I had this idea for couple of months but since F1 is the last thing on my mind right now I never found the will to present it. Not much of will now, just a simple explanation and sketch to get it off my chest.
I haven't read regulations for 2012, but since turbo chargers as such are allowed, I though of something that could be perhaps potentially better than conventional way.
Here it is:
Turbine (the air compressor) wouldn't be driven via axle of gas turbine, but with mechanical transmission via crankshaft. I had in mind turbo-shaft jet engines and obvious possibility to reduce their rpm to chopper blade rpm, so I reckoned that same thing only in opposite way could be done too. 18.000 rpm to 100.000 rpm or whatever turbo requires.
That means that exhaust gasses would have no obstacle, and the engine would breathe out just as naturally aspirated engine, it would be be much easier to lubricate bearing of compressor since there'd be no such heat, much less weight, better COG etc. Oil tank should be designed differently, but apart from that no other significant changes would be needed.
The roll structure would be as pioneered on MGP 2010, the blade type, with split snorkel. Williams low gearbox would be ideal in case inter-cooler is allowed and needed, so it could be placed on top of such flat gearbox, while turbo could be moved if necessary from front to rear end of the engine.
There you go, have your say. I don't know how often I will be able to come here and reply, so I hope what I wrote and sketched will be enough for understanding.
