You might like this post also from today describes a simple science fair like way to demonstrate the effects of hinged flap surfaces. I called it a Venetian valve wing but whatever.. https://news.ycombinator.com/item?id=28950161 https://news.ycombinator.com/item?id=28950161 I thought about it a year ago but put it away due to no interest from my peers. I only brought it up to news.ycombinator recently because of the cut scenes from the new dune movie. You can try the experiment for yourself. It does in fact work. The only immediate benefit I see so far is that trust power does not get sheered at the edges with super sonic helicopter edges. Meaning the flaps, even if they are traveling at a whopping 100 meters per second are moving far less than would cause a super sonic shock wave like helicopter blades. An aircraft built around it would be more maneuverable, and have more lift power than similar sized aircraft. I can almost picture an ornithopter picking up a tank and transporting it to the battle field with the lift these things can develop. I'd animate it but there seems little point. This thing is going to show up soon and neither of us will get credit for the idea. But it does work..
