I could never visualize all previous verbal explanations of how this worked. Your animation is awesome. It's now perfectly clear. Thank you.

This is the best animation I've ever come across related to mechanisms/how stuff works ! Really great job ! Very well done ! I absolutely loved it !

Oh wow, thank you! Now I finally understand cyclic pitch control. Previously I thought there was a mechanism that individually flipped the blades two times per full revolution. But the clever engineering of the swashplate doesn't need to involve this.

Simply amazing! This is a great reference to anyone who is learning to fly helicopters. Thank you very much!

Thanks for posting this, it makes the dynamic control of the rotor pitch very clear.

Thanks. As an R22 pilot, and coming from the fixed wing world, I had to wrap my brain around the fact that the angle of attack is different depending on where the blade is, as it rotates 360 degrees.

I had the S61 course at the factory in 1964. Spent 4 years on HS 50, 4 years VX 10 and 4 years teaching Sea King in the RCN. My understanding of blade movements was that for forward flight, the blades on the right side had the advantage of airspeed and developed more lift. They needed less pitch and lagged a bit. The blades on the left had less lift due to reverse airspeed, they needed more pitch to keep lift balanced. They tended to speed up and lead. The lead and lag of blades was controlled by the dampers. The same dampers were used to position the blades to put # 1 blade over the tail for blade fold. I am 88 now and rustier than the Sea King. I hope my theory of helicopter blade action is still accurate.

What an incredible animation! It really helps to understand pitch and swashplate movement. Thanks

The best animation that was ever done!

Thank you Karel. Beautifully presented animations.

So that's how it works! :D Thank you for the animation Karel :)

Thank you, I was trying to picture this in my head, but this is 1,000,000,000 times better.

Its GENIAL.... Perfetc movie. Now Im undertood!

Wow, this is awesome. It helped me with an assignment I have. Its an ingenious system.

Great video showing how the rotor head works. This is a great teaching tool.

Thank you, i finally got it how the helicopter works with your animation help. Very nice job!

This is a very good representation of the rotor head and excellent for learning how swashplates and pitch control rods work. The only minor discrepancy is that the inner blue portion of the swashplate is actually part of the stationary swashplate and therefore doesn't rotate. It is separated from the (outer) rotating swashplate by a pair of ball bearings. Nevertheless, brilliant video!

Oh that is cool. It's worth watching because camera 2 switches to the perspective of being mounted on the rotating portion of the assemply so yes, the green box "looks like" it's rotating. This gives you a great view of the actual simplicity of the action. In this view the swash plate wobbles, actuating the control rods for cyclic action. OK, I'm not describing it perfectily but I really appreciate what you've done here.

Lovelly this video. It perfectly demonstrates the movement and dynaminc of the blades and rotor head. Perfect!!

i swear this is the best animation to get the idea of design . thankyou author

If you ever wanted to know how a helicopter flies and generates directional lift, watch this video. It is extremely well done, however, it assumes that you have a basic understand of the physics of lift and the engineering surrounding the rotor head itself. Personally, at my level, it was GREAT. Very informative.

Very Nice ! Thanks !

Hi, thanks for your reaction. You're fully right about the main mast and it is also animated like this. The reason why you think it is steady or rotating is because I've put in some lights into the scene which are static in relation to the gearbox (green part). If you rotate around the gearbox you have the impression that the mast is rotating (lights in the mirror effect). If you keep it steady in relation to the lights (gearbox) then you might think the mast is not moving, but it is indeed.

こんな構造考えて現実化した人間は素晴らしい！

Thanx a lot, this was quiet easy to wrap my brain around!! :-D I especially liked the different cameraes, so I could get the complete picture!

very interesting. the slow motion really helps in understanding the concept of how it all works.

wow, quiet impressive!

Thanks to this video, I finally understood todays class. Thank you and kudos!

This is a great teaching aid. Thank you!

so simple yet so genius!

That is beautiful. Thank you.

Thank you very much my friend! This is very helpful for me because I'll be sitting exams soon to be a pilot in the French Air Force!

Simple and nice! Thank you!

Extremely well done. Thank you for posting this.

Davvero ben fatto! Complimenti e grazie. Finalmente ho capito come fa a muoversi l’elicottero. Dovevo arrivare a settanta anni. Meglio tardi che mai.

Awesome animation.

Thank you for sharing this!

You're fully right. The faster the helicopter moves the faster (relative speed) the right rotorblades move and the left rotor blade (for a counterclock turning rotor seen from above) starts to stall from the inside to the outside. At a certain high speed the right side meets the sound of speed and the left side stalls. That is the reason why helicopters can't fly very fast. Couteracting this effect is done by increasing the angle on the left blades and decreasing the angle on the right side.

