Aurielius Posted May 16, 2012 Share Posted May 16, 2012 Good grief! Well, yes I guess that did make me feel a bit better; at least the one tenth of it that I could comprehend. But that of course still leaves us with the bumble bee. No one understands how he can fly :rolleyes: :tongue: Seriously though. Thank you for that. I do appreciate it. :thumbsup: "The lift coefficient contains the complex dependencies of object shape on lift. For three dimensional wings, the downwash generated near the wing tips reduces the overall lift coefficient of the wing. The lift coefficient also contains the effects of air viscosity and compressibility. For very low speeds (< 200 mph) the compressibility effects are negligible. At higher speeds, it becomes important to match Mach numbers between the two cases. Mach number is the ratio of the velocity to the speed of sound. So it is completely incorrect to measure a lift coefficient at some low speed (say 200 mph) and apply that lift coefficient at twice the speed of sound (approximately 1,400 mph, Mach = 2.0). The compressibility of the air will alter the important physics between these two cases."- NASA Does that help at all granny? It was the simplest explanation I could find. :whistling: Link to comment Share on other sites More sharing options...
csgators Posted May 16, 2012 Share Posted May 16, 2012 I thought you just needed happy thoughts and fairy dust. Link to comment Share on other sites More sharing options...
grannywils Posted May 16, 2012 Share Posted May 16, 2012 Oh, absolutely Aurielius. Thank you ever so much. Now I have it fully inscribed in my brain............:no: :unsure: :mellow: :turned: :blush: :wacko: :( Edit, oh and about that bumble bee?????

Aurielius Posted May 16, 2012 Share Posted May 16, 2012 (edited) Oh, absolutely Aurielius. Thank you ever so much. No I have it fully inscribed in my brian............:no: :unsure: :mellow: :turned: :blush: :wacko: :( Edit, oh and about that bumble bee?????Well we could go with CS's theory and use Fairy Dust while repeating: I do believe in fairies..I do.Edit: In theory bumble bees shouldn't be able to get lift....pollen must substitute for fairy dust...lol Edited May 16, 2012 by Aurielius Link to comment Share on other sites More sharing options...

You got your response in before I had an opportunity to edit out all my errors. Well, anyway thanks for the "help", Pal o mine!:thumbsup: Link to comment Share on other sites More sharing options...
HeyYou Posted May 17, 2012 Share Posted May 17, 2012 Bumble bees can fly, because they don't know about the laws of physics, and no one has successfully been able to tell them........ Link to comment Share on other sites More sharing options...
