Abstract

The manoeuvrability of the Urban Air Mobility (UAM) determines its handling qualities and safety. However, this novel rotor-powered vehicle configuration has unique characteristics, including the complicated aerodynamic interference of the multi-rotor systems, the transition mode that may alter the...
