Humle - Hvorfor skal den ikke kunne fly?

[Gromle]

Har lest noen plasser at i følge vitenskapen skal egentlig ikke en humle kunne fly. Hvorfor det egentlig? Noen som kan berike min hjerne med litt info rundt det?

Det dreier seg nok om noen misforståelser, men i hovedtrekk går det på det at humlen veier for mye i forhold til det løftet de små vingene skal kunne gi.

 

Første google-søk etter "bumble bee cannot fly" gav denne linken.

A long-held myth of the bumblebee was that, in terms of theoretical aerodynamics, it did not have the capacity (in terms of wing size or beat per second) to achieve flight with the degree of wing loading necessary. This myth became popular after an aerodynamicist in the 1930s stated that a bumblebee was not capable of flight. The statement was based upon an assumption that the bee's wing could be treated as a static aerofoil. However, in reality the bumblebee's flight is characterized by an oscillating wing that shares more characteristics with a helicopter rotor than an aeroplane wing.
