According to the laws of aerodynamics, May bats should not fly.
Theoretically, the May bush is a Boeing with a motor from a motorbike.
When the wing of the beetle moves downwards, a lifting force is created and in addition to it, due to some turn of the wing, a pulling force is also created. At the same time, there is also a sinking of air into the space between the wing and the wing. At the bottom dead point, the wing of the beetle unfolds and changes the angle of attack. Now, when moving upwards, the wing pushes out the air from the space under the overwing. Moreover, the resulting air stream creates both the lifting force and the pulling force at the same time, since this stream is directed at an angle down and back. Thus, it turns out that the May beetle has a combined flying and reactive flight.
If the May Beetle had read THIS, he would have killed Apsten without thinking.
