Actually Walter, I am not in a position to do anything.
Yessee – I don’t have any of the stuff you’re talkin’ about.
I have a lowly O-320 and that’s it.
But back in the GOD’s (that’s GOOD OLD DAYS), when rEAL pilots flew Allison jet power or JT8D’s or CFM 56’s etc., TIT”S, apart from la femme fatale’s doing cockpit visits, were what you saw going into the turbine, (as in Allisons) and EGT’S were what you saw coming out of the turbine’s as in JT8D’S and CFM 56’S.
As for the rest of the stuff you mentioned, I’ve got no idea what you’re talkin’ about.
See – we Aussies are bloody deep – just ask Grayhawk.
Cheers

Do this. Place a probe 3" from the exhaust flange, then place another one a foot from the exhaust flange (same cylinder with no other exhaust stream joining in). The one further away will read lower. Why? The gas is expanding and cooling as it flows down the pipe. The TIT reading is higher because the TIT is getting more pulses of exhaust gas per 720 cycle. As a result it has less time to cool between hot pulses. It READS higher. It is not actually hotter. You don't really think the gas gets hotter the further it gets from the exhaust valve, do you?
