Paul:

I believe a Rotary would be a good application for this as a full
size plane. You could drive off the front and rear of the engine at the
same time which would keep the package really light. I can't figure out
the theory of how it really works. Do you have any idea?

Nothing really new here. It uses the coanda effect
and  pumps air over the lifting surfaces.

When scaled up the devil is in the structural details.

Anyone interested should contact The Yankee Airforce.
Before it was destroyed in a hanger fire, one of their
Restoration projects was an experimental NASA plane. It was
a high winged twin turboprop that had hugh Fowler Flaps
with rotating horizontal cylinders fitted with air nossals
in the gap between the wing and first stage flap. These
cylinders used bleed air to rotate and expel air over the
flaps to maintain laminar flow, the claim was that its
stall speed was around 30kts.
