Two Turbines into one exhaust
Question, has anyone run two turbines into one exhaust?
Basically a bifurcated pipe in reverse, obviously with a larger outlet diameter,
This is for a large potential project where as you have the additional safety of a twin setup yet in a model with a single exhaust.

Thanks for the replies, yes I have seen the two exhaust setup on the big 104's.
Just wondering if you could port both exhausts into the same exit, not two separate ones.

Unless you can guarantee both turbines throttle exactly the same time I think you will have issues with the lead turbine ‘sucking’ on the slower one and that’s if the turbulence didn’t make a horrible sound.
I think you would get more thrust out of the split exit set up too.

Yep that is exactly what I was worried about, basically a pressure differential and not sure where it could affect flows.

I’ll see if I can find the article in an old JetPower on the F-16, I still thought the big pipe was divided.
Pete’s Havoc with the long inlet joining tubes I can see how that worked. So I guess it goes back to the OP and whether he has the big fat fuselage space to do the same.

Yep pretty cavernous space in the fuse so that is not the issue.
As said this a potential project, I have two on the cards as a next build project both with their quirks not sure which way I will go yet.
Thanks for the input.
