All bets are off.
You guys mentioned, correctly, that in sketch [B] and [C] the line between the blade centroids will be above the virtual hinge when the helicopter is operating at mean thrust.
Thanks again for finding fault and instigating a revision.
Please (do not
) find fault with sketch [D]
This configuration is identical to [B] and [C], except that there is now a Tie bar, which holds the two yokes at the pre-cone angle.
Should one blade flap (teeter) up then the other blade will flap (teeter) down. This is now operationally identical to the conventional teetering rotor [A]. In other words, under mean thrust, the line between the blade centroids will pass through the teetering center on [A] and through the virtual center on [D]. Even when disks [A] and [D] are tipped, this line will still pass through the center of both configurations, under mean thrust.
As with [B] and [C] the offsets in [D] will result in a more powerful cyclic control then that of [A].
