Did you guys see this yet? The new ImprezaWRC2003. It has a new front end and a new WING. Talk about function over form...hehe

I'm at www.impreza.net forum. There's a lot of Impreza talk over there at the big forum. I'm sure some of you has to be over there..maybe not...

You'll need to watch Speed more often.

A new wing, you say? That thing's not a wing, it's a bloody aeroplane tail!

Got one word: Fantastic.

 

[GilesGuthrie]

it's supposed to be a very trick wing. The vertical fins on the wing are supposed to maintain airflow in the longitudinal axis while the car is going sideways, thus preserving the downforce while the airflow is not optimised.

Ah. Again in English?

J/K. It seems like a very elaborate setup.

Yup, I've seen it. Its so edible...

OK, wings on normal race cars depend upon the airflow being in the longitudinal axis, i.e. from the front of the car to the back of the car.

This is only of limited application to rally cars, since the time that they need the downforce is when they're cornering, which happens to coincide with all the times that they're travelling sideways.

When a rally car is travelling sideways, the airflow is not longitudinal, but is instead lateral, i.e. from side to side, which is no good in a standard wing setup.

Look again at the Impreza's rear wing. You'll see a set of vertical fins. These 'catch' the air that's travelling longitudinally, and will force it over the wing, producing some downforce. This assumes that the car is facing less than 90deg to the direction of travel.

Wait a while, and I'll draw a diagram...

 

[GilesGuthrie]

OK, here we go. It's not the best picture in the world...

The main box is the car, and the front end is labelled. Obviously, the orange shaded area is the wing.

The car is travelling down the screen, but is pointing off to the left.

Now, in order for the wing to produce downforce, the air needs to move diagonally bottom-left to top-right, but the air is actually moving vertically bottom to top.

The wing therefore is not working.

So we introduce fins (represented by the black lines in the orange shaded area), which collect the vertically-moving air, and fire it across the wing in the wing's preferred direction. The effect of the fins is shown by the red arrow.

Does that make sense?

I get it now. Thanks for that, Giles. 👍

But honestly, do you reckon I'm a bit thick? It's no biggie, you were just explaining what I already knew, and it was fairly basic.

Sorry!

No, I don't think you're thick. I like explaining things, and sometimes I go a bit over the top.

No offence...

 

[SandStorm]

Hey, no worries. Thanks for explaining it. 👍

I like to explain things, too. It gives me a feeling that I was meant for something.
