What I find especially amazing about this setup is that these linkages allow the very complicated synchronization of each component of the flaps to be done with just a single actuator.

What beautiful mechanism! As a kid I've always wondered how fowler flaps extend in and out. Thanks to this video now I have full understanding.

Very reliable, I played the video for a half million times, they are still working!

To say the least, I really love these flaps! Excellent illustration without voice-chatter...thank you.

Fowler flaps are amazing. Very complicated design. Studied this in engineering. All Boeing 737, 727s use this. The idea is not to drop the flaps down in one piece like a Cessna. But three different flaps in sequence. That still allows airflow to get threw each gap. Each flap is designed like a wing. Air flows between each flap. Thus reducing drag and creating lift

That is truly a work of art. It reminds me of some of the complicated linkage setups that BMW and Mercedes have for their roof retraction that folds into the trunk. Engineers are awesome.

Excellent video. I've been a computer animation artist for twenty-five years. I do freelance visualization of new products or mechanical inventions as well as architectural visualization (who else could appreciate the complicated study and work you put into this video). My Boeing 757 model was used in a feature film in 2008. My rigged model was purchased from a 3D model site by a CG artist in the film production team and used in the film for which I got a film credit. I found your video because I was looking to improve my model package by making my rigging more complete. I needed to know more about the motion paths of the flaps themselves, not necessarily the mechanical linkages to them -- I can fake the linkages for such a model but it's totally fascinating to see an accurate representation of all the components and their movements. Thanks for your incredibly hard work.

Very good video. I've seen other videos that show all the movement from an outside perspective, but seeing this demonstration of the internal mechanism at work is more interesting. Fascinating stuff, good work. 👍

The flaps are just assumed to be used in take off and landings, amazing in their design and function... A piece of engineering art.

1 motor to run a 14 bar linkage. awesome to see this work.

Rube Goldberg would be proud of this wonderful and detailed animation

Long may we remember Fowler! Would love to see a set of massive triple-slotters as worn by our mate the B747 ;-)

Perfect speed to easily follow the moving parts, Excellent video!

That is some sophisticated linkage right here

It can get more complex than this--the B737 Classics have not just a main flap and aft flap, but also a fore flap that extends forward from the main flap. There are two of these triple sections on each wing, for a total of twelve moving surfaces. And then there are the leading edge devices--flaps and slats coordinated with the trailing edge flaps shown here. Plus the hydraulics, drive motors, position indicators, and protection systems. Low landing speeds from high speed wings do not come cheaply.

Excellent video. Great piece of mechanics.

This is used on the Boeing 767 and 777.

Whoever invented those flaps is a genius. 😎😎😎😎👌🏻👌🏻👌🏻👌🏻👍🏻👍🏻👍🏻👍🏻

I wonder how do this mechanism can hold the wind force in such hi speed, in thousand landing and take off cycle in every condition (clear, rain, snow, etc)? Such an engineering art

👍thanks 👍 I know the mechanics of flaps now

A toast to Mr. Fowler !! Here Here !!

Very similar to the Cessna 404 fowler flaps , believe it or not.

That's a very complicated linkage but its ingenious and works like a dream!

機体を支える強度がすごい

I am not a pilot but I love aviation. I enjoy learning it. I play flight simulator too. I really don't understand the purpose ( if not the reason ) of disliking this video.I guess it's the " how-did - I -end-up-here syndrome "

Excellent video thank you very much. Can we have the same one for the leading edges, please?

A primeira vez que eu vi este tipo de flaps foi num lockeed Lodestar, há muito tempo. The first time i saw the Flower flaps was a long time ago in the Lockeed Lodestar.

Oh that is so cool.

Muy buen dibujo, muy buena dinamica! Gracias!

I'll stick with the C-17, thank you!

Now that's some serious geometry...

Clever Mr./Ms./Dr./ Prof./ Rev. Fowler.

