Hi Russell,

I don't know if there is info in this book which is relevant to your
question but I'm sure some of it is relevant to your overall turbine engine
project:

Elements of Gas Turbine Propulsion
by John D. Mattingly

I have a physical copy of it but when I went looking for the exact title
and author's full name (being lazy and not wanting to go and get the book
to read them off it) I found that someone has put a full text copy of the
book online:

https://soaneemrana.org/onewebmedia/ELEMENTS%20OF%20GAS%20TURBINE%20PROPULT=
ION2.pdf

I don't know whether this is legit or not but it could at least serve to
see whether the info is relevant to your work before you decide whether to
purchase a physical copy.
