Mercedes AMG F1 W05

new sidepod arrangement which brings the cooling outlets further outboard.

From this shot it looks like that is being blown directly on to the suspension arm.

You know, some people here in Jerez should better get informed first before tweeting. The front wing was lying on the straight as an entire piece, with just part of the pylons attached. There was no doubt it was a front wing failure, much before the team confirmed it.

Rival publications no doubt!

Did Mercedes bring a spare front wing and will they run again today?

There's a lot of damage to the car. They probably will not run anymore.

don't think they'll run today, no. i hope the tub isn't damaged, but looking at the actual nose still being in one piece it's safe to assume it isn't. the front suspension took a beating though, so they'll have to fix that. these parts thankfully are more or less 'easy' replaceble so that isn't the biggest concern.

the question is, will they have sufficient spare parts. i think they will because i do imagine every team to expect possibile crashing scenes. they'll however check the internals of the car too because the abrupt stop might have an undesired effect to other internal parts. that might take more time, even though a system check might tell them a lot too.

If those are the only cooling outlets, then surely a huge load of heat has to exit through those. Looks perfect for sealing the diffuser.

No. Cooling air is in no way good to use as a seal. It is dirty air that went through drag inducing radiators. Just because it has a slightly higher temperature than the ambient temperature, does not make it useful or better than normal air.

@Turbo so what do you reckon to the suspension being so close to the sidepod exit?

I dont think any hot air is being forced out so to speak, more vented than anything. Speculative.
We have seen merc use louvres in the past but maybe in this formula it is better to direct the weaker flow in board.
Could just be additional cooling for the engine/turbo/battery.

@Wesley I think he meant a cooling vent with Hot air coming out of it...

They could accelerate and smoothen the air intenally before ejecting it. Difficult to tell, but they do want that air somewhere specifically.

On the nose failure: if only the pylons gave way, then it's just an issue of reinforcing them. Not difficult to do, and can probably be done overnight.
It's getting problematic when it's the nose that failed. That means reinforcing it and again crashtesting it.

That is also possible. It's just speculating at this point until we have better pictures.

A bit of armchair-aero for you:
- Rather than for sealing, couldn't /shouldn't hot air be useful for reducing drag along the bodywork?
- It's less viscous, so couldn't it reduce friction, or would it just cock up the attachment of laminar flow of ambient air?

seems different side pod configuration near end

bigger cooling outlet it seems

some comparison mercedes w05 with w04

[dren]

They are exiting the hot air in a place that doesn't have a huge effect on the rear of the car, and also likely a place that works well with the radiators and internal flow. They exited the cooling flow in roughly the same place last year. None of the teams have massive cut-outs by the rear tires and diffuser, so none of the teams are "blowing" anything.

Some very interesting developments on this car:

The front lower A-arms are almost one straight arm
An interesting starter motor hole
Small sidepod openings, exits and overall pods themselves
Very tight engine cover
Rear crash structure sides go straight to the diffuser top, very clean rear
Drive shaft suspension arm retained
Rear wing looks less draggy than in past - cut outs and less AofA

The rear wing endplate attachment to the diffuser top runs along the floor to the strake by the wheel. This keeps the diffuser top flow separated from the flow between the strake and rear tire/brake ducts.

[monsi]

Are they just keeping moving suspension parts out of the way of the main air flow ?

[clipsy1H]

the shape of the nose looks like W01. i think sidepods are to small. TBH i don't know how those cars can eliminate the heat from engine !!

Will Lewis comeback on track ??
