics can successfully challenge technical achievement and relevance.
Because of this video, i want to know more detail on Airbus' and Boeing's cockpit windows design difference and it's APU.. is it the same purposes as their wingtip(s)?
I wondered that too. Even in the Boeing fleet, the apu designs vary
Both look good
Should do a video on how raked wingtips work
nice
What’s the efficiency difference between the split scimitar type wingtip and the „regular“ winglets
I don’t get why Airbus hasn’t tried raked wingtips given the success Boeing has had with it. It’s good for widebodies in particular
It's possible Boeing had a patent which prevented Airbus from going down the path of raked wing tips. That said, it might be wing span the prevented Airbus from doing this as to fit them in certain size airports.
A330neo?
@@ameerali.ouarda not the same
the a350 and a330neo have something similar but i dont know what its called
@@747simmer4 It’s a type of blended winglet attached to an otherwise ‘normal’ wing. Even Embraer has decided to use the raked wingtip design for the E2 in 3 different sizes so that each variant has been optimised best (the shorter variant also uses a smaller P&W GTF than the other 2 variants)
Would it make any difference in fuel efficiency if the horizontal stabilizers have winglets/sharklets? After all, the horizontal stabilizers could be considered some type of extra wings at the rear of the aircraft where vortices could be created as well.
not really. the horizontal stabilizers aren't exactly air-foil wings thus they don't really create significant lift. They are merely there to direct airflow. you could say they are like fins on a rocket or like a vertical stabilizer attached horizontally. Further more: the engine blast may travel across them. add winglets and you add another vertical surface the blast can interact with making the plane less stable on its yaw axis
That would cause a stiff aircraft to fly. It would make it more stable and by that less agile. Stabilizers are negative wings. They give no lift, that's just for aerobalance. To compensate on higher speed
Why no sharklets on horizontal stabilizer and top of rudder?
Must be vertexes there too
Ironic that the Wright Brothers seemed to have studied more about air flow issues than Boeing and Airbus took a 100 years before they took a look at it. And they were bicycle makers with modest wind tunnels and no computers.
My favourite is the A330 ceo winglet✈️👍🏾
That Advert was wild
My favourite wingtip design as the one A. Bowers et al tested in 2015 at NASA. 10% lower drag for a 30% increase in span, no significant increase in bending moment and hence structural weight, and the elimination of the vertical stabiliser. I wish someone would do a feasibility study of optimising it for the transonic regime
I love it when you talk nerdy.😂
Me personally, I like the MD-11’s winglets
It is interesting that the Boeing P8 has a raked edge versus winglets.
They are even better but increase wingspan. On the P8 wingspan does not matter that much. But in many congested airports it does and Winglets are heavier but they don't add a lot to the wingspan.
It's used for it's long range capabilitie. Those P8's are used for surveillance and fly very long. Winglets are efficient on short and midhaul less efficient on long haul
Good info but the video did not address the downward tips on many winglets/sharklets.
it was possible to answer the video title's question in less 5 second "no different, just a marketing name"
speaking of airbus's winglet i think the airbus is expected and applied winglet design since 1992 on A340/A330 similar on 747-400, but on narrow body aircrafts have a special design winglets, not only in 737 and A320 also have a similar design on Embraer E-jets and Bombardier CRJs
Airbus also had wingtip fences on their A310’s in the late 1980’s too. Which also found its way onto the A320-200 (the A320-100 didn’t have them) and also the A300-600 and A380.
How important were winglets on the B747-400?? They are on the Configuration Deviation List (CDL). The aircraft is serviceable for flight if the winglet is removed and there is no damage to the wing.
Theoretically if you flat the winglets out it'll do better, just think the long thin wing on glider (or sugar). But it'll add more wingspan and more stress in the root structure.
Well, raked wingtip it's basically what that it.
Another advantage of winglets is that airport fees are based on aircraft size, which in turn is based on wingspan, so bending the wing instead of flattening it reduces the fees.
Interesting how Boeing is named as the first to install an anti-vortex solution. Airbust had them long before.... Small but both up and down on the A310, A320 and later versions of the A300.
Other wingtip devices were common om civil and military aircraft before that😂
@@jouniairplanevideos But not on commercial airliners.
