Since it has now been proven by Volocopter and perhaps Ehang that it is feasible to carry a human with an electric multirotor, here is my stab at the topic. Please feel free to comment and criticize to your hearts content.
The PAV was modelled in Solidworks.
I want to experiment with the wings freely pivoting during hover and transitioning to forward flight. Since a multicopter is capable of considerable forward speed even with the rotors still facing up, the wings could be allowed to align themselves with the relative airflow. This way they won't interfere with the control effect of the motors, whose varying thrust controls motion around and along all three axes during hover. Once the wings reach their end-stops on the fuselage during fast forward flight, they then start to generate lift. The rotors tilt forward, and once they reach their fully horizontal position, the motor nacelles interlock with the wings. Pivoting the motors slightly will then move the wings as well, and control inputs should have the same effect as the controls on a canard airplane, plus the effect of vectored thrust on each wingtip. The manoeuvrability of such a machine should be quite incredible, given the need for enough thrust to exceed the weight of the whole aircraft.
In addition, there will be a motor to drive the rear wheel and everything folds up into the parking space of a car. I can’t wait to try it…
