The safe-set logic compares the NSD turbine speed sensor to the Generator Keyphaser speed sensor in the Bently vibration system. A difference greater than 150 RPM for 10 seconds triggers a No Motored shutdown independent of T48 temperature in this case, because potentially something is failed...

The PGT25+ is the GE Aviation LM2500 aero derivative engine packaged back in the day by Nuovo Pignone. PGT is sort of their brand name for their package. The LM2500 is a two shaft machine with the LP turbine being a free power turbine. Nuovo Pignone was primarily a driven process...

On aero engines the system response and fuel metering accuracy is critical. Aero engines have fast transient performance requirements. For example to protect against flameout and guard the compressor stall line. For DLE aero engines the game is amped up. There are specialized pressure...

I am not an expert in vibration, but I had to do a little bit once upon a time evaluating and testing different systems. I have a calculator program I used from this web site that I have squirreled away. http://www.ctconline.com I do not see the download any more, but they have an on line...

One more thought is to check the PS3 instrumentation sense line for loose fittings or water in the line ... possibly if accidentally not isolated during a water wash.

* On this system you would have dual redundant controller cards that current share. * When one LVDT, one card, or one side torque motor fails the other card takes over. * The Woodward servo (HSU) on the gearbox has 3 torque motor coils for each VG loop. * For simplex cards two coils are...
