Question

To: Grey Area

I totally agree with you. Collective causes coning and cyclic causes flapping. All I was doing is to explain what is happening when the pilot pulls collective. In order to cone the blades must flap upward. That is what happens. This forms the collective cone angle. When the pilot pushes cyclic the blades will flap and the disc will tilt. On the advancing side the blades are flapping downward and on the retreating side the blades are flapping upward. Do we agree on that?

In establishing this tilt to the rotor disc there is a difference between the driving axis and the driven axis. It is this difference that causes the leading and lagging. Do we agree on that?

If we don’t agree on these two points then it is you that have the problem not me.

This last statement is not meant to be offensive.
