Guy's

I want to tap into the collective knowledge here
My question is, is it possible to mount a turbo in the vertical plane, rather than the normal horizontal? I've never seen it done, but is that cos it don't work??

Cheers,
Steve

Do you mean so that the shaft is vertical?

I'd imagine it would fail very quickly because the shaft is not supported by the bearings and it might mess up the lubrication. Just a guess though.

Not recommended, because the thrust bearing gets excessive pressure by the shaft & wheels, result is 10x shorter lifespan and oil in the intake.

Khal,

I'm starting to become very fond of you , like a father son type deal ,

Ok grass hopper take a look at a few web sites , risingup.com. avweb.com
search there forums look for turbo charged discussions.

Turbo charging owes it's popularity to aviation as a matter of fact 80% +
of technology on auto's is coming from aviation.
and the last time i looked planes do go verical from time to time..

Ohh also most blimps a few years ago where powered by 911T motors complete , the only auto engine I'm aware of that is FAA certified.

Turbos on airplanes are used to provide sea level performance as the plane climbs into less dense (lower pressure) air.

Air pressure at sea level on a standard day is about 15 psi and it decreases about 1 psi per 1000' of elevation. The turbo tries to make up for this.

The ones I have flown do not have a waste gate but have a boost controller lever that looks just like the throttle lever.

You must be pretty old, mate. 'Cause I'm not that young!

Anyways, that's interesting to know. I'm a bit of a 'plane nut from long back. But I never knew they used turbos on the engines!

And cheers Paul, that makes perfect sense. Of course higher pressure would be preferred at increasing altitudes.

Maybe its a deal like everyone knows in the acrobat airplane world
dont use a turbo cause of all the flyin they do leads to premature
failure.
