[Closed] Flying/aerodynamics question. How does this work?

We all know how fixed wing aircraft work;

Even with my limited knowledge of physics I know how helicopters, hot-airballoons, airships and ornithopters work (or don't work in the case of ornithopters)
However, in this picture of a magic carpet the front is half rolled up in the usual way [IMG] [/IMG] but I beleive this design for the leading edge would create a vortex as the air passing to the underside would follow the surface of the carpet around and end up trapped in the fold, the bottom set of arrows in my picture, making it extreemly unstable, or at least creating an enormous amount of drag.
Am I missing something or the design intended to be unstable in the same way that, for example, a Eurofighter is?
Also, on the one in the photograph there appear to be very few, if any, controls for the pilot. How does the autopilot system work on these? There's nothing on the Boeing, GE or BAE websites about this. We have a carpet fitter at work at present in the top floor office, I asked him, assuming that someone who worked in the industry would know but he was clueless on the matter.
