F = k_F\omega^2
M = k_M\omega^2
Measuring k_F and k_M
The values for k_F and k_M are generally found empirically. We mount the motor and propeller on a load cell and measure the force and moment for different motor speeds.
The graph below shows a simulation of the data you might get from such an experiment.
