Bell Hiller Helicopter linkage demonstration slow motion

This video was shot with the helicopter held down and about 1/3 normal flight RPM with very little collective pitch. It was shot at 600 frames per second and shows how the cyclic control moves the swash plate (at bottom center) which in turn is linked to the flybar and main rotors. It probably is not 100% accurate compared to what happens in actual flight but is interesting to see the mechanics of the rotor head.

Belt CP?

@hutadut Hmm... belt? I'm not sure what you mean, but this heli has no belts. It's got gear driven main rotor and a shaft driven tail rotor. Some helis have belts for the tail rotor I think.

Thanks! I think it's very revealing to see it in slow motion.

Из истории советского и российского вертолётостроения известно, что автомат перекоса изобрёл[4] русский учёный Б. Н. Юрьев в 1911 г.

@krouviere Oh the rotor head looked like the one on an Esky Belt CP.

at least one guy dit NOT understand it ;)

i wonder how it brings something up and down.. amazing

...When you think of how fast that head spins when in flight - its amazing these things dont self-destruct more often!! Thanks for the Video!
