The bumblebee flightThe bumblebee flightDer Hummel-Flug
The legend says that a bumblebee is too heavy for its small wing surface according to the laws of physics and therefore should not be able to take off (bumblebee paradox). The mistake in this is that insect wings are not rigid lifting surfaces like on an airplane. Bumblebees beat their wings up to 200 times per second in a circular motion. This creates small, tornado-like air vortices at the leading edges of the wings. This effect generates a strong dynamic lift that easily keeps them in the air.The legend says that a bumblebee is too heavy for its small wing surface according to the laws of physics and therefore should not be able to take off (bumblebee paradox).

Der Irrtum dabei ist, dass Insektenflügel keine starren Tragflächen wie bei einem Flugzeug sind. Hummeln schlagen ihre Flügel bis zu 200-mal pro Sekunde in einer kreisenden Bewegung. Dadurch erzeugen sie an den Flügelvorderkanten kleine, tornadoartige Luftwirbel. Dieser Effekt erzeugt einen starken dynamischen Auftrieb, der sie problemlos in der Luft hält.
