Hercules Engines

Hey Splappy,

Do you remember this series of pronouncements;

Not really. On the T56 engine TIT = (T)urbine (I)nlet (T)empreture.

Yes really, on every jet engine TIT is Total Inlet Temperature.

The name refers to the fact that it is an average across several
thermocouples.

You appear to be terribly confused with thermocouple connections ...
thermocouples are not wired in series.

Yes Rick, the thermocouples at the turbine inlet are connected in
series.

Total inlet temperature is what it is and will not change
with anyting other than altitude, speed, and OAT. TIT will not effect
compressor inlet temperature.

What does that have to do with anything Rick?

The fuel control will use compressor inlet temp as an input to determine
the fuel flow needed to produce a gross power output and then the pilot
or in the TD system, a modulating valve will adjust TIT Turbine Inlet
Temperature to the desired level.

No Ricky, the fuel controller uses pressure one and temperature zero,
from the pitot tube, to adjust fuel flow.

Even us pilots understand that stuff ...

Not a chance of that Rick.

several others are attempting
to help you with terminology, accept that help graciously or you will
continue to dig yourself into a hole.

You are a ****ing moron Rick, stick with pure ****ing magic, 'cause you
know nothing about aircraft systems.

Tsk, tsk, tsk ... sticks and stones and all that but for averaging,
themocouples are wired in parallel.

No way, that would be stupid.

Turbine Inlet Temperature is jsut what it says it is. On the T-56 it is
obtained by averaging the output of 18 thermocouples wired in parallel

That is a lot of wire, perhaps you would like to rethink your rediculess
assertion.

and eve though they are as wrong as the rest of us in this thread, the
Air Force, Rolls Royce, Allison, and even the Navy refer to T-5 as
TURBINE INLET TEMPERATURE.

That is fine for the PFM crowd, but quite incorrect.

Have a really nice day.

I am.

Hmmmm...want to change your mind? This is your opportunity to prove all
us chooks wrong by showing that you can admit when you're wrong. Give it
a go.

Great Tarverisms #4

The pitot tube was added to the first American jets to prevent the
kind of failures that killed an entire squadron off Florida. Without
P1 and T0 a jet will stall in fog.

Thanks to both of you for playing.
