Harnessing power of a turbo

[jrandol]

On the chat room the other night Lsmith was talking about harnessing the power of 4 turbos ran in series and putting the torque to the ground. Got me thinking... ... ...



What if you ran 4 turbos in series similar on say propane essentially a turbine setup. How could you harness the power of this? 4 large turbos like a HX55 or bigger should put out some serious torque. Any thoughts, i am not a propulsion engineer by any means but this sounds like a fun project to tackle.

This is done with some large stationary and marine diesels where fuel efficiency is critical - it is called turbocompounding. A turbine rotor is placed in the exhaust gas stream after the turbocharger turbine to extract as much of the remaining exhaust gas horsepower as is reasonably possible. The output shaft speed of this turbocompounding turbine is geared down and tied to the engine output shaft to input the additional BHP to the driven load.

Power recovery turbines have been used on large pistion driven Aircraft (B-36 for example) Yes you can get quite a bit of power fromthis system but it is troublesome and complicated.

That's what you said,, but all I heard was...

blah. . blah. . blah. blah... blah. . blah... . blah. . You can get alot of power from this system... blah. . blah. . blah. .

All right guys,, time to goet to work



You could turbo a Honda,, Like this one, and harness the power of the turbo,, just put four turbo's in the exhaust.

if you visit the scania website [www.scania.com i think] they have one inline6 truck engine they make that has the compounding turbo setup. one normal turbo, then the turbine that is geared to the crank. good for like 25hp or something on that model engine

I suppose if you could get ahold of the down wind unit, you could make it work, but I have no clue where you could shoe horn it in at. It would be easy to stuff it in where the starter is at, but that creates a whole new load of problems.

hmmm..... I would like to build an ultralight aircraft and was trying to rack my brain on how I could make turboprop setup with some big honking turbos. any ideas and ways to keep it light?
