Small-scale coaxial-rotor assemblies are commonly utilized in Unmanned Aerial Vehicles to provide a compact design solution for achieving increased thrust potential and flight stability. The presence of two rotors operating in close proximity to each other results in aerodynamic interactions that have a profound effect on the individual rotor performance. A dedicated coaxial rotor test bench was developed for the purpose of testing various setups in a multi-rotor arm configuration. This study in... »
