I have 40 plus years of working on Jet Airliners.Started working life on B707, then B727, B737, B747, B757, B777, A310, A320, A330, A340, DC 8, DC 10. Have worked on D checks, C checks, Line Checks. Specialized in Airframes and Engines, with working knowledge of almost all the other systems on the planes In D Checks, aka Depot checks, we remove the engines, flaps, flap fairings, body fairings, slats, landing gears, cabin and cockpit seats, galleys, toilets, floor panels, ceiling panels, ....you get the picture; by the time we were ready to carry out inspections, she looked real naked! However, I have Never seen any Jet Airliner with flaps that work as shown here. The Closest I can think of is the DC 10, in the sense that it did not use motors and torque tubes. Even then what is shown here is totally alien to me. I have seen a couple of other videos about aircraft on this channel, and I get the impression they did not even consult any technical manuals and just dreamed it all up.
I believe these are "Fowler Flaps" they extend and rotate downwards when actuated. Flaps don't have to extend, but it gives more wing area and more lift, and are more effective than a simple flap that just rotates into position.
You failed to mention an important feature, as well as providing an aerodynamic fairing for the flap tracks, they are also used as Anti-shock bodies or Whitcomb bodies and reduce wave drag at transonic speeds between Mach 0.8-1.0 using the Whitcomb area rule
LE, you should do a video on Vortex Generators and leading edge technology such as slats and slots and how they contribute to lift. I thought most flaps are fowler flaps and operate via jack-screw.
Thank you for uploading a video like this!!! It's useful for especially for someone who really loves airplane and has been wondering how everything works!!!
Thanks for a great video, just out of curiosity: what kind of machine they have to move that green little thing? Just a normal electric motor? And does it require lots of power to move that? And lastly, would the flaps be deployed if that thing broke? (Due air flow to the pocket that moving the flaps makes?) Thank you in advance! :)
How about do away with this protruding thing at all by adopting somewhat old technology - double deck wing. I mean two wings or four major wings on commercial airplanes which would consume less fuel. Double stacked wings can generate breaking more with additional flaps between, upon landing, and simple control mechanisms can take those functions, which means airplane has to fly at slower but at efficient speed. Or they don't have to be stacked on one another but upper wing could be positioned a bit forward and at less aggressive angle just to give the bottom wing higher air pressure.
For me it was easy, though i dont know if the idea i have applied is correct. But i will try to give explanation: if we consider example of a hinged door regarding torque concept then perpendicular force applied on a hinged door is less and its speed of moving the door is high , when the contact point on the door is far away from the hinge but the more closer you get towards the hinge side of the door, then the force has to be increased still the speed gets slow and the door will move(rotate) slowly but with more force. Same is the condition here, the point moving at high speed is away from the joint(hinges in a door) so less force but high speed and vice-versa for another point.
tangential velocity vt = omega (angular veloccity) x radius radius for the light green one is bigger and they both have the same omega therefore light green one velocity is higher
+roller321321 It is so close to true. Had flight during xmas. Anouncement on the plane stated: "during lift off all mobile devices must be switched to flight mode. All Samsung 7 devices must be switched off all the time"...
Dear friends, we re-uploaded yesterday's video with few improvements. Thank you !
Can you next make a video about the fake of the bedini?
Ohh, this is a new information for me. I will check it out. Thanks
:)
Can you tell me how does contra rotating propellers works?
Learn Engineering why there isn't translated Arabic?
Fantastic animation, makes a complicated mechanism so easy to understand! Thank you so much!
Nice and lucid explanation. But the linkages should be designed to withstand the enormous wind force on the flaps while generating lift
it's basic kinematics simply genius.
Excellent, I haven't no words to tell about, for your way of explaining/teaching.🙏

Muy instructivo. Me vendra de perlas para explicar mi asignatura en el IES

Amazing video."Another application of 4 bar mechanism, wow"
Great explanation, thank you
please continue uploading these videos I'm learning a lot with them and thank you!
Awesome and helpful channel! What software do you use to create those animations?
Nice educative video Thanks !!
Very thanks for this charity
The covers also act as lightning arrestors.
Good explained
Thank you for uploading a video like this!!! It's useful for especially for someone who really loves airplane and has been wondering how everything works!!!
thats a great looking airplane not gonna lie.
Thanks For Sharing Beautiful Explanation. . But there are Some More Reason what this do. .
kindly upload more videos about airplanes. Just like airspeed indicators working. Heating system.
Thank You
Thanks a lot. 🙏🏽
Housing for the giant screwjacks often referred to as "canoes".
v1... rotate
That looks super stressful on the crank
well clearly it doesnt stress it to the point where it breaks otherwise they wouldnt do it this way
eyyyyyy we have the same profile picture!
No, never wondered about it.
Explain the Turbulence please.