Brilliant vid... now I finally understand how a swashplate works... thanks...

Perfecto. Now I fully understand. 10/10 great video

its good animation for a basic general idea thumbs up

Fantastica animazione 3d x comprendere il passo collettivo e ciclico.

after a 20 years .. finally i know how's this thing works

Very Cool!

pretty kool animation

Awesome... Thank you!

Excellent Sir !! Very thanks ..

This problem is solved by installing flapping blades (they can move up and down around a hinge or a flexible part close to the rotorhead. The forward moving blade has a higher speed and produces more lift moving the blade up, thus reducing the angle of attack and the lift. For the backward moving blade the opposite happens so the lift increases on the retreating side because the blade moves down and increases the angle of attack.

ya i agree with the other posts. it looks like ya took your time and did it right. its videos like this that satisfy my curiosity about nerdy stuff like this thanks

Excellent you make it so easier to understand!!

UNBELIEVABLE !!! Great MASTERWORK. GREAAAAAT. PERFECT. WONDERFUL. YOU ARE AN ARTIST. VERY PRECISE

I was having some trouble to understant how the cyclic part of the main rotor, with your clip is now clear as water for me. Thanks =)

To my knowledge the system is mirrored. The rear blade doesn't have the folding system. Because this blade hasn't the bladefold system, a counterweight is attached on the other side of the rotorhead to oppose this extra weight.

Amazing video. Thanks for a job, well done!

thank for you posting ,don't forget more

Thank you for your work, The first time I understand how helicopter works and how 3d flight is possible.

Now I understand the swash plate mechanics.Thanks.

3dmax rules!!! heel vet gedaan

Thanks so much, It's very clear !

Wow... Thanks for the video.

Great, thanks

Now I can craft my own home made heli, thx :D

Oh wow that's great bra,thanks a lot,after this corona thing I'm starting my project.And i show you it

As Daredevil Dan once told me Man Was Meant to fly but it is a Miracle to HOVER.

Very very nice. THANKS

Thank you very much, i need to build this system for my class, now i understand it better.

Good work! Thanx!

very clear animation. Best reguards from germany

Gyro preccesion is real real mysterious force of nature I still cannot comprehend it exactly and truly how it works in a helicopter

Fantastic

absolutely gem of a video animation keep it up...!!!!

amazing

Awesome video, could never explain this to someone in words; most people can't sit still that long. Next time I'm asked about this principle, I'll send them to you.

Ja Fozzy, dat heb je mooi gedaan.

Amazing!!!

Awesome

Хоть одно годное видео нашёл 👍

Awesome, 5 stars :) This is a pretty simple rotor head. Have you done one of these with a bell-hiller head? I have a hell of a time explaining that one to people :)

Great amination. I see Sea King rotorheads all the time as I clean them. If only they were'nt as complex as they actually are.

Lesson 4 dampers are there to reduce the possible outcome of ground effect vibrations in the hull. It can cause damage or even a crash. In the AH-64 you'll see two dampers per blade ..beautiful.

nice vid now I actually understand how it works, should help for my air tech exam next week :).

Great 3d animation. Subscried

I never understood how the swatch plate could be connected to the shaft and tip in all directions. Watching this video I can see that it is a simple ball on the shaft that allows it to tilt. Great video, it is stuff like this that makes having the internet pay for its self.

Great video!

Que invento tan ingenioso y a la vez tan simple.

Pekná názorná ukážka

Best video showing how the swashplate works.

Everything makes much more sense now! Also, that is a lot of moving parts.

Sensacional!!!!!

A LOT going on there. Every part is so critical. No short cuts on the preflight check list.

Круто! Очень наглядно! Спасибо! :) Cool! Very clearly! Thanks :)

Good vid. Many Sikorsky's have a similar design.When I first got into aviation I was trained and flew on the old HH-52A's. Had a little time fixing and flying on HH-60's. Fixed and flew mostly on the HH-65's. I did alot of MRH work over the years. Too bad we didn't have this vid when I started in aviation way back when.

en este video-animacion SI que se ve perfectamente la funcion del colectivo y del ciclico. gracias por el video.

This animation is fantastic Fozzy, Cheers. It perfectly shows all the various sections working during various Cyclic & Collective manipulations. Bloody well done. Any more on the way?

lol like a merry-go-round. i thought heli heads were the most complicated things in the world until i started rc and got me sum helis, and its actually so simple :P

good work compinche

Nice!

good!

Thank you for ur show...

Brilliant video! I leant more in 5 minutes than watching countless other "explanatory" videos. Well done! +1
