So....now that I have had a chance to absorb all this, it appears I don't know what I thought I knew. Now that I think I know what I should have known...I will adjust my question accordingly.
If the phase angle displacement is due to aerodynamic forces and the time it takes each blade to react to the inputs as they are provided, then how does one account for this from a design perspective? Is it a matter of calculating the increase in lift due to a control input and how long that force would take to move the blade to its new position? I'm sure there is a way but just seems like there would be a ton of factors at work and hard to engineer correctly right out of the gate.
Thanks for all the input so far. BTW I did read Prouty's book long ago but can't find my copy to reference for this question.
Thanks
