Are there equations to match power required to mass for rotorcraft?
The simplest way is using the momentum theory, by which the thrust $T$ generated by a rotor is:
$ T = k\sqrt[3]{2 \rho A P^2} $
where $A$ is the rotor area, $\rho$ is the density and $P$ the power ...

Are there equations to match power required to mass for rotorcraft?
In a hover, the figure of merit $FM$ is defined as the ratio of the ideal power required to the actual power required.
$FM=\frac{P_\mathrm{ideal}}{P}$
Typical values for the figure of merit are about ...
