Williams FW36 Mercedes

[beelsebob]

How on earth are Williams able to achieve the cooling requirements of these power units, when they have no visibly large hot air outlet compared to every other mercedes powered cars, including mercedes themselves who would have known the cooling requirements for this engine long before customer teams, yet still have substantially large hot air outlets hidden between the suspension arms. Does anyone know the radiator layout Williams use, as even in previous years they have never ran with a large cooling outlet when the likes of Red bull with the same Renault engine always had a huge opening at the rear of the engine cover.

What on earth do you mean? There's a huge cooling hole at the back all around the gearbox.

And This

I wouldn't class the Williams arrangement as a "huge cooling hole" when IN COMPARISON to McLaren and Mercedes! If you also look back the last year Williams never really had much of a cooling outlet IN COMPARISON to other teams with the same engine

No, just as last year, the Williams simply has a different shape of cooling outlet. The area around the large hole in the back of the body work is easily as large as the directed outputs Mercedes and McLaren have.

Yes, instead of having a funnel or sidepod extensions to let the air out, Williams simply cuts off the body and let's the air escape there.

As a result there's less of a bulge, but a pretty big exit still.

Cooling outlet that was copied in the latest Ferrari update.

I personally find the solution for the cooling air outlet, as the best in the formula 1 A very low fluidic turbulence and a very good hot air inflow at the monkey seat.

[ringo]

the weakness with the williams cooling outlet is that it has a longer portion of bodywor ahead of the diffuser tail with low quality air flow, though it may be hot.
The other teams have extended their cooling ducts to as far back as possible to have more controlled flow over as much of the length of the car as possible.
A good upgrade for this cart is to have the ducts/skirts extended to to the diffuser just as the other cars.

Argh, why on earth would you make such a wild assumption?

Do you think Williams is so dumb that they haven't tested a solution like that in CFD and the wind tunnel at some point over the last 3 years? Or have they stuck with the same layout at the rear just to allow armchair aerodynamicists to tell them what they should be doing?

Considering ringo's comment, b-bob please explain why then does Williams rear end look like such a hack job compared to the coke bottles, ellipses, tucked in, tidy, clean, and any other ways to describe the back end of these cars.

My assumption is the cost vs gain isn't enough and looking back a few pages around Spanish gp the black cover over the gear box could be changed quickly easing the repair time and also could test several different covers with out having to change entire rear bodywork.

I don't know, I'm not a williams engineer, and I don't have the aero simulations. It's clear though that an entire team of engineers thinks that this is the best solution available to them right now though.

The fact that you've seen a cover over it tells you that it's nothing to do with cost. The team already ate the cost of designing and producing a cover over this part, and it clearly didn't perform as well. They simply have a different philosophy from the other teams.

Williams are smarter than the armchair aero guys but are pretty dumb in comparison to other f1 engineers looking at the results of the last few years, they are even being beaten on a regular basis by a Force India

[rich1701]

I'd say Williams have gained a huge performance swing over the winter in comparison to last year. The car is better than the force India marginally and they have over taken Mclaren. That is an incredible achievement for the Williams engineers, let's not forget this. What irritates me is they have totally failed to get the best out of their car. The race team itself is failing.

the Thing from Brixworth

[hardingfv32]

1) Do you think that the tail pipe must be assemble with the transaxle?

2) What is the external device around the tail pipe?
