Helicopter Control
Вставка

- A video showing the flapping, feathering and lead-lag motions of a helicopter rotor system.
The full video explains how these are used to control the helicopter.
Helicopter control relies on motion, or degrees of freedom, of the rotor blades. The flapping degree of freedom is essential for controlling a helicopter.
Other topics covered, in the full video, are flapping hinge offset, advancing and retreating blades, the region of reversed flow, forward flight dissymmetry of lift, retreating blade stall and rotor blowback.
As a machinist, 26 years experience specializing mainly on CNC Lathes of all types and sizes all i see here is hundreds of hours of beautiful lathe workpieces

ES FACINANTE.
Pfft, seen the african version of a helicopter?
Verdade, se nós "humanos" dedicasse nosso tempo com o que verdadeiramente importa, estaríamos mais perto de descobrir um meio de chegarmos a um planeta habitável.
Para isso temos que amar o próximo como a nós mesmos, e amar a Deus acima de tudo!

So complicated, and yet so reliable. Amazing.
👀
Reliable? This is counted in hours of use to be exchanged for new ones.

An order of magnitude less reliable than fixed wing. And when things go wrong in a helicopter, they REALLY go wrong.
Complicated but not reliable. Helicopter is least reliable aircraft.
Fabulous graphics.....some piece of engineering the helicopter rotor head!!

Ideas will come into fruition. Great job here.
I love the inclusion of the pilot's controls and seeing how it changes the movement.
Also very cool seeing the motion vector.
The rotary movements of the rotor blade is CYCLIC PITCH ! The up & down movement of changing blade angle for lift/ take off and forward/ backward movement , side turning and landing mode is COLLECTIVE PITCH ! The big handle between the leg is for cyclic pitch and the smaller handle at right side of pilot seat is Collective pitch !
The machining perfection in this things is absolutely out if this world
Awesome, really can assist many in understanding the dynamics of helicopter aerodynamics
👏👍 Molto contento di questa spiegazione, nella sua semplicità veramente esaustiva grazie a questa bellissima grafica!!
I ever worked on offshore oil rigs for 6 years and took chopper nearly 100 times. I often sat behind pilots to watch their complicated operation. Fortunately I never encountered emergency. The helicopter models were Sikorsky and Super Puma.
Great video
This sophisticated mechanism is what holds human life together.
Very important and educative, it widening my scope of what a helicopter is design upon. I appreciate if I will be carried alone on subject matter, thank you
I really like being able to learn this knowledge😊
The graphic representation is amazing. Very well done.
Thank you🙏🙏🙏 so 👍much . Useful information.... 🎉
I wonder what software could make such an interesting model and animation?
Really impresif me about helicopter component such as Blades Chopper and its rotation. Another one makes me impresif is Chinook which can lift 40 feet container etc. Amazing.
I'd love to check it out. I've always wondered how it works.
I'm not sure if I can share a link in the comments... here it is (unless youtube removes it) ua-cam.com/play/PLhRKWwg17yplNtUs1dlEnG5AUUQ5ZN6Bs.html

