Fanwing Technology

Thanks to Ken Holmberg for this info on "FanWing" technology.

Designs to establish a means of integral lift and thrust using a horizontal-axis wing rotor are recorded back as far as the late 19th century. Some of the experiments started to take off but did not sustain flight. The FanWing's new blown-wing solution offers both basic proof of concept and a steady trajectory of improved and controlled flight performance. Blown wing technology is not new, you can see a practical example of it in the Boeing C-17 Globmaster transport aircraft (bit it isn't exactly what this FanWing does).

The aircraft has a cross-flow fan along the span of each wing. The fan pulls the air in at the front and then expels it over the wing's trailing edge. In transferring the work of the engine to the rotor, which spans the whole wing, the FanWing accelerates a large volume of air and achieves unusually high lift-efficiency.
