Research of Transition Corridor and Optimal Trajectory for Front-Tilt-Quadplane eVTOL Aircraft

Urban air mobility is undergoing a booming development. Electrical vertical takeoff and landing (eVTOL) aircraft has drawn great attention from industrial and academic communities recently. In this paper, a Front-Tilt-Quadplane configuration is proposed and dynamics model of full-mode flight is proposed. Control-stability characteristics are analyzed within different modes. Then transition corridor is calculated with limits of attack angle, thrust and stalling speed. Finally, the transition control strategy is analyzed with trajectory optimization technology.