I think that Boeing's winglets on the 737 have a great design, it looks really good.
It actually was design to be look good, but later found to actually have aerodynamic benefit.
@@umi3017 efficiency is everything for the airline industry. You think they'll put extra weight on the plane just to look cool?
It’s not about looks.
@@meikhochakre3309 It's originally designed for BBJ, so technically not airline industry, and looking cool is big part of prestige.
@@umi3017 I would assume that only applies to interior design.
Imagine taking a 737 from the 1980s and being able to modify it to be able to run the latest engines and retrofitting modern winglets. I wonder what the speed and performance differences of the before and after would be.
I'm pretty sure the 737 MAX aircraft are the result of doing exactly this.
Boeing already did that and it killed people...
You can't just add new engines to any aircraft. It has to be tested. The 737 program is dead. The MAX will be the final generation for it. The 737 was always lower to the ground with stubby landing gear. There isn't enough room for larger engines without heavy modifications being made. The A320 family always had taller landing gear that was stored inside the body of the aircraft. Because of this adding new engines was easy. Boeing couldn't do that so they moved the engine up by making the pylon shorter. Sure the new engine 'fit' but at certain angles and conditions it effectively ruined the lift of a significant portion of the wing.
Check out the Spiroid Winglet technology tested on Gulfstream & Falcon corporate jets
My favorite is the 737 max winglets
MD-11 winglets was a head of time.
The difference is Airbus didn't want to get sued after Boeing introduced the Winglets. So they had to come up with something different.
Which is explained in the video.
Thanks. Saved me 9 minutes from hearing things familiar to me all over again
Israel's "Arava" had winglets back in the 1970s, and was one of the first, if not 'the', to show this feature.
But isn't a key part of patent law, that you cannot patent a physical property that is required to achieve a specific function that is not achievable othervise?
Don’t know why they have them but they’re cute af and all planes should have little shark fins 😊
I always thought that the 1st winglets were on a Learjet.55 longhorn.
It was the 28 model in 1977. That wing then went on the 35 model (now called the 31). When the 55 model was designed they used the same Longhorn wing.
@@Pilot604 OK, thanks.
The pronunciation of AWIATOR sounds like a toddler trying to say AVIATOR
There is a big difference between the winglets on the 737 MAX and all other airplanes in that on the MAX the airflow is fully laminar resulting in a large drag reduction.
Sharklets
"The Airbus A310-300 was the first airliner with wingtip fences in 1985" according to wikipedia
Weird to have a video about Winglets / Sharklets and not mention that Airbus had been using Wingtip Fences for 16 years before Boeing installed a wingtip device on a short or medium haul aircraft
Airbus doesn't have that title. There are a view examples of aircraft wich has wingtip devices like boostertips. A10, Cessna 172 etc , crop hoppers etc. Designs from several wingtips and winglets already excist back in fifties. Technical possibility started decades later
@@jouniairplanevideos the quote does say "airliner" 😀
In the Boeing side, i flown a 737NG with winglets 4 times but in Airbus, i only flown with sharklets once with an Airbus A320ceo
Why the Airbus a320s sharklet s thinner than the b737s sharklet?
Boeing acts as if they themselves didn't get the technology from NASA as a free handout...
It’s called collaboration. Unless airbus wants to collaborate with Boeing?
@@OneDicz Dude, they are both Americans and working together since Apollo Programs.. Airbus can collaborate also from ESA if they want ...

Your information is incorrect. Learjet was the first manufacturer to install winglets on their "Longhorn" wing design first installed on the model 28 in 1977 (a 25 model with the new wing). The results were good enough that the new wing was then installed on the existing tip-tank 35 model creating the 31 and since has been on every Learjet, Challenger, Global and even the company designed C-Series (Airbus A-220) model. Learjet was the manufacturer that first initiated talks with NACA to explore the wingtip vortices and the wingtip design they had developed on the "Lifting-body" vehicle they were testing prior to the space shuttle. Your saying Gulfstream was the first was wrong. Learjet had winglets long before anyone else had considered the design and was the first aircraft manufacturer to use them in production.
Lear Jet introduced wing lets in 1977.
