I have Gas Turbine Third Edition Engineering Handbook
I bought at W & G Foyle one time when I was in London
a few years ago. Pretty good book on the subject.
I was happy to find it.

1000 pages and about $200 bucks U.S.

I was re reading the book and noticed this chart of advances
in Turbine Inlet Temperature since 1950 in the days of
the R3350 Turbo Compound.

If the R3350 could get down to a BSFC of .375 at sea level
with a compression ratio of only 6.5 in 1950 surely a rotary
with twice the kinetic energy in the exhaust and
a compression ratio of 9.6 given the advances in TIT
could do much better.

TIT has gone from 1450 F to 1900 F with air cooled blades
in 55 years. If you steam cool the blades you can go to
2600 F TIT.
