Aerodynamic interactions between rotors are important factors affecting the performance of in-plane multirotor Unmanned Air Vehicles (UAVs) or drones, which are the majority of small size UAVs (or mini-drones).Optimal design requires knowledge of the flow features.The low Reynolds number of many UAV rotors raises the question of how these features
