Yep, the individually wired theromcouples are sent to a Totalizer, when
they
are not wired in series. That is why the datum is a total.

Yeah, OK, so in Tarverworld the temperature of the gas
entering the turbine is around 18,000 degrees C.

What is you post supposed to mean, Rick?

Did you just want to make something up and look stupid?


Tarver, why not? You do it all the time.

Lockheed has used some version/model of the Allison T-56 since "1956" on
all
C-130 models. Yes it is called a Allison T-56 because it was a "56 model
Allison Turbine Engine". The same year the C-130 first flew at/from
Marietta, Ga.

There have been numerous improvements made to this basic engine design
over
the years to incorporate new technology, increase power, etc., but the
basic
design remains the same.

The "T 56-15 Model Allison Engine" referred to by Phil, means a Allison
T-56
engine incorporating the 15 th update.

Check the model # of the Allison T-56 engine used on the C-130J. If you do
a
little checking, you will find the T-56-15 engine was used on late C130 E
&
G models.

Tarver you claim to be an "Electrical Engineer". Don't you know better
than
to argue with a person quoting the manual on a given/specified item?
Apparently not.

Actually, the J has the AE2100D3 engine. The T56 production line was shut
down shortly after the J went into production.

Roughly the surface temperature of a Class B star. Considering titanium
boils at 3,278C, could this be ... magic metallurgy? g, d & r

It does seem a bit warm for a turbine but Tarver says the
thermocouples are wired in series so that they add up to the
"total inlet temperature." And Tarver couldn't be wrong
could he?

Here we see how Rick has the reading and comprehension skills of an
elementary school student. Why would you think that adding the signals from
thermocouples in series would add the temperature?

How do you survive in this world, Rick?

Hey, Splaps. Next time you are ever near a DADC or it's diagram,
check out what they have at the other end of the tubing connected
to the fitting labeled *TOTAL*. Only ONE pitot tube!

Yep, the term Total means they added two sensors.

Catch this, Jimmy:

Since you started your childishness, you have trolled up three different
groups, with pretty much the same results.

Do you remember that old Gulf Aero DER that hung around in the pilot's
groups? Well, he read your stuff and got so stupid they fired him.

Next some poor tech at BF Goodrich got trolled up and removed the
temperature probe from the HS-125 700 ADC-80 changes. That cost them
hundreds of thousands of dollars in customer relations money.

And third, but not least, you trolled up Dudley and Shafer. Well wouldn't
you know, once Dudley got a conspiracy going with Mary's friends at Dryden,
the system **** out the two civil service slots and told Dryden to create a
basis for their funding. Well you know, those Dryden folks knew full well
they were making a living off someone else's past, but they hadn't realized
some of the people's work they made their living off of were contemporaries.
So old Ken Peterson, a personal friend of Dudley's, sat about and did not
create any basis, so now they have lost 1/3 of their budget. (ie $40million)

So, Jimmy, when I call your work an idiot detector, I really mean it.

Your's is a much nicer archive troll, as Miller is completely clueless about
the subject.

On every aircraft I ever worked on thermocouples were in parallel if there
were
two or more.

What engine shop did you work in, Dan?

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

Yep.

I ask because I came across an interesting paragraph in the
T56-A-15 service manual yesterday. Went like this...

...measures the turbine inlet temperature by means of
thermocouples...Eighteen thermocouple assemblies are mounted in the
turbine inlet casing of each engine...One thermocouple of each
assembly is connected to the turbine inlet temperature indicating
system, and...one...is connected to the electronic datum control
system. The 18 indicating system thermocouples are connected in
parallel [!!] by the indicator turbine thermocouple harness
assembly,

I'm surprised you ever doubted the truth on this one!


So, let's revise.

That's going a bit too far... Nobody can revise the Tarver
Chronicles! :-)


bimetallic thermocouples generate millivolt signals,and paralleling
them would not work.Standard practice is to series-connect them,and
compare to a reference junction.Do these assemblies include signal
processing to convert the mV signal to a digital form,which could then
be sent on a parallel bus?

Well,I guess they aren't bimetallic thermocouples,then.
Anyone have any speculation on what sort of signal will work with a
parallel connection?

You can go back to sleep now.

Well,that was an informative post.Best you could do,I suppose.

Same for any MM, the data does not need to be accurate.

grief !
so if that were the case, then a generic manual would suffice.
heck ! why bother, why not use the manual for a 1957 ford zeypher instead


Any engine temperature station using more than one probe is a Total.

That is how it works.
