The document at hand proposes a personal aerial vehicle (PAV) for daily commute and on-demand personal transportation. It features a quadcopter design with tilt rotors and “free” wings to extend the cruise range and speed.
The wings align themselves freely with the relative airflow they encounter during hovering and transition to cruise flight, with the goal to minimise negative effects of the wings on manoeuvrability during this flight phase.
The wing will assume a fixed angle of incidence during cruise flight and thus generate lift then. The project started in 2016 and a radio controlled scale model has been built and flown.