Always fascinated by the mechanical engineering involved in coming up with these mechanisms. I want to know how it is calculated i.e. for x motion I need y linkage.

Imagine being the guy told to go out and design this for an aircraft. 😲

Great video though imho it'd be even better if you included graphics of the airflow so viewers not in the know can see what the purpose of Fowler flaps is?

Really excellent video. Better would be to put in the sound that flaps make while in operation, e.g. in the workshop.

With triple trailing edge Fowler Flaps , each with a flow director, together with outboard Handley Page Leading Edge Slats, & L.E. Inboard Kruger Flaps, The Boeing 727-100 & 200 Series win the 'Flap Parade' & in a big way.

Woowwwwwww!! ¿Todo eso pasa cuando se bajan los flaps? Excelente video.

I love them, hence my screename

these flaps belong to the triple 7

Ok for how it move, but we need to know how it work with the aerodynamic too

Seems so fragile. All these moving parts just for moving a piece of wing?

I love Fowler flaps as that is my surname.

thank you for video

It is my big question when I take plane, today I get the answer.

Please have mercy on us peasants

Excellent never before it was so realastic pls arrange 3D plane crash investigation

i like it

Es ist mir ein Rätsel wie diese filigrane Mechanik die enormen Kräfte der Lüftströmung standhalten kann. Diese Flaps erhöhen ja nicht nur die Tragfähigkeit des Flügel sondern verringern auch noch durch mehr Luftwiderstand die Gleitgeschwindigkeit. Darum werden die Flaps und die Vorflügel für eine höchstmögliche Reisegeschwindigkeit wieder eingefahren weil die Strömung schneller wird und damit für den Auftrieb reicht. Aber wie das ganze hält (insbesondere bei einem Cargo Jumbo) kann ich nicht nachvollziehen.

asombroso mecanismo.

What makes this a Fowler flap and not just a flap? Is it the bottom hinged part of the flap? I can see how hinging it like that allows it to be more curved but I could still think of the whole assembly as one flap

Thanks

What’s the difference between Fowler and slotted? I don’t understand the difference

Güzel icerik tebrikler

reminds me of bird wings

Does someone know how to dimension the mechanism in order to achieve the movement desired?

Nossa muito loco, o professor Juju manda bem mesmo em, UTFPR-LD é muito loco !!!

Verylike ....

very nice video

excellent video :)

