For the experiment, scientists placed the bats in a wind tunnel filled with light smoke and laser-illuminated, which made it possible to better see the movement of air currents during the flight. The flight speed was up to 5 m / s.
It was found that the wings of animals act similarly to the wings of aircraft – create a lift, even with a slow flight. To do this, bats have to spread their wings widely at the end of each bar.
According to Johansson, this particular way of generating energy will help in creating new mechanisms for aerodynamic control of unmanned aerial vehicles.
