Q:
What happened to the wing on the Elise?.......looks like the ends went limp!
Hey I'm getting old . I think it may need that little blue pill............
aka known as a Gurney flap remember it's inverted.......
A:
Nice cars. I love the stratos. Going to look at a 34foot sailboat next week.
A:
Wow, Frank those are some nice cars
Do you still have all of those?
Now I wish I did but you can only have so many toys at one time....
Those little guys bought me my big vertical wing/fluid dynamic super wazoo
Ronin......15 kts feels like 140 going up wind while holding a boat drink in one hand...

Actually the Gurney Flap, "called simply a Gurney or a wickerbill in the US – is ... no more complex than a length of aluminum right-angle rigidly bolted or riveted to a wing's trailing edge". Bold added by me. Note the trailing edge placement. The uprights at the sides of wings are called 'winglets', I think.

The Elise was closest to the Stratos, that's why I had to buy it.......Kool it's all fun.......Ronin...........PS. If you have any questions on her give my a shout I might know a thing or two......Take care..

On the Benetec it is a vertical foil......aka Gurney flap back then . Please do more research.......If you want to bust my hump.

Uh, Gurney flaps run along the trailing edge of a wing...the thingeys on the ends are called end plates and *not* Gurney flaps...often they extend above and below a wing. Dan Gurney first raced 'em and came up with them on his own...but the concept was first found by others (nonracers), separately and long prior.

Dude, I gotta go with Prolene on this one. Not one of the first 150 or so hits (including journal abstracts) on google supports your position.
A:
Yes, I believe he does, but someone said he had a fire and his car was destroyed a short time ago. Now he's taken up playing sax.......the blues.
Ouch...that hurt
That was your cars twin...is she feeling the loss
A:

I'm sorry.....didn't mean to rub it in.
Actually, yes, I thought of that. They were twins and she was saddened by the loss of her sister.....and I feel for your loss also.
You may feel a sadness the next time you see mine, although with new wheels she looks somewhat different now.

Don't worry I am spending my days waiting for the new one

The bottom of the car doesn't act like a wing, actually it is best represented as a duct. The purpose of the diffuser is to reduce the velocity of the air that flows under the car (not to speed up the air), ideally expanding the air back to the pressure before the front of the car.
Okay, I mis-spoke; the diffuser does not "speed up the air". It expands the air volume which in turn lowers the pressure (it does not slow down the air flow significantly either).
It does not reduce the velocity of the air that flows under the car. The air passing under the car is at approximately the same "speed" as the air the passes beside the car. You do not want to reduce the speed of the air exiting from under the rear of the car unless you want to greatly increase the drag (creating a vacuum behind the car is not a good thing). The air expands, reducing the pressure, creating "down force".
And yes, the whole point of the various aerodynamic bits are to "blend" the air flow as smoothly around the car - the less smooth the blending, the more drag is created. The diffuser is simply a clever way to smooth things out while at the same time creating "down force".
Now, do we need to get into the function of the "lip spoiler" at the rear of the clam?
The whole point of my original posts was to point out that "vortexes" under the car are not only what the diffuser is about, they are not a good thing to have in the first place. The strakes (vertical "winglets") are there simply to prevent the higher pressure air from mixing with the lower pressure. No vortexes. And even if there are vortexes, they are not desirable, and definitely are not the purpose of the diffuser.
And I also know that the car is not an upside airfoil - it's just a way to help explain that the same aerodynamics that cause lift on a wing are causing "down force" on the car. There are lot more differences between air craft wings/aerodynamics and automotive aerodynamics, but the basic principles are the same.
Tim, which area of engineering represents the majority of your professional competence?
Some of all of it. Which represents yours? More importantly, exactly why do you have to make personal attacks?
A:
Ronin,
Did you have custom-made brackets made? They look they are steel or aluminum??? Doesn't the wing come with CF brackets?
A:
Don't worry I am spending my days waiting for the new one
.......and what exactly are you waiting for? A new Cayman S?.......a new Z06?.....a new Lada?
A:

Hey Sleepless I thought they were carbon when I ordered it but it came with Aluminum.......I like the way it offsets all the bkack just like the Toybox wheels......So far it seems to work with a 8 degree downward angle....
...Felt very steady at 132 on the GPS......Just installed my Rev carbon seat to make up for the extra ballast I'll be putting in after Thanksgiving....Have a great day...Ronin...

So, is the wing angle adjustable? Easily?
A:

No the angle is set...I'll be making an adjustible mount for it soon....
Any were from 6-14 degrees all depends on the roads I drive . Some canyons max speed 45-90 others 25-125 in the strights.....It does have an effect.....
and now I'll sit back and wait for you know who to say different....
Take care Ronin...

Frank,

Hey jack have they changed the big track it's been 10yrs since I've been there......My best time ever back in 1996 was a 117 in my RS200E.......
If we could setup a session without egos I'd give it a thought........
Hey by the way Tom knows his stuff ..thanks.....Frank