Good afternoon sir please I use a clip from the video please sir Please don't give copyright ©️ you give already copyright I give your RUclips and your business link in description please.
I have been thinking about this since my last flight
I believe the shape of it also helps to dissipate sonic booms.
10/10 landing

I really like this but can you show me how Stirling engine works
They are also called 'canoes' because that's what they look like when they are taken off
Yes! The term 'Canoe Fairing/s' is commonly heard...
What program do you use for creating the models and animation? Thanks.
I get a boeing ads before this video starts XDDDD
Xx_Minecraft -Professional_xXx RUclips might use cookies to track what you watch and put a relevant or semi-relevant ad.
How do the elevators work and how they stabilize the aircraft?
Interesting
Please discuss the motion of f16 landing gear
can you please make a video on 'why does a spinning top not topple'
Cool where can i buy one?
I always wondered what this chubby things are... THANKS!
Flap track fairings
which software did you use to create these videos
Why don't plane designers put golf ball dimples on aircrafts to increase the efficiency?
I'd like to know how to predict the position of the limbs. Thanks
wasn't this uploaded yesterday as well?
Some slight improvement :)
Alright, that makes sense. I loved the one from yesterday though
I recognize the voice of he robot. It's the same one used at Disneyworld.
These are known as fairings.
can we get information of wingtip vertex
So why is it not flush with the end if the flaps?
Why was the reposted?
We removed few spelling mistakes and added few more information to the old video. :)
Learn Engineering Just a suggestion but you might update the title with something like "Take Two". BTW I enjoy your channel.
'Take Two' usage may confuse most of our viewers. Anyway thank you for your suggestions.
there wan a screw mechanism instead of this mechanism in the vedio I believe
I thought it also functions as a additional fuel tank ?
Fuel tanks are usually placed within the wing volume. You may be confused with drop tanks which have a similar shape for aerodynamic reasons.
it's not rocket science to understand that they are just cowlings
thanks for video, but it is not so obvious, that light green part moves faster then dark blue part
For me it was easy, though i dont know if the idea i have applied is correct. But i will try to give explanation:
if we consider example of a hinged door regarding torque concept then perpendicular force applied on a hinged door is less and its speed of moving the door is high , when the contact point on the door is far away from the hinge but the more closer you get towards the hinge side of the door, then the force has to be increased still the speed gets slow and the door will move(rotate) slowly but with more force.

tangential velocity vt = omega (angular veloccity) x radius
radius for the light green one is bigger and they both have the same omega therefore light green one velocity is higher
why was it reposted?
Yes, we added few more information and remove some typos :)
More like basic grammar error in the title :)
Learn Engineering hi
Anti shock wave bodies
Why not just direct drive actuators attached to the inner end of the flaps?
Linear actuators a shit
s50201 To counter drag forces. It would be hard to activate at high speeds
Jo-Ann Li Seems like a lot torque would be required to actuate that little link as well though. I guess it's a "do the math" situation.
s50201 on airbus 320's they do use hydraulic driven linear actuators.
Did you add additionally awkward narration? It sounds like text to speech translation.
Yes, the voice-over artist narrated it in a different feel. That't why it feels awkward. :)
Why does the flap need to translate?
Increases chord length and angle of attack
How can you publish this video without even mentioning the main function of these ANTI SHOCK BODIES. not flap fairings. Wow.
Advice in the end of the film is a bit wrong. It should be: ..."Next time you board an airplane. Try to figure out who is the terrorist"...
Nemo D333 *Hint* Its the guy with the new Samsung product
+roller321321 It is so close to true. Had flight during xmas. Anouncement on the plane stated: "during lift off all mobile devices must be switched to flight mode. All Samsung 7 devices must be switched off all the time"...
