[edit] Bees in flight

Since people editing here probably know a little a about aerodynamics, it would be nice to have a section on the Bee article to discuss the flight of bees.

In part I'm asking because on Sunday Image:Bee mid air.jpg is due to be the Picture of the day|Picture of the Day. However, at the moment I'm not too happy with the caption as it is a bit too general - it would seem better to mention the common misconceptions about bees not being able to fly. -- Solipsist 09:13, 28 October 2005 (UTC)

I believe the statement is attributable to some of the earliest investigations into aerodynamics, notably the derivation of the lift equation, which is an empirical formula based on observation of aerofoil sections in wind tunnels. According to the lift equation, Bees supposedly can't fly because the wing area, lift coefficient and weight of the bee don't fit the equation. All this says is that the equation is inadequate for bee flight, since bees obviously can fly. However, for some reason this statement entered the popular imagination, which probably says a lot about the presentation and understanding of science by the wider population. As far as I recall, the mystery was only really solved quite recently, perhaps as recently as the 1990s - whereby new research indicates that insect flight takes advantage of a variety of dynamic effects such as the formation of vortices by the rapid wing vibration which cancel much of the induced drag. In addition, insect flight needs to be analysed at much lower Reynolds numbers than aircraft flight, since for the insect, the viscosity of the air is much greater relative to its size. That all said, don't treat this as a valid source, it's just what I can remember reading in the past. I'm sure you can find more reliable sources if you search. Graham 00:08, 30 October 2005 (UTC)

[edit] Birds and Flight

Bold textBirds and Flight My science project seemed different in the begining but later changed, and influenced me to begin this. Birds fly using simple aerodynamics, gravity, lift, drag, and thrust. Gravity is what lets the bird come down if wanted. Lift is what helps the bird to lift off, from the ground allowing it to fly, like a plane. This also ties into thrust. Thrust is the bird moving it's wings to provid power to "lift" it off the ground. Finally drag is how much the bird ways. Weight is what holds it back. So it has to overcome gravity and drag to be able ot take off.{| class="wikitable"

[edit] linking to other languages

Hello,

As the links to other languages section seems to be beyond the scope of editing, perhaps this is not the best place to bring this up, but I will anyway.

No, it's easy, you just needed to add a line to the source of the article in fact.WolfKeeper 07:55, 24 November 2006 (UTC)

I noticed there is no link to jp for aerodynamics.(空気力学) I thought this was a bit hard to believe, but in fact, there is no 'aerodynamics' page in Japanese. There is a redirect to the Japanese 'hydrodynamics' page.

流体力学 [1]

Until a Japanese 'aerodynamics' page is created, is it possible to request a ja link that also follows the redirect to the ja hydrodynamics page. Perhaps the ja editors feel that aerodynamics is covered sufficiently under hydrodynamics. I can't comment on the reasoning behind their development.

Thank you for your kindness.

You don't need any special editing powers to do this. Anyway, I've added it for you, I did the obvious thing, and whilst I can't actually read the pages with my current browser settings it seems to have worked. Please confirm this, and by all means correct it if necessary.WolfKeeper 07:53, 24 November 2006 (UTC)

Ok, I see how you did it.

I didn't look far enough into the markup.

Thank you for taking care of it and sorry to

make work for you. Still a bit timid with editing.

The link is correct.

[edit] spelling in continuity assumption

please correct it —Preceding unsigned comment added by 83.3.254.194 (talk) 20:36, 12 September 2007 (UTC)

[edit] Expansion

I'm going to spend some time expanding this page over the next month or so - I've already started with the history section. If anyone wants to help out or has issues/questions, leave them on my talk page. EMBaero 19:01, 30 November 2007 (UTC)EMBaero[[ja:<something>]]

[edit] Gas dynamics

Perhaps all the great information in this article should instead appear in the Gas dynamics page. That way all the pages that link to this article from the word "aerodynamic", could instead link to Gas dynamics. —Preceding unsigned comment added by 24.22.24.208 (talk) 04:56, 17 February 2008 (UTC)
