whoever created this animation is highly skilled, i think few people understand just how many very complex parameters had to be created for the frame physics alone thats forgetting the quality of the graphical skin applied over it, incredible video that gives a very clear insight into how the rotor head works
Excellent animated explanation - now if only I could make sense of it...I have one which I have rebuilt almost as many times as I have flown it - but I still do not really know what it is doing. The last time I really tried to figure it out -some thing flew apart inside my head.
Beautiful animation. Explaining further how the rotor system works, there are 3 inputs go to the main rotor. 1) Swashplate to the rotor, 2) Swashplate to the stabilizer bar, and 3) stabilizer to the rotor. The stabilizing aspects of the rotor mainly comes from 3). The stabilizing system is basically a mechanical gyro sensor with aerodynamic damping. Well, since this video was published back in 2012, all radio controlled helicopter manufacturers have moved away from such mechanical stabilizing system and moved to 3-axis electronic gyro system. The two mixers mentioned in the video have all disappeared since then.
I wouldn't go as far to say disappeared, but certainly less common. My 450 is a flybar, albeit I bought it used. However a few companies (Avant comes to mind) still make flybarred helicopters. For how much longer, is anyones guess...
They still use flybars in industrial machines like the Yamaha Rmax and it's successor the Fazer (which came out in 2016). This is because a flybar is head referenced rather than airframe referenced and because it's completely mechanical there is no control loop delay (in a flybarless system the airframe most move before the sensors detect it, then an appropriate response is calculated and implemented by the servos and then the airframe must move before the sensors detect the change, and this loop repeats). In the case of the Rmax and Fazer, there is an electronic stability system similar to a flybarless controller in *addition* to the flybar. By doing this they get an exceptionally stable platform that has the advantages of both mechanical and electronic stability.
Still excellent. These should be used in colleges and aviation schools. This should also be on display at hobby shops as this is a popular entry method of flight control.
Very well done congrat. The only thing I figured out so far are the cyclic commands (tilt forward, back, and both sides) this is done actually 90° before the actual effect is needed to take into account gyroscopic at play. Ex if you want your rotor disk to tilt forward the blae forward should lower it's lift (i.e. reduce it's angle of attack) and the rear one should augment it's lift (raise it's angle of attack) so as to create this forward lift and motion. But actually this action would commanded by the head rotor mechanism when the blades are on the sides because the resulting effect will only be felt 90° later. Pitch mechanism is far easier to grasp.
@@nighthawk0077 in theory what about reality? looks like we still need parachutes on these machines...thanks for bringing me back to this comment 5 yrs later!
The videos of the Sikorsky rotor seem easier to understand and I think the Sikorsky system is simpler. The Bell rotor seems to have way to many moving parts.
Try turning the vid around - Hiller rotor-wing aircraft turns in a counter-clockwise direction.... I did my solo in a OH-23 back in '68 - you're screwing with my brain...
In a real chopper, your life hangs on each of these tiny linkages. If just one comes apart, the whole aircraft goes out of control and you're a gonner. It's scary.
it dose NOT show the effect of the fly bar that makes the video point less the cyclic control is done with the fly bar the fly bar is kind of controlled by the swash plate
Nice video but forgive my ignorance as I am struggling to see what it's for and Google hasn't helped! As I understand it it's some kind of servo mixer that mixes the pilots commands with commands from the teetering mini rotor, is that correct? not seen this on real helicopters so is it used today or mostly in models? what advantages does it have? also does the main rotor seesaw too, because I can't tell and it looks like it doesn't but I thought twin rotors usually do.it all looks really clever and if anyone can explain it or give me a link I would love to see your comments below.
This type of rotor system is rarely used these days since three axis gyros are now used. The flybar system is too stable for rc helicopters that want to fly extreme 3d.
its complex form of flexible joints, im afraid if anything gets stuck whilst it is hundreds of feet up above the air, just increased my fear of choppers great video nevertheless
I wouldnt worry too much. Most (all?) passenger carrying helicopters are flybarless. Model helicopters (like my T-Rex 450 SE) use this flybar style stabilization, though many (most) newer models are also flybar-less.

Good animation. But I still can't make out anything. With a conventional swashplate, everything is clear. There's nothing complicated. And here there are so many rods that it is very difficult to disassemble what pulls. Probably I will figure it out only when I myself buy a helicopter with such a scheme.

First time ever really looking at a helicopter rotor mechanism. The people who designed this thing must have been absolute geniuses.
Agreed. I even think model rc helicopters are even more complicated in some respects.
Amazing animation, well done!

Now imagining having an exam about this in a few weeks and how I am feeling...

Amazing 3d modeling

Excelente Animación.Asi se entiende el funcionamiento del Rotor del Hely.
Which CAD system was used to build and animate this? Thanks for great visuals!

Wow, this is grate!!!!
Excellent, terrific insight to the dynamics of the mechanism!
very educates me
Beautiful work...
ZiggeyFreud Hello
Unfortunately all parts are moving and the input is not very clear. This makes understanding the Bell rotor hub not very simple as was expected.
Amen to that zaelu, this will perhaps confuse the ones that engineered it as well.
tryingto fully comprehend the joint movements and visualize it is like learning nuclear physics, that why they made gyrocopters..
Not really. Gyrocopters were made to avoid the pitfalls of a regular airplane that is prone to stalling. In theory a gyrocopter can never stall.

Good
Very good Rendering please tell me about software is used for rendering.

Seems overly complicated, this makes the animation that much more impressive.
The Hiller Main Rotor turns in a counter-clockwise totation... This vid is screwing with my mind...
it dose NOT show the effect of the fly bar that makes the video point less
the cyclic control is done with the fly bar the fly bar is kind of controlled by the swash plate
I like it

Super
Definitely more confused now, should of started with some different videos I guess.
i still don't know what the mechanism is trying to achieve?
Got it
what the fuck crossjoints!!!
that breaks my head!!!!
I'll stick to my fly bar less thank you. It petty and all but would not like to fix it in a case of a crash

beautiful presentation but difficult to understand i think.

Too much music...! :-(
Good music
so WTF is this? is it meant to be like the K-Max servo flaps just laid out different?
Where to buy helicopter rotor?

What is the function of flybar?
to provide stability to the rotor head.
@@nighthawk0077 then why it is not there in all rc helicopter and real helicopter.. just curious to know.
@@narendra848 it's not there anymore because stabilization is now done electronically via the flight controller/3 axis gyro
