To vorticey :
I agree with all you say. This thread was done as a mind game to provoke thought about the concept of a cyclical type of Coriolis.
Perhaps my earlier description was not clear enough. For the fun of it, envision the situation of helicopter flying at night. Every one of the blades has a light at its tip. There is a camera mounted 50 feet below the craft and pointed straight up at the rotor disk. Looking at the camera monitor during level flight will show a circular ring of light.
If this helicopter was then to be put in a sustained roll for a few seconds, the circular ring will now appear as an ellipse. To me, this could be an example of a temporary or cyclical Coriolis.
In a teetering rotor, the knuckle joint is handling the rotational acceleration/deceleration between the blades and the mast. In a flapping rotor, the lead-lag is handling it.
