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.
Great artwork, on swashplate assembly there is bearing called spherical bearing, will move together with swashplate assembly. To move all the axis x, y and z, this kind of main rotor assembly must have an input from right lateral servo, left lateral servo and fore & aft servo by moving collective and cyclic stick weather up, down or forward. Need to included bifilar absorber...?
Does the internal part of the swash plate where it contacts the tilt-bearing actually rotate with the rotor? If so, why is there a bearing between the inner part of the swash plate and the outer part where the pitch links are attached? Excellent work, thank you!
The dark blue part is called the rotating swash plate. It sits on a ball so it can rotate in all directions (cyclic) and the "ball" can move up and down (collective) around the main axle.
@fozzy40sqn ok, one more question, the red thing wich is mounted on the swashplate, (the one that rotates with the rotor) what is it for??? looks useless and possible a vibration cause, (other than giving the rotoro certain integrity) Thanks a lot! ... I would appreciate more precise links to related data, if you have.... :D
You see the red parts two times, they are called the scissors. The aim of the lower one is to keep the stationary swashplate stationary to the helicopterframe and for the upper one is to keep the rotating swashplate stationary to the rotorspeed. With stationary I mean only in the rotation axis off course.
Excellent animation. With some comentary this should go on 'How stuff Works' as it shows far better how the main rotor hub works than what someone could explain in writing.
Yours is a great animation. At the beginning, I was misled by the fact that the green box rotates. I would have thought that part should remain stationary. Anyway, thanks.
@shiifaa You're right, the green box is stationary in the helicopter. It rotates because I Coupled the camera to the rotating parts. Thanks for your comment.
do you think this is possible with solid edge? what did you do to get the draft for the parts? just curious, I'm in the middle of my designing class project and I'm having problems with the little parts of the rotor
The sleeve-and-spindle assy of the nbr. 1 rotorblade is not equiped with parts of the blade-fold system,except from a pressure accumulator. A counterweight is installed in this sleeve-and-spindle assy, to balance the absence of the blade-fold parts that are on the other 4 sleeve-and-spindle assy's. The weight of this balance weight takes into account the weight of the rotating scissors, that are directly below it, to balance the totallity of the rotorhead-swashplate-scissors.
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
A brilliant animation, but I'm a bit thick, so am I right in thinking that the rotor blades are being spun by the central shaft and the top red scissor is then spinning the blue part of the swash plate? If there is only one top scissor, why does this not imbalance the rotor head? Is the swash plate everything in the animation except the bottom green gearbox, the central shaft and the rotor blades and what exactly is the difference between cyclic and collective?
You're right about the spinning stuff. I'm not sure about the imbalance, but I think they hung some kind of counterweight on the other side of the rotating part of the swashplate (blue). The swash plate constists of 2 major parts, the stationary (grey part below the blue one) and the rotating part (blue).
Collective means, the swashplate moves only up or down without rolling and or pitching. This results in changeing the pitch off all rotorblades simultaniously. (collective) This is used to move the helicopter up or down. The collective is controlled with the pilot's left hand.
Cyclic means that the swashplate is moving in roll and or pitch. This results in moving the pitch of the rotorblades in a cyclic way. On one side of the helicopter the pitch of the blade will be high and on the other side the pitch will be low. This is used to control the helicopter in roll and pitch. The cyclic is controlled with the pilot's right hand. As on a fixed wing, the pedals are used to control the yaw (changes pitch of the tailrotorblades).

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.
@1SpiritOfTheWarrior1 The red scissor is there because the rods between the s-plate and rotorhead would brake from the side forces without it. Choppers with as many as 5 blades usually have one single damper per blade and yes it needs a vertical joint for that purpose. I dont think the blades rotate 2 times per rev. it looks like that because the swashplate changed angle from one side to the oher.
6 sekunder sedan And what about the red scissor.. The connection to the swashplate is impossible. It is stuck and can still move..check "Helicopter" on Youtube. That video is correct. The purpose of the red scissors is to transfer power from the pole and head to the swashplate so that no breaking force in any direction is taking place through the thin pins connected to the flaps. The plate shall rotate in the same speed and still be able to move in all directions
If you look at a close up picture of real swashplates you´ll see thar the scissors are even attached to the pole dicetly above the plate. Maybe sea king rotorheads are different...?
The rotor pole is moving but the head is still? Makes no sence at all. You can see it on camera 4. The pole runs the head in all helicopters. Something wrong here. The swash plate sticks cant possible stand for the power transfer, it would cause side forces in all direction.
@MrThundermouth U seem to know about this.... so tell me (I'll keep it simple because don't know names of these parts on english).... The red thing that connects the blue ring thing with rotor head, what does it do? 2. Isn't there suppose to be a joint for every blade that allows the rotor to move horizontal in relation to the hub....? 3. If the rotor looks like this immage shows, that means that the angle (pitch) of each blade changes 2 times per revolution in relation to the rotor head???
WOW!....like everybody else said. I just learned EVERYTHING there is to know about helicopters in seven minutes and twenty-one seconds. Wait a minute.....what are the bright green thingys behind the blades at the shaft? Are they snubbers of some sort? Dampeners? Would they be for absorbing the shock of going suddenly from into the wind to away from the wind?
WOW! That's absolutely incredible! Great job transforming something so complex, into something easy to watch and follow. Colors to highlight the different components, the various camera views, and slow motion are all really nice touches. Thanks for putting all the thought and effort into it, and then posting it for the public.
Very nice. What is the purpose of the two red-hinged brackets, especially the upper one attached to the moving / blue swashplate? Are these supposed to keep the swashplates from deviating their angle too much from the rotor disc?
That's correct. They are called "scissors" and the purpose is to keep the lower part of the swashplate stationary to the gearbox and the upper part of the swashplate stationary to the rotor.
I was going to ask exactly the same thing but Lavalamp beat me to it. I guess its best to have the link take those rotatary forces, not the control rods and rams. Though I wonder how they balance the mass. How does the flapping mechanism on this helicopter work and stay in balance during forward flight? Thats the thing thats got me baffled in all helicopters at the moment.
