Golf Balls

[oz]

A Golf Ball travels further than an equivelent ball of the same construction and size because of the dimples sticking the air to the surface of the ball,although difficult to reproduce the same kind of dimple over a large area would this work on fairings/streamlining/frame surface preperations as in rippled paint finishes?

i think the dimples in a golf ball work because of the backward spin --you would get pretty dizzy if your car did that    willie buchta

We actually talked one time about building a body that had a golf ball surface all over it.  Our first thought was several ball peen hammers.  Then maybe a golf ball manufacturer could make us a cover for the body.  We finally gave up.  I still think that it would work.  Brian #7796

Here's another one of those subjects that comes up every year or two on landracing.com.  Six or seven years ago Vetter had a bike at Bonneville with dimples all over the rear of the fairing -- might have been on the front, too, but I don't remember.  No, I don't have any data nor run speeds -- but I remember seeing the odd appearance and paying enough attention to bring it to mind when I read these posts.  Maybe someone else has more information.

That was my idea!!!

here from the DLRA message board when somebody offerd up a Ford sedan body with hail damage for sale I give you the Dr Goggles Dimple-o-matic car treatment.....

Here's a question for the Aero literati:
Will the hail damage act the same as the dimpling on a golf ball and promote the laminar adhesion of air over the body thereby allowing an increased speed?
Is this cheating or Act of God?

Dunno Lynchy but I'm gonna bring a little ball-pein hammer to the lake next year in case it catches on , I hereby offer my services to "aero-dimple" any car for a cold six pack .

Surely Jack has built a golf-ball body and had it rolled down his famous hill.

Look at this stuff, somewhat the same principal and no you down want dimples on the front.........

.................... Sealing Tapes and Control Seals along with Zig-Zag Turbulator and Dimple Turbulator Tapes (also called trip tapes -- "they create a rough place for the laminar flow to "trip over" into minor turbulence before separation occurs due to body shape. This reduces drag because this turbulence keeps the flowing air closer to the body than if it wasn't there, therefore reducing profile drag.", the Rev. H+.

I am currently experimenting with riblets for the "future" project.

Ifnitain't ona glider plane, I don't want one.
My "World Speed Record" for a bowling ball down the face of Hoover Dam from 66 is still good, in part because of the newly added security. 8-)

I seem to be testing the "dimple theory".  Every year new dents are appearing on my Stude's body, and I am also trying the "reverse dimple theory" where the rust is bulging the paint out..........

if you are constantly running 1 mph off of a record and exhausted all of the HP you have ... "THEN" start looking at this voodoo.... design and build your body "correctly" in the first place... all that crap works in theory and in wind tunnels but fails to deliver in the real world.... to add some dolaneese.... "a fool and his money are soon parted"

so thats why Dolan showed up at the NW Reunion sans tux and shoes..............

i am running naked but have seen a nice rippled paint finish for the frame just thought i would run it by you guys if anyone has any tips on voodoo i am willing to learn that too amazing how much i have learned from this site already maybe thats one for another topic !

Bonneville doesn't have a putting green, it's a putting white and you need orange balls or you loose them and there would be balls everywhere. This subject has been discussed before under the  DIMPLE theory..
It's somewhere in the archives.