Parasite drag is produced by VERTICAL surfaces and Induced drag is created by HORIZONTAL surfaces, for example when the Flaps are at 0 degrees they produce Max Induced drag and Min Parasite drag, at 90 degrees Min Induced and Max Parasite drag and at 45 degrees in the middle of both, for a flap with no thickness. The fact that Lift and drag are both proportional to airspeed squared, means airspeed affects a 2 Dimensional surface, geometrically a Square plane. Wing Vortices are not the cause of Induced Drag but it is just a Visible Effect of it. I have developed a hypothesis to explain physical, atomic and subatomic (gravitational movements, Center of Gravity and Mass), however I need to validate my V & H surfaces theory first.
It seems that Winglets reduce Lift and increase Drag, I also believe in turbance Winglets impose additional stress to wings and all other moving parts inside the wings like rods, joints and moving surfaces. Wingtips also decrease the stability and controllability in turbulent air. Simply put another british scam.
Please let me know what you think, thanks.
Scimitars all day.. loved when united had there whole fleet changed
So, why do we not see some kind of winglet or more aerodynamic designs on aircraft elevators?
You mean horizontal stabilizers. Elevators are the part on it that acts like a flap. Any way, the horizontal stabilizers generally do not produce lift so no pressure difference to cause drag from a vortex
Airbus started using it since the A300-600
Hmm, what about wingtips on A320ceo, A380ceo and A330ceo?
The split scimitar
This article has some contradictions from an article you featured previously.

The winglets and sharklets has some differences. Lights are split on the sharklets while Boeing has all Lights together
Baby Shark! Do do do
Just the tip.
Just for a minute.
Just to see how it performs.
At least I know what they are now
All are still called winglets at the end of thr day
That was 3 years before the 747
F1 cars have winglets too🤷♂️
When I retrofitted winglets to my glider my wife quite unfairly in my opinion called them Wanklets
The winglets reduce drag.
I think the A350 is the best looking, but the 787 is close
Seems to be that if NASA had a hand in it, then the design shouldn't be patented by company like that. Thought everything NASA did was considered public domain?
These winglets do very little to reduce drag. Another myth is fuel consumption. They help a TINY bit. Probably not worth the cost of engineering these things though.
They appear to make enough of a difference that Ryan Air expects them to save enough fuel that it's worth spending more than $200 million to add them to their 737-800s.
I want to be a pilot and my wing lits will be like this
You're less likely to plummet to the ground in an Airbus .
There’s nothing that comes close to the 787 wings.

Zero mention of Airbus's wingfences? The 320 had them since 1987 (1984 for the A300/310, but who's counting?), yet according to this video it's as if they never existed. smh.
Airbus fans scream foul when I call them copycats. Well here's an undisputable example.
I have the urges to tell people wich part was copied everytime. Can't stop it😂
who made the first twin engine widebody? oh thats right it was airbus
@@einar8019 If we start counting firsts between Airbus and Boeing, it's not a close comparison, so, definitely the A300 was a game changer for Airbus, but Boeing firsts are long. For example, who was the first to build a widebody aircraft? Right.
@@einar8019 that's true, but they launched it a few years later as expected. Why? cause they think they were superior and everyone buy some airbus planes while it's everyting in meters, mm, cm, etc. Conclusion: no one, except from air frence. After the second developement it became what it is now. Still not the best start for twin engine widebodies as we have now... thank you ETOPS. what would've happend with that while ETOPS wasn't a thing?
As always sharklets are way 'better'
Airbus copied Boeing with winglets and just called them Sharklets.
Thats not true🤦🏾♂️
If my wife is on the plane it needs 50 on search side to help fuel efficiency to offset her massive weight
Imagine if your wife sees this!
UwU I'm an Awiator ✈️
The A350's look the nicest but the 787's make the most design sense.
Worr
This patent stuff is just absurd. You cannot patent Whitcomb's paper. You should not be able to patent the knowledge he brought to the public domain. Yes, it looks like the same design, because it basically is. Thats aerodynamics and they knew it, it was simply a cut-throat business move. Boeing should be ashamed of themselves.
What's a "PAY-tent?" I know what a 'PAA-tent' is, but not the former. It's a SHORT 'A', not a long 'A'. Sorry, couldn't help myself. 😉✌️
