Does the Lilium VTOL wings produces lift during takeoff? I just had a look on some of the recent development in the personal VTOL electrical aircrafts. 
I am wondering if the Lilium VTOL wings produces lift during takeoff?
I would expect a quit high wind speed moving over the wing generating negative pressure, hence, beside the thrust force generated by the fans additional lift is generated over the wings? Is this correct?
The take off is aided purely from the mini fans which is pointed vertically at the aft of the wing to generate pure vertical thrust. The wings will generate only drag and zero lift because the airflow(aerodynamic force) is attacking perpendicular to the chord line. Hence the wings are used only to aid the flight in cruise.
