Turbocharger assisted Aerodynamics in 2014 and beyond

[PlatinumZealot]

In the 2014 season we will have precious, pressurized air from the turbochargers to do our evil deeds of cheating the rule system.

Can you say off throttle blowing of wings? Or on-throttle wing stalling? Compressed air brake and wheels cooling?

The Lotus DRD is a prime candidate for making use of compressed air from the turbo charger.

Lets see some designs folks!

Is it mandatory that air inlet shoud happen from the conventional roll-hoop position? If not, one could explore useful interactions given that a turbo can suck air in, at a slightly lower efficiency cost compared to NA engines (maybe I am wrong in assuming this - if so, please correct me)

Benetton b188 it is just an example - we can maybe see weirder air inlet positions.

i have read somewhere that exhaust blowing will be less interesting because of the lower exhaust energy content

5.14 Engine intake air :
5.14.1 With the exception of incidental leakage through joints or cooling ducts in the inlet system
(either into or out of the system), all air entering the engine must enter the bodywork through
a maximum of two inlets which are located :
a) Between the front of the cockpit entry template and a point 500mm forward of the rear
wheel centre line longitudinally.
b) No less than 200mm above the reference plane vertically.
c) On vertical cross-sections normal to the car centre line.
Furthermore, any such inlets must be visible in their entirety when viewed from the front of
the car and without the driver seated in the car.

Too obvious - top spots already banned...
But still some weird possibilities are open maybe

5.8.1 With the exception of incidental leakage through joints (either into or out of the system), all (and only) the fluids entering the compressor inlet must exit from the engine exhaust system.

Cannot use the air from the compressor for aerodynamic purposes.

[Shaddock]

They must be exiting the air from the DV/blow off valve into the exhaust system if this is the case.

If they have them at all.

Is there any part of the car that isn't specified by exact rules and measurements?

The money, but they are working on it.

[shelly]

The b188 position is ok with the rules - for example it would open to interesting interactions with the winglets used this year on top of the sidepods' leading edge

[BorisTheBlade]

But only if the winglets aren't in front of them.
I wonder if something like a monkey seat placed above and right in front of such an entry would benefit from the suction.

hmmm

[ringo]

well those res say all air going into the engine.
It doesn't say all compressor air must go into the engine does it?

Those are rules for inlets, not outlets.

All fluids leaving compressor must exit the exhaust. That means the only place you could squirt compressed air is in the engine or straight out the exhaust. I don't think it gets much clearer in FIA terms.

[shelly]

From compressor straight out to the exhaust could be an option maybe
