Hercules Engines
Hey Splappy, Do you remember this series of pronouncements; From: "Tarver Engineering" Newsgroups: rec.aviation.military Subject: Do Hercules military aircraft use the same fuel as civilian aircraft? Date: Fri, 8 Nov 2002 19:19:37 -0800 snip wrote in message 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. John P. Tarver, MS/PE USAF jet engine mechanic '74-'80 And; From: "Tarver Engineering" Newsgroups: rec.aviation.military Subject: Do Hercules military aircraft use the same fuel as civilian aircraft? Date: Sun, 10 Nov 2002 10:32:29 -0800 snip "Rick" wrote in message ... 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. snip 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. John P. Tarver, MS/PE USAF jet engine mechanic '74-'80 And; From: "Tarver Engineering" Newsgroups: rec.aviation.military Subject: Do Hercules military aircraft use the same fuel as civilian aircraft? Date: Sun, 10 Nov 2002 12:21:32 -0800 "Rick" wrote in message ... "You are a ****ing moron Rick," 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. snip Have a really nice day. I am. John P. Tarver, MS/PE 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. Phil -- 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. John rec.aviation.military 11 August 2002 |

Any engine temperature station using more than one probe is a Total. That is how it works. |

Nope. 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. One has to wonder if the trolls of ram will ever catch a clue. The irony of it all. |
