The function is based on the mathematical treatment of rotating rotors in "Principles of Helicopter Aerodynamics" by Dr. J.Gordon Leishman

The numerical method does this by using Blade Element Momentum Theory (BEMT) to calculate the inflow along the length of the blade, then using that inflow and Lifting Line theory to calculate the local lift and drag on the blade.

The thrust and power are then calculated from the local values and summed along the length of the blades to give the totals.

This numerical method works for multiple blade configurations through the input parameter BChar, which is detailed in the header of the m-file.

This function has been used to form the basis of an optimisation problem used in the preliminary design of a rotary wing UAV.
