Hi y'all. I've finally been ignorant long enough to motivate myself
to solve that. What do I want to know? I want to know how jet engines
work. I want to know how they're built, designed, and run. What kind
of service they require. How they're operated.

What the history of jet engines are, from the first turbojets to
the latest high-bypass fans. Or even to the latest mach-busting
low-bypass turbofans. How do you hook up a propeller and get a
turboprop?

I've worked with piston engines hands on and "on the drawing
board." I could take apart and reubild a good '50s chevy engine.
The Lycoming in the Mooney is really straightforward. I could
probably be the "Connecticut Yankee in King Arthur's Court" for
piston engines. (Helps that I fly out of CT!)

Can anyone recommend a good book, or books, about the history and
operation of jet engines? It can assume a modicum of technical
knowledge, or not. But it has to go beyond the "hey, it's a
compressor then a combustion chamber then a turbine, etc."

Mail responses would be appreciated. I'll summarize if there is
interest.

Thanks in advance,

Doug

PS: I crosspost to IFR because I'd imagine many instrument
rated pilots have flown or fly turboprops or jets. I post to
military sinc it seems all military aircraft are jets.

a free turbine engine [eg pt6].  There's what looks suspiciously
like an automotive torque converter between the turbine and the
[reduction] gearbox which the prop bolts onto.  First time you
see a mechanic grab a prop on one of these [after the turbine is
shut down, natch] your heart may stop momentarily :>

  Actually, a common hot-section test on a PT-6 is to hold the
  prop stationary with your hand and advance the power...

Only if your jet engine has 12 or more cylinders and a supercharger.
