| Abstract |
This study presents the design and fabrication of a scaled Urban Air Mobility (UAM) vehicle based on a central tilt-hexacopter configuration and experimentally investigates attitude asymmetry and stability variations during transition flight. By tilting only the two central rotors while keeping the remaining four rotors fixed to sustain vertical lift, the proposed configuration exhibited relatively stable transition responses, with roll?pitch deviations generally maintained within ±10°, compared with typical tendencies reported for tilt-quad systems. Minor yaw?pitch coupling observed in flight tests was attributed to slight tilt-rate imbalance and sensor alignment offsets, interpreted as thrust-vector deviation caused by mechanical tolerances. These findings suggest the need for thrust-alignment control and in-flight calibration algorithms to further enhance transition-flight stability in tilt-type UAM platforms. |
