Hi all and Happy Thanksgiving,

Does anyone have an authoritative source of information on pipe specs vs turbine class? I am thinking inlet and outlet diameter vs. thrust, wall thickness vs. diameter and thrust, benefits of taper from inlet to outlet, gap from exhaust cone to bellmouth, impact of pipe length on the other dimensions, etc.

At the moment I am mostly interested in pipe specs appropriate for 300 N-class motors, with an eye on appropriate inner pipe diameter and wall thickness. A few examples of working setups for this size motor would be great.

In the post-Tam world the prior algorithm ("just ask Tam") is not working anymore :-(

I am thinking we have at least tribal knowledge on this, perhaps there are other sources of expertise available?

thanks for any info

Dave
