Aston Martin AMR26

That nose and wing connection look so funky... The top plane, the movable one, looks like it's touching the bottom of the nose in the middle...

Using the flow through the intercooler to feed the turbo?

Would that not just heat the intake air at the same time as cooling the compressed air?

The flow rate would be pretty poor if you combine the inertcooler and intake, you'd have the air filter restricting the cooling flow as well.

Much easier to split the intake IMO.

Never mind being easier, it would not make any sense to draw the intake air in via cooling the intercooler first as you would be heating the air going to the turbo before heating it further in the turbo and then trying to cool it by transferring heat to the air going to the turbo.

[Martin Keene]

The wiring harness is in the way for a proper look, but do you think that is a straight connection from charge cooler to inlet manifold?

In which case, as the airbox does not appear to be spilt into different sections, where is the turbo being fed from.

Look closer!

at what!

Scarbs already highlighted it.

I am not on the toxic cess pit that is Twitter, that confirms the air from the turbo is what I thought it was, but does not explain how the air gets to the turbo, in fact if anything confirms the air for the turbo is not coming from the airbox.

You should at least see the thumbnail now. As I understand it, air to the turbo comes from the sidepod.

There is a horizontal element just visible within the through the roll hoop (inside the airbox). This probably indicates that the ‘snorkel’ is diverted into two separate feeds, the upper to the intercooler and the lower to the turbo feed (within the V).
What these images do not show is how the intercooler is vented back to atmosphere, hence my earlier preposterous suggestion that the used cooling air is potentially feeding the turbo inlet.

If your primary concern is is packaging and drag reduction if you really want to minimise the effect on drag of the cooling package why not feed the turbo like this? The split in the snorkel diverts some (50%-ish) ambient air directly to the turbo inlet area, the other 50% goes through the intercooler and is then reintroduced to the ambient air on the other side of the intercooler (which will be subject to a cooling effect as it mixes with the ambient air). The turbo creates a massive low pressure zone in this plenum, having a massive impact on the efficiency of the cooler. The waste air is then ingested by the ICE and doesn’t need to be vented through the bodywork.

I’m not saying that this is an ideal case, but we all know that aero is king and if the trade off in power is more than balanced by the aero efficiency of the whole system, why not do it (or at least try it)?

[astracrazy]

From the flowviz above, I am amazed there is no sign of flow from the front wing even going near the sidepod intakes.

Looks like it goes under. Extended bottom lip of the intake doing its job?

It's difficult to imagine that those suspension mounting points have enough mechanical strength. There's nothing between them to give mechanical strength laterally.

The Aston Martin has a working front wing active aero. It was just shown on the broadcast into T1. It works.

Any video of it? On the F1 channel they only showed the car from behind in straight line mode.

I think that is the most likely explanation, and we just can't see the feed to the turbo because it is going down under the intercooler very early.



A wild thought occurred to me last night while in the gym. Most teams seem to be trying to push the front tyre wake outboard using the floor boards and side pods, yet Aston have basically an open channel from the front of the side pod to the diffuser with apparently very little obvious means of controlling front tyre wake, with the exception of the floor board, and I can't believe that is sufficient to manage all the tyre wake.

They then have the rear wishbone inner mounting point mounted *very* high, this being a Newey car is only going to be for aero reasons, that coupled with the lack of a beam wing of any significance, do we think it is possible that he has found a way to pull in all the front tyre wake inboard, align with with the wishbone and use it to energise the diffuser?

[Emag]

You cant use the tire wake to energize anything. It's very messy turbulence. If anything, if you bring it towards the diffuser you risk stalling it.

[Martin Keene]

That is true, but if you could some how align it and direct it under the sidepod and the wishbone?

Like I said, wild idea. But I am trying to work out what the side pod and wishbone are doing.

[mzso]

Seems to be air to air intercooler like Red Bull

Seems to have a "sleeve" thermal barrier on exhaust tail pipe, you can see the beginning of it aft of where the waste gate outlet joins main exhaust.

That's for you to look at mzso

Well, since it goes all the way, it's seems to have been a shadow on the sleeve.
Rather than a something going " from a matt black sort of colour to the shiny-ish colour of the tail pipe."
So everyone was right, right?

Let's not assume that this is the "final" version of their sidepod or aero in general.
Suspension and cockpit are usually the final version or a close one at this stage, but other easier to change aero might change around them a lot till Melbourne.
