Cover Story: Coaxial multirotors, thanks to their overlap, offer a compact solution for increasing payload capacity, whilst still facing performance challenges due to airflow disturbances. This article investigates coaxial multirotors’ aerodynamic disturbances, presenting two new models which account for rotor overlap effects on thrust and torque. Each model is accompanied by its corresponding mixer, tested in both a simulation and a coaxial prototype. The findings showcase the potential of these approaches to increase the efficiency and performance of coaxial multirotor systems, paving the way for more reliable and powerful aerial platforms.
