Lotus E22 Renault

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

No, it works the other way around, the rear wing is influencing the gas flow. A simple look at the exhaust position will show that it is way too far backwards and not at a sufficient enough angle to actually influence the rear wing.

What you are seeing in the Sauber image is the gas flow expanding and pulled upwards by the low pressure of the rear wing, nothing more, nothing less.

The low pressure behind the rear wing does pull the exhaust flow upwards, but the exhaust is in itself a low pressure flow. So pulling that flow up also pulls air from the diffuser zone; which is also a low pressure zone, so you could describe it as working the other direction as well. So I believe Turbo is correct in that it all works together.

Assuming it's working. The idea is to prevent as best you can the air coming from over the side pods from essentially splitting this low pressure area in two.

That's my understanding, at least.

Except that the exhaust gasses energizes the airflow underneath the rear wing, accelerating it and dropping pressure even further. That is very important infact.

It's like pup said; it works as a stepping stone between the diffuser and the rear wing.

And even more it hepls attach the flow and sets the stall point higher on the latter... Even if we add monkey seat you get preatty neat way how control rear dowforce (rear wing and dififfuzor) in low and hight speed corners.

Yeah, looks like the lower rear part of the gearbox is almost floating over the floor and the diffuser. The bodywork under it looks extremley thin and short.

I'll be surprised if this nose doesn't create a bottleneck of turbulent air between the tusks when the car is in yaw.

Seems logical.
But according to AMuS, their developping an even more extreme version fo this nose which has much longer tusks/a much shorter crash strcuture in front of the bulkhead :!:

What's that outlet 'chimney' above the exhaust hole for? I'm sorry if this question has already been answered but I can't seem to find it back in this topic, maybe I'm unable to find it back because I don't know the proper terminology for it.
