Abstract

In this study, the performance characteristics of a rotor used for multirotor are investigated through wind-tunnel tests. The rotor is tested at several flow speeds and angles to approximate the actual flying condition. A high resolution six-axis force/moment sensor is utilized to record the forces and moments in three directions. Wind tunnel results show the changes in the rotor performance with the variation in flying speed, flying angle, and rotor revolution. The results also demonstrate that the aerodynamic characteristics of the rotor quite differ from those in the hovering state when the vehicle is flying forward. Finally, aerodynamic models of the rotor in forward state are provided.
