[edit] article inconsistancy

The article states that: "Fluids naturally flow from low to high pressure and the relatively high pressure air below the wing has a natural tendancy to flow to the top of the wing." Isn't the one sentence contrary to the other? I was wondering which is true! Does air flow from low to high pressure or the opposite?

Thanks for finding that mistake! I've changed the article with the correct info (they flow from high to low pressure). -Lommer | ^talk 03:37, 25 Jan 2005 (UTC)

[edit] Merge proposal

Wingtip vortices and wake turbulence are distinct enough phenomena in my (currently winding down an advanced fluid mechanics course) opinion that they deserve discrete articles.

I agree, the reason I put up the merge tag is that theres a lot of info in wake turbulence that is duplicated here, and there's a lot that belongs here and not there. The wake tubulence article should still exist, but it doesn't need to cover wingtip vortices in detail; that's what this article is for. -Lommer | ^talk 23:47, 21 August 2005 (UTC)

I've undone a poor attempt at a merge that resulted in something even worse. I've maintained the wake turb-only aspects at that page, and removed duplicated information and wintip-vortex-specific info to here. -Lommer | ^talk 23:31, 31 October 2005 (UTC)

[edit] misleading statement about proportionality

"Since the size and power of wingtip vortices are directly proportional to the size and speed of an aircraft..." ...better write proportional to V^2 instead of speed (cause Lift~bound circulation and lift ~V^2 and trailing circulation is deviation of bound circulation and for this article it should be assumed that all trailing circulation is rolled up into wingtip vortices)for those who are not common with aerodynamics

[edit] Misplaced Picture

Regarding the picture entitled "F/A-18F showing vapor cloud over its wings".

Although this is a fascinating picture it doses not show any formation of tip vortices. It does however illustrate that lift is produced by low pressure on the wing top with can be seen in certain atmospheric conditions. I therefore suggest it is moved to the section describing lift.

[edit] WikiProject class rating

This article was automatically assessed because at least one WikiProject had rated the article as start, and the rating on other projects was brought up to start class. BetacommandBot 10:06, 10 November 2007 (UTC)

[edit] Regarding Title Picture

The description for the F15E picture is rather misleading, the picture more accurately depict aerodynamic condensation trails. —Preceding unsigned comment added by 76.91.58.173 (talk) 19:27, 26 May 2008 (UTC)
