With apologies to connavar, and probably many others.

[(aerodynamic) vertical thrust] = [(dynamic) impressed angular momentum]
Without the blades, there is no means of applying the above to the rotor.
This is the story;
The aerodynamicist will collect a large number of variable, such as; pitch, angle of attack, RRPM, forward velocity, air density, chord, airfoil profile centrifugal force etc., etc. etc. He will then calculate [
the height that the blade will fly to], at the azimuths of interest.
The dynamicist will simply come along and steal from the aerodynamicist [the blades vertical thrust at all azimuths], which is a byproduct of the aerodynamicist's hard work. He will then blend this thrust into the rotor's rotational momentum, which he also stole from the aerodynamicist, and then calculate [
the height that the blade will be forced to] at the azimuths of interest.