Flaps, hehe, funny. Flaps that fowl as well. Splendid work but it’s The fish! O its the fish I was actually looking for the painter but as I've eaten a vast quantity of this fish over the years its only right that I enjoy your video. MMMMM flan, theres nothing finer than a good flan, well maybe theres cheese cake too? I wonder can you combine them? That would be an interesting experience I think also I do enjoy memes but why would you play a game for 2 weeks? It’s a tough one however if you have nothing else in your life.... anyway It’s been a while but this reminds me about the tragedy & of the importance of listening to First Nations people’s who have a lot more about them but Condensing the whole world into 19 minutes is a fascinating experiment & your presentation style is very entertaining as well as informative although I’ve never knowingly eaten steamed hams & if I did I’d just like to know about it first, maybe they could use Advertising is a very intriguing game & Pronunciation is a very unique thing, It’s interesting, we see the tank aim, fire etc but at what? We only get a tiny perspective on what’s actually going on. With that in mind Fascinating to see the inside of the machine in this way however have you ever wondered about the consequences of Spraying stuff into the air has been going on for many years and this is Huge! That’s what this is, but LGR has, to my mind, a fantastic voice, like me but This is fascinating indeed, when I was growing up and even now Twonk was & is a lighthearted insult, but you’ve taken it & created an alien collection of sound which whilst It’s good to see these little hidden gems that stop you being tired & deflated because it is terrible. I mean you try to keep your chin up & then it starts to blow up. You see it’s the leopard not the panther that makes sense. But then does making sense really mean everything it’s meant too, Ben! Legend. But Ben is not alone there are loads out there You see! Snow! We love the stuff don’t we? I think I’ve caused someone some consternation this morning. Before the moon set today & the sun took over I posted to social media about the river in that runs through my town was higher than normal, which it is, however the lion doesn’t really appreciate the help of a leopard when they get across the grande. I’d bobble my own head but funds being as they are I can’t afford to get a personalised version of myself What? What is going on? I don’t know but Bruce knows ask him! But When a car travels it too has to compete with the fluid we live in but it’s very easy to be an idiot & it’s easy to be careful too. It’s easy because all you have to do is concentrate on But I find water a real drag, haha, fluid dynamics are complex & simple simultaneously I mean it’s something that we all deal with constantly but just how much do we actually understand Products. To produce is a real skill but it consumes too. So you simultaneously create & destroy Sharks? Sharks are blunt nosed idiot eating machines that spend their time wasting it. When the challenge gets better then you can get it to be a better way of keeping your brain going. When I see kids running around blasting music and it’s hate all over the place I don’t want them to be like that & ruin their lives. When I do that I dint get the same result. Here’s the thing about that, we are individuals with our own experiences and If hair was currency then I’d be so poor you would respect my ability even open my eyes and gaze upon your vizog I haven’t got a square head so why depict me with one? That’s a tad rude. But and it’s a bit one, I’ve gotten to see that if I’d planned it you can bet I’d have spent all my time traveling Crosses & all that wooden stuff nailed together can be very very disturbing to the unarmed people that bolt when I’m on the train I’ll just take ya to the second degree and then let’s get together and get some stuff together I can do something else to make sure I’m doing it right. When I want to get angry I’d see you there and then I’ll be happy with ya. It’s such a lovely day today. The weather isn’t brilliant but it’s not crap and that is what is important. To say that I watch you would be a, well an untruth. I hate untruths they get everywhere & hang around the place making it look drab & boring so If I didn’t know it already then I’m not going to learn it now am I? So there I go typing that word again and I find out that it’s you! Wow! Love it lol, With that in mind, and I’ve got to admit I agree with you totally, blyat. I’m squatting right now in your honour. Dear lady you spend so much time on this that you will get your life together soon and then I’ll be happy. Those late 90s styled fonts are such a retro touch. Thank you & for goodness sake you have got to go out to dinner and then I’ll be back in the town soon. Again I typed the word expecting to see nothing, and here you are, When a person spends time in the sun with friends it’s always a pleasure being there. When the people who have been received in the waiting room they spend a fair bit of time on their phones this can cause others to grumble. I hope that you can understand how much more of the money will be made in data transfer costs, with that in mind, the leopard in winter is great.

hola, esta animación esta disponibles con sus dimensiones ?

Greetings +rexxxtube. May I use this video for educational purposes?

thanks bud :)

Show projeto expetacular.

Someone has kinematic analysis of this?

quanto a pressao do vento.

cool

관절이 너무 많이 그려졌네요 지금은 모두 하이드러로 동작되어 보다 간단하게 플랩이 동작합니다

👍👍

I understand you won't share your files, any chance you can help me with some references that you used to get your design. Thank you.

IKt would have been cooler to simply animate the slotted fowlers on the Boeing 727 and 737 series

The mechanics look like someone doing the most insane pull-ups

개구리의 도약

Very strange music

What gives the initial movement to this?

could I get the bars dimentions please?

does anyone here have the patent number or the design name of this fowler flaps? please inform me, thx

aka inboard aileron/flaperon

Проверь нагрузки в solidworks

Do you sells?

Ok. Flaps come out and retract. So what?

It’s sooo hot!❤️

You can thank the fine folks at Lockheed for the development .

where can I find the file for this animation?

Cool music also: what is its title ?

Similar to a 777's flaps

Is this the case of boeing 777 ?

Does this apply to 747's too?

767 flaps?

Isn't how my wifes flaps work

Rubbish soundtrack

2 minutes and 9 seconds and not a single word is spoken - what a complete waste of time.
