This paper presents a methodology for modelling the thrust, drag, and torque of propellers used in unmanned-aerial-vehicle (UAV) applications. The model can be used in wide flight regimes from hover to high speed forward flight and is derived from first-principles using Blade Element Theory (BET), Blade Element Momentum Theory (BEMT), and a parameter fitting procedure to determine aerodynamic parameters. The methodology is applied to three different types of propellers to showcase its versatility, and experiments show that the procedure can accurately predict the rotor forces. Wind tunnel measurements are also included to serve as an additional basis for comparison. A comparison to static thrust models typically used by roboticists is also shown.
