I agreed as well. Wondered how many teams will starting copying the designs or try similar concepts in coming test days.silversurf3r wrote:+1amouzouris wrote:i think that mclaren are not only blowing the brake duct fins..but they are also going to try seal the diffuser..or at least blow over it..
Judging by their current less intricate brake ducts.
But that's impossible to police. You could look at the McLaren and the Ferarri and go "well, you're exhaust exits are where they are in order to do a) and b)" and they would say "no they are for c) and d) and they just happen to do a) and b) too, how fortunate.".Gridlock wrote:Any speculation about trying to use the exhausts to seal the diffuser goes 100% against what e.g. James Allison has said about Charlie being very careful to implement the spirit of the "exhaust gas aero benefits must be incidental and not designed"
No mass flow increase but an increase in the viscosity of the air as it is heated by the components inside the chassis, this increases it's pressure. This also creates drag, if you could cool this air, you would reduce drag across the board. Among other things that can be done.ringo wrote: No you cannot look at it like that. It is not a rocket. It's a simple heat exchange with conservation of mass. What enters the radiator inlet is what exits at the back.
What enters the engine inlet is what exits through the tail pipes with the addition of fuel mass.
There is no increase in mass flow.
Presumably one could make the same argument against those teams that have covered their beam wings in temp tape. Why do so unless you're trying to see whether the wing is being blown...? The response "it's by accident" is no more a valid excuse than it is for any other sort of exhaust blowing these days e.g. McLaren's.Gridlock wrote:By having a benevolent dictator, of course. Charlie's word is final.
If your car's floor is hot enough to cook eggs on when the rule says exhausts must point upwards and backwards, good luck arguing it's not by design.
Yes, the airflow going over the downward surfaced sidepots, is able to enter the slot , as a jet stream, pushing the exhaust gas down.KeiKo403 wrote:Are these not just tyre marbles?
I know they normally fly off backwards but it doesn't make sense that they can burn the floor so close to the exhaust exits.
The car is travelling very fast going forwards, the exhaust gasses are going very fast travelling backwards. Those 2 speeds combined together would be very fast indeed.
My question is, is it possible to go from exiting exhaust gasses pointing 10 degrees upwards to blow practically 90 degrees downwards within 350-450mm.
Make sense??

I'm afraid they've shown their hand too early. They should've been more cautious and added extra heat shielding on their floor, shots of their floor section between exhaust exit and the rear wheel are very revealing.
I'm not an aerodynamicist, so mine definitely wouldn't be an educated guess, but if you look at where they were blowing the exhaust last year, it seems like they're trying to achieve the same effect.Shakeman wrote:

Remember how fickle the FIA is.It has passed not a month since Lotus' front suspension solution was given the thumbs up by Charlie and then overturned by the FIA.Shakeman wrote: They might have been surprised by how effective the down wash was. That's what I'd be saying!
Before you're too critical of McLaren's approaches how would you argue that other team's exhaust position does not influence aerodynamics? The RB is aiming at their suspension parts and beam wing.
From what I've read on other forums and on twitter the McLaren and Ferrari exhausts have been declared legal, is this not the case?
