I am interested to hear what others think of Dr. Ullman and his research on using ducted fans to increase lift with the Coanda affect. His goal is to allow near VTOL with diminished induced drag and less wing area.

Integrated Distributed Electric-Augmented Lift
Distributed Electric Propulsion using electric ducted fans
Dr. David Ullman Vincent Homer
NASA, with the X-57 is similar but not using ducted fans and according to Ullman giving up the reduction in induced drag.
Thanks
