As is McD NOTAR...
There are elements of Coanda, Blown Flap, and Bernoulli abounding....
As to Bernoulli, after staring at the ugly leading edge of the P-80, I tested an exaggerated camber wing. The upshot is, without AoA Bernoulli sucks eggs, and Newton rules. The difficult proposition is to mathematically calculate "o" AoA.
One cannot introduce enough airstream onto the leading edge to counter the equal split of drag at O AoA. The lifting force at 0 AoA is parallel the chordwise neutral line, and in opposition to the airstream.
