How does it work? The aircraft has a cross-flow fan along the leading edge of each wing. The fan pulls the air in at the front and accelerates it over the trailing edge of the wing. By transferring the work of the engine to the rotor, which spans the whole wing, the FanWing accelerates a large volume of air and achieves a high lift-efficiency.
). Anyway, it also produces a herendous amount of drag so it's definately not a high speed application. It's a very simple mechanism with just a piston engine on the current prototypes running the fan and the fan acts as the propulsion device as well as helping to produce lift.
There are plenty of conventional planes that would drop out of the sky with engine failure and many have one engine. If they want this thing to get airborne (so to speakTomba wrote:important for airplanes is the reliability, and I wonder what happens if the engine fails. When some sprayer plane gets engine troubles if can be put to the ground quickly, it may be a rough landing but you'll make it if you're not flying too high.
However, with this high draw wing, engine trouble may immediately drop your plane's speed... and what then? Does that wing generate enough lift to not let if fall down like a rock from the sky?
) then they will find a way to manage the risk.
) there's a little airfield for RC planes and RC dirt buggies. There was a guy who had one of those things, custom made I think. He came testing it a lot but even after three months it still didn't work. Immediatly after take-off it turned and crashed into the ground. I think it's just to unstable to fly and to make turns because if u want it to turn the fan of one wing has to rotate faster than the fan of the other wing. To do that he needed some complex differential sort of thing and he couldn't afford it. Those on the movies seem to work a little different though but they still seem very unstable.
