Fascinating theory, proven in the wind tunnel.
Wind tunnel has no basis in reality. The common thought that air flow can be scalable, without the effects of the weight of the aircraft and associated lift, is simply outlandish.
Since you cannot have a full scale aircraft, and cannot have the full weight of the aircraft and associated lift, there is little that is accomplished other than proving calculations that are based on the calculations. In reality, since the foundation of the calculations are the calculations, if they did not prove themselves...well.
