Cool animation. I worked on the CH-53K test flight instrumentation crew, we put a go-pro on one of the rotor blades, and, I wish I had the footage but, it showed really well how much the blades are moving in flight. Was really cool.
That's cool. I worked in V-22 osprey flight test for awhile. I did this animation with a tip mounted camera on an intermesher helo... czcams.com/users/shortsHFGpQslvS70?feature=share
Not sure if this is the same footage but it's the same idea. czcams.com/video/Pu48f7s5Ru8/video.html&lc=Ugz0gz7iH3ZXwvjbgWd4AaABAg.9n9m9XuEXXE9w9j9N9sIUN
I find it amazing how some of the components are able to withstand the forces that act upon them which I imagine is pretty substantial. Like the three rods that go from the swash plate to the rotors.
Quite a good animation of the operation of a swashplate, but it is missing two important elements. The upper and lower parts of the swashplate ( known as upper and lower star), both show a connection for the stabilising scissor connection, but the scissors are not shown. The lower scissor is attached to the gearbox housing and allows for the vertical and tilting motion whilst preventing rotation of the lower star, and the upper scissor is connected to the rotor head, so that it drives the upper star. In the animation the only things connecting the upper star to the rotor head are the pitch change links, and these are intended to provide vertical motion only, not to transmit rotational force to the swashplate. Otherwise this is a good representation.
Nice observation and explanation! I had the scissors in the original cad, but figuring out the motion constraints for the animation was beyond my abillity at the time. I made a subsequent animation that shows the scissors.
You are going to have a real problem with the blade axial bearing that must support the very large centrifugal load of the blades with reasonable friction to be cyclically moved. HC-47 has torsionally soft steel bands to carry the load.
Good observation! The design has openings for TT straps between the flap hinge and the lead-lag hinge But I didn't model them. I made this to demonstrate and educate; not necessarily as a legitimate design proposal.
The Kaman K-Max actually uses fixed blade grips and control flaps on the trailing edge of each blade operated by 1/4" push pull rods inside the blade. Rather than changing the angle of attack at the shoulder the pitch control links operate the push pull rods to move the control flaps and the whole blade twists along it's lenght. The K-Max is a weird helicopter though.
@@atomicskull6405we need a stiff outer part to carry the bending and a thin inner part to carry centrifugal. But how would you balance this? Watt linkage? Hydraulic tensioner for the spring or for the bearing or both?
I’ve been flying these for 55 years. I’ve never seen better animation. I’m also a fellow in of the royal aeronautical nautical society. This is beyond anything they have ever done. Thank you for explaining it so simply, your animation skills are stellar..❤
There's a piece someone wrote called "helicopter pilots are different". A quote from that article... "They know if something bad has not happened, it's about to"
Indeed - as an object which chooses to obtain lift & stability the way a helicopter does - you should only ever be in one _if you absolutely have to fcking be!!_

Yes, the action of the rotor blades where they change their angle relative to airflow is called "feathering". The swashplaye allows them to feather equally which is called "collective" feathering, or individually which is called "cyclic" feathering.
You are correct... I only modeled blade pitch. IRL, the blades would flap in response to the blade pitch and this rotor tilt the disk left, right, forward or aft. Check out my other videos... I did one that shows the behavior you're asking about.
I modeled this after hydraulic cylinders that I've seen. Most large helicopters use hydraulic cylinders, although I've heard electro-mechanical actuators are getting more capable.
Yes, most helicopters of this size have 4 blade systems. I did an earlier vid of a tandem helicopter, that uses 2, 3-bladed rotors. I reused the 3d model of that rotor.
Helicopters have droop stops to contain flapping at low RPM. I didn't model those. As far as over-flapping, this motion is aerodynamically well-damped. As the blade flaps up, the induce velocity increases, this deceased the blade aoa, and decreases lift.
Rotor blade droop stops under pressure from springs prevent the blades of fully-articulated helicopter rotor systems from "drooping" to the ground at no or low rpm then retract into the rotor blade roots with centrifugal force at high rpm. The centrifugal force of the rotor blades at high rpm is stronger than the blade "coning" force caused by rotor blade lift which prevents the rotor blades from flapping up uselessly. Yes, helicopter rotor systems operate under a lot of stress.

I never did like the fact that there are so many delicate parts of a chopper that if any one of them where to fail would cause a disaster
