Boeing 747 Wing Tip Vortex Test

This 36 second movie clip shows the Boeing 747 Wing Tip Vortex Test.

As part of the overall National Aeronautics and Space Administration (NASA) study of trailing vortices -- the invisible flow of spiraling air that trails from the wings of large aircraft and can "upset" smaller aircraft flying behind -- the NASA Flight Research Center (FRC) borrowed a Boeing 747 jetliner for testing. The B-747 had been purchased by NASA for the space shuttle program and assigned to the Johnson Space Center. Six smoke generators were installed under the wings of the B-747 to provide a visual image of the trailing vortices.

hey! the place they're at looks like where they shot the first moon landing =P... lol just kidding

The smoke here is generated just so that the vortices may be visible. Any airfoil producing lift will create a vortex about it's tip. High pressure air escapes around the tip to rejoin low pressure air above. Because air is fluid, it drags more air with it, as it does. This creates a vortex that grows and slowly dissipates, after the wing has passed. Very dangerous. Some runways are closed for FOD runs, after extremely large aircraft use them.

@Nukefuzion its just stupid to bring up even though he was kidding

@rallycar757 It's funny to make fun of people who are funny...

You couldn't tell d2 was joking by the "lol just kidding" -_-?

[rallycar757]

@Dusty594ok but its not cool to dothat since some people dont believe we did that

[Dusty594]

@rallycar757 Seriously... 3 years ago and you reply to it? and again... seriously, I said I was just kidding. I know we landed on the moon, You can still see the site where they landed... (I believe they set up reflectors?)

@d2kool594 no one cares if you think that we didnt land on the mooon, give it up we did

[SergeantZippo]

That looks alot like Edwards, CA!

Its great to visualize this rather than just seeing it as numbers and symbols on a page !

@MikeyyG1 wow.. a comment i made 2 years ago just got commented on O.o? lol

[MikeyyG1]

haha funni you :D naaaaaat