Yes, it worked. Thanks.
Good luck and good job
Very good
Que buen video!! Gracias por compartir!! Mis saludos cordiales de Argentina!!!
Good video 👍
You didn't mention gyroscopic precession. The input is 90 degrees out of phase with the output force.
Good comment! It's hard to decide what to put into the shorts. I cover phase delay/precession in this video... ua-cam.com/video/-8QzYicgTL8/v-deo.htmlsi=fXXwMsdgOcbJcdQP
SubhanAllah kya kahne lajawab 👍 mechanism 😮
Amazing information 😊
Learning more about this thank you so much.
Good information
It's incredible how anyone figured it all out in the first place!!!
Subscribed!
Thanks!
All the parts are like a team for Central control.😊
Interesting subject 🎉👍🙏👌
Good information 👍
Thanks for information 👍
I understand the vertical take-off. But forward or horizontal movements is what I don't understand, especially with helicopter without torbofun engine.
If you see the plate below the rotor hub - once you push the control lever forward - it basically tilts and the small 4 rods connected to the rotation of the blade ensure that the blade is slightly rotated (thus scooping more air) when it travels to the forward part of the circle - you can imagine how each blade slightly rotates along its axis during each revolution of the rotor. This can apply to all directions of the helicopter travel.
@@KeenlyJohnasese y el control de paso lo entiendo. Para qué son los otros dos movimientos?
材料和制造工艺才是关键！
Perfect 👌
😮 super animation
Amazing
This mechanism is precisionly made to perform accurately. Precision aeronatic engineering.
No mostly mills, I used to manufacture alot of those components for bell,at the last shop I worked at before I had to retire.
Awesome, I'm going to make my own helicopter
Sangat berguna bagi para pemula yang sangat ingin mempunyai helicopters buatan sendiri👍👍
Thanks
Excellent.
me gusto muchicimo la parte de transmisión el mecanismo para dar el angulo de ataque a las aspas del rotor principal y tambien se alcanza a ver el eje de transmisión y el rotor direccional
Great masterpiece 🎉
Very nice 🙂
curves to push air downwards would make bigger power
Nice❤❤
Mashallah very nice video👍👍👍👍
Amazing machine, the helicopter!
Sensacional!!
good
Did Igor actually figure all this out, or is this decades of research?
Igor was no-doubt a smart person, but he credits a lot of the basics, of the first helicopters, to the autogyro pioneers. Juan de la Cierva is generally known as the guy who came up with flapping control of the rotor.
I still can not imagine and think the logic of why the thin blade and thin frame can weigh the very heavy body of helicopter ，why ？
What's really interesting... If you grab a helicopter blade while on the ground, and static, they are pretty flexible... You could flex the tip of the blade quite a bit with just human strength.
The blade gets a tremendous amount of rigidity from the centrifugal flight loads that come when they start rotating.
@bzig4929 ,
Hi , thank you very much for your explanation.
Why are the blades rotating in reverse direction in this video 😅. It should be the opposite 😂
The swachblade
Nice 😊
Algunas piezas se ven tan endebles y sin embargo son capaces de durar horas y horas de esfuerzo.
rear propeller function ?
Alot simpler since it only controls yaw. Just a single shaft through the middle of the retention plates, they hold the tail paddles in place. The control for this is cable driven, and had an emergency lockout system that will lock the pitch of the tail rotor in place in the case a cable breaks.
Nice ❤
I love helicopter. But looking at the engine, it look so fragile and definitely no sudden move
They can use the same technology that the dysons fans use I bet, to create Lift, and silence
Notar tail rotors are similar to the Dyson fan. They also take advantage of the coanda effect from main rotor thrust over the tail boom. Lower noise is one of the reasons they came up with them.
❤️❤️❤️❤️❤️ BEUTiFUL 🔥🔥🔥🔥🔥
Это шутка? Две лопасти из четырёх можно использовать для движений в определённую сторону ????
It's correct... The reason you only see two of four blades moving is because I show them positioned, in azimuth, exactly at the phase offset of the rotor system. If they were 45 degrees from this position, all four blades would move. It's a very good observation. I should make a video to clarify this. Thanks for the comment.
If you roll right or something, does the prop pitch change as it rotates or does it stay the same?
Rolling the aircraft to the right requires a blade pitch increase at the 12 o'clock position, and a pitch decrese at 6 o'clock. In the long form vid, I show an example of a left turn.
Who's ever invented I give theme a saluted 🫡
Ohhhhh, Now I know why mine isn't flying. Thanks.
Good Valo legeche
This is the secret that was lacking African made helicopter to fly.
From Cameroon.
Un ingeniero sabe como funcionan los aviones... pero solo dios sabe como vuelan los helicópteros..
I understand the sentiment. Maybe airplanes are easier for the human mind to understand, but our knowledge of any complex system, airplanes or helicopters, is imperfect.
Very good j🙏❤️💐👍
Q mecanismo fantastico q fas um equipamento muito util
Nice

Очень приятно наглядно и понятно...
I didn't know it was that complex and complicared. 😢
nice
How did you get your license , well … on UA-cam from 1 min short video
Excelent!
And what's the used of tail fan?
it counters the torque of the main rotor. The helicopter would spin, opposite main rotor rotation, without it.
It flies by the grace of God to show you some of His signs. Indeed in that are signs for a people who reason 🕊️
Chia sẻ cũng tuyệt vời ❤🎉
Looks like a black hawk drive train
Yes! I did a series on how I came up with all the gear ratios and locations ... It's all based on public source data on the Blackhawk.
Perfect

More videos like this please tanks so much 🫡👌👍👍👍👍
That's good
Remember Discovery
Now I need practical training😊
Good
Nice friend i
ECR will soon take over , we will have to do away with the swashplate mechanism and just include a trailing edge flap to the rotor blade for directional control
Agree, except for the word "soon". But tell me I'm wrong... Has anyone done significant full scale flight test of electronically controlled rotors?
@@bzig4929 Yeah soon was not a right choice of word, sir. And about flight test, not that I know of has done it. Still has a long way. My team has just done, small scale flight tests. still a long way to go
That's cool. I envy you working on cutting edge stuff like that. More than just the swashplate less design....higher harmonic and individual blade control has the potential for fast and smooth rotorcraft.
@@bzig4929 Yeah sir. Btw, your channel is very educational keep them videos coming brother. Stay safe out there and happy new year
❤good good💯💯
Fantástic.
