When we compare rotor system designs....particularly the BO-105/117 series with the rigid rotor system which has been quite successful, against say a fully articulated rotor system.....would the rigid rotor come closer to reacting like a gyroscope than the articulated head?
The phase lag on a Lynx rotor head was quite a way from 90 degrees so No, I don't believe so.
Another factor is the relationship of blade inertia to aerodynamic damping (Locke Number if memory serves) where a heavier blade will flap further than a light one given the same aero forces or the same blade will flap more when aero forces are reduced (high DA for example).
