Aero update on RA106

Post

These were shot today at Barcelona testing:

Looks like it diverts air into the sidepods for cooling, although it could be keeping some turbulent air from reaching the rear wing as well.

The Honda did blow up quite spectacularly in Oz, so I wonder if this is a cooling update to solve that problem.
I love to love Senna.

Looks like another version of the "ears" seen on and off the Renault. It does look like getting in & out of the Honda is more difficult though!

Looks like they're having trouble directing air into sidepods :?

interesting...also note that they have 'filleted' the connection between one of the arms from wheel connecting to nose. I thought that this area was abit rough looking to start with anyways. (Not sure if they already had this tho, and not a current update)


BTW, does anybody know what that small eliptical hole right at the tip of the nose is for?? (I think its on the McLaren as well)

It is air intake for cockpit cooling (suspension, steering, electronics and driver).

Actually, the fillet does look like an update. As this was not on the car when it was released.

Honda seem to be working aggressively on the aero. Hopefully they will do something about that awful track rod sticking out. A fairing would clean it up for now at least.

What does Fillet mean? Is it the bodywork going over the rods in the picture?

Simon: [on the phone] John... in the back of the truck you're driving, there's $13 billon dollars worth in gold bullion. I wonder would a deal be out of the question?
John McClane: [on the phone] Yeah, I got a deal for you. Come out from that rock you're hiding under, and I'll drive this truck up your ass.

A fillet is a smooth transition between two angular surfaces. Sometimes it's also called a 'radius'. Here's a pic:

In order for air to flow smoothly around an object there needs to be no sharp 'discontinuities'. This has been done on airplanes for quite awhile where the wing meets the fuselage there is a transition curve. This greatly reduces the drag of the airplane while enhancing the structural stiffness. Same goes for details like the suspension arms mating with the nosecone on race cars.

I wonder if the fillet might be more than just an aero covering as it appears to be a lot thicker in section. It could be an attempt at a revised geometry with shorter length upper arms.

The fillet part is a lot thicker to compared without.

The newer fillet may be thicker, but it is lower drag, and also drastically reduces turbulence. As well, in the picture of the earlier Honda, I doubt they were running with the wheel tether cable. They are definitely required, and usually carried along the upper suspension pieces.

Fillets also further reduce the chance of a crack propogating into the structure.
Bring back wider rear wings, V10s, and tobacco advertisements
