Nested Power Models for Multirotor Propulsion: From Aerodynamic Drag to Electrical Losses

Key points

• Speed-only aerodynamic power models for multirotor propulsion cannot represent acceleration-dependent effects.1
• Independent estimates of rotational inertia and aerodynamic drag complement predictive validation by assessing whether the models correctly attribute the measured power to reversible kinetic-energy exchange and irreversible dissipation and, within the latter, to aerodynamic and electromechanical losses.1
• The results show that the reversible kinetic-energy rate is necessary but insufficient for accurate dynamic power prediction.1
• The resulting methodology provides a reusable and experimentally verifiable basis for developing and selecting dynamic propulsion-power models for multirotor systems.1

  This work develops a nested sequence of propulsion-power models that starts from aerodynamic power dissipation and progressively introduces a reversible kinetic-energy rate, torque-dependent electromechanical dissipation, and lumped speed-proportional dissipation.
