Interesting new aerodynamic concept here, a very thick wing with slots in it to improve lift to drag ratio.

I have no clue if it will work, though there is rather a lot of analysis that indicates that it might, but given the non-aerodynamic advantages of a thicker wing in terms of structure and volume, it is an intriguing concept.

It appears that this could be tied with some sort of bleed air technologies to work as control systems too.
