    Is the assertion that according to aviation experts bees should not be able to fly true?

    Question #118994. Asked by george48. (Nov 27 10 8:06 PM)

    		The urban legend is that bumblebees should not be able to fly, however...

    It is believed that the calculations which purported to show that bumblebees cannot fly are based upon a simplified linear treatment of oscillating aerofoils. The method assumes small amplitude oscillations without flow separation. This ignores the effect of dynamic stall, an airflow separation inducing a large vortex above the wing, which briefly produces several times the lift of the aerofoil in regular flight. More sophisticated aerodynamic analysis shows that the bumblebee can fly because its wings encounter dynamic stall in every oscillation cycle.

    		This sounds like Aristotle: belief is everything, ignore the fact that bumblebees actually can fly!

    Many years ago I was told that aviation fuel was always measured by weight not volume (pounds rather than gallons). Is that still true?
