What if you used the energy of the exhaust to run a turbine wheel

fan engine.)  That would maybe not only create a higher density

atmosphere for combustion (bleed

air form of turbo charging.)  Blow the rest of this air over all the

radiators (oil and coolant)

and collect their heat energy.  Then in a concentric tube with the

exhaust, duct it out the back

directly as thrust and skip the mechanical connection to the engine all

together?  Might be

simpler and easier.  One of the draw backs I can think of would be

fitting it in some where.  Just

remember, if you think it has some merit, you heard it here first!  :-)

Thanks for the wonderful

discussions and forum.  I am also glad to see someone else as interested

in turbo compounding as

me.  Maybe these two attachments will give you some ideas as well.  The

If you want pressure for suppercharging the inlet, then you will also have
heated the air making it useless for cooling radiators. If you just want to
move a large mass of air for cooling (the turbo fan idea) then you need to
gear the turbine down to drive the fan.

If you are going for a gearbox, make Paul's day and feed the HP directly
back into the e shaft.
