bumble bee's


How do bumble bee's fly?? Answers please!! I have spent 20 years of life wondering how they do it and i still cant explain it!! maybe i need to commit another 20 years to the cause.

Ive heard, although I can't be certain, that it's an impossibility for a bumble bee to fly, it's scientificaly impossible. Pretty cool creation huh.

Why wouldn't they be able to fly, maybe with their wings, im confused....

Jamie said...

No apparently their body weight is too big for the size of their wings to make them fly. Yes they do fly but scientificaly speaking they shouldn't be able to, and yet they can. Interesting

bugs in general were thought of as a mystery in terms of flight.

it was recently figured out through aeronautical science research that a bugs wing creates a vortex under the wing when they flap their wings. This creates lower surface pressure under the wings, and allows for more efficient uplift.

Check out 'Extreme Machines'
"flight of the future'.

i saw it on one of the science type channels.

According to 20th century folklore, the laws of aerodynamics prove that the bumblebee should be incapable of flight, as it does not have the capacity (in terms of wing size or beats per second) to achieve flight with the degree of wing loading necessary. Not being aware of scientists "proving" it cannot fly, the bumblebee succeeds under "the power of its own ignorance".[26] The origin of this myth has been difficult to pin down with any certainty. John McMasters recounted an anecdote about an unnamed Swiss aerodynamicist at a dinner party who performed some rough calculations and concluded, presumably in jest, that according to the equations, bumblebees cannot fly.[27] In later years McMasters has backed away from this origin, suggesting that there could be multiple sources, and that the earliest he has found was a reference in the 1934 French book Le vol des insectes; they had applied the equations of air resistance to insects and found that their flight was impossible, but that "One shouldn't be surprised that the results of the calculations don't square with reality".[28]

Some credit physicist Ludwig Prandtl (1875–1953) of the University of Göttingen in Germany with popularizing the myth. Others say it was Swiss gas dynamicist Jacob Ackeret (1898–1981) who did the calculations.

In 1934, French entomologist Antoine Magnan included the following passage in the introduction to his book Le Vol des Insectes:

Tout d'abord poussé par ce qui fait en aviation, j'ai appliqué aux insectes les lois de la résistance de l'air, et je suis arrivé avec M. SAINTE-LAGUE a cette conclusion que leur vol est impossible.

This means:

First prompted by the fact of aviation, I have applied the laws of the resistance of air to insects, and I arrived, with Mister Sainte-Lague, at the conclusion that their flight is impossible.

Magnan refers to his assistant André Sainte-Laguë who was, apparently, an engineer.

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.[29]

Another description of a bee's wing function is that the wings work similarly to helicopter blades, "reverse-pitch semirotary helicopter blades".

Bees beat their wings approximately 200 times a second, which is 10–20 times as fast as nerve impulses can fire. They achieve this because their thorax muscles do not expand and contract on each nerve firing, but rather vibrate like a plucked rubber band

@ Jamie: Nothing is impossible for the Creator.

"Verily! In the creation of the heavens and the earth, and in the alternation of night and day, and the ships which sail through the sea with that which is of use to mankind, and the water (rain) which Allah sends down from the sky and makes the earth alive therewith after its death, and the moving (living) creatures of all kinds that He has scattered therein, and in the veering of winds and clouds which are held between the sky and the earth, are indeed Ayat (proofs, evidence, signs, etc.) for people of understanding."

[Qur'an 2:164]
