I must admit that I had to drop out of F1 Aerodynamics school due to my love affair with the uni bars, . . . can any one explain what the big deal is with a zero keel. I would have thought if anything is a good idea. . . more than one team would be doing it??? or is the juice still having its effect on me??
.
The zero keel was used by McLaren in 2005 as well as the Toyota (the TF105B) later in the season. This year both BMW Sauber and Williams have decided to go that way too. I suspect Honda are also using zero keel.
Renault continue with their V keel and Red Bull seem to have followed in the same direction while Ferrari seem to have opted to continue with the single keel (I can't confirm that though).
The keels are used to mount the lower wishbone (the V shaped arm). With the zero keel, the wishbones are mounted straight onto the chassis.
I will try to provide a few photos that illustrate this.
As I understand it, the advantages of one design over another really depends on the whole pacakge at the front but I am not an expert in that area and it would be great if one of our readers can provide us with some details.
