A cyclocopter is a weird sort of aircraft that uses airfoils rotating around a horizontal axis to generate lift and thrust. The concept was developed about a century ago, but these things are tricky to build and fly, so they haven’t, er, taken off as much as helicopters have. In fact, there’s only a small handful of research groups working on cyclocopters at all, and at the moment, they’re focusing on small scales. Moble Benedict at Texas A&M’s Advanced Vertical Flight Laboratory has been testing the smallest cyclocopter ever developed: It’s just 29 grams in mass, and could be a tiny step towards replacing helicopters and multirotors with something better.
