It is a flying wing design. The middle of the wing is split in 2 with a hole in the middle which allows air to flow through will using VTOL.

Is this clear for you Lnewqban?
It is clear now, thanks.
The lack of wing for horizontal level flight is the main problem that I see.
The wing will be useless for lift where the propellers-motor are, close to the edges of those openings, and by the sharp wing tip.
The thrust line for hovering should cross the CG, which should be at 25% of the MAC for horizontal flight on the wing.
