but thats the whole argument right?
whether this manoeuvre actually creates any added stress on the parts like the elastomers is a hard fought debate. Some think total aircraft destruction is imminent. Some think who cares. Others sit on the fence. I can tell you after seeing an EC120 Main and Epi Module with Rotor Head, all decked out in Airbus' stress monitors, I can assure you, they have every single component wired up to gather the data they need to know they have built a component capable of the flight envelope they tested the design at. with a healthy safety margin I imagine.
The frequency adapters and the spherical bearings react on the rotor head the same way no matter the attitude. The gearbox doesn't care if it's flat and level or 45 degrees. The tailrotor and drive is oblivious as to whether its doing a hard pedal turn, or lifting a max gross external load.
