Does the application of forward cyclic on a hovering helicopter with a 'basic' teetering rotor cause an immediate tilt of the disk to the right?
Dave, picture this for a moment; a spinning solid disk in an ideal setting used to demonstrate precession will have a force at
one particular point, applied to make the disk/wheel etc tilt. … now back to your rotor……
Still moving the cyclic forward in a steady state hover ……the difference here to the solid disk demo., is that in your helicopter rotor, the force/couple from the blades changing pitch acts in a relatively gradual manner!
The blade pitch angle, which determines the amount of cyclic force, takes 180 degrees before it gets to its maximum or minimum value. During that gradual change the force/couple has already started to tilt the rotor disk to an angle that precedes the desired disk tilt.
In this instance, the overall tilt down is to the front but a with a slight right hand component, which was instigated by the lighter but increasing force/couple prior to the blade reaching its max or min pitch angle.
Is that what you mean by “washed out coupling”?
The tilt down at the front becomes a tilt to the right by a few degrees. Therefore, my answer to your last question is “yes”.
