Hello !

I couldn't find this one:

during engines check, Torque in one engine shows aprox 4000 less than others,

TIT normal, RPM normal and Flujometer less than normal.

What is the failure?

I'm trying to pass this test, any help?

thx,

Juan

For low torque, accompanied by low fuel flow at normal TIT the probable cause can be:

1- Compressor erosion, dirty and/or FOD.

2- Compressor 5th and 10th stage bleed valve open above 94%.

3- Bleed air leaks.

(ref. “Malfunction Analysis†page 70). Booklet Issued by “R-R†1998 Hercules Operations, Safety Briefing and presentation.

“Aside of asking†the behaviour of the engine below x-over and above x-over with TD NULL.

I may add beside the above the following:

1- Malfunction of engine anti-icing air valve can be one of the causes, but not the only cause (due to the higher drop on the torque “4,000â€)

2- There are some cases caused by (harness malfunction) in which imposing higher than actual temperature signal to both (TD Amp. & Indicator) which also may leads to the same condition.(can be detected by TD null operation)

I think perhaps Juan means flukmeter, what we used to know as a PSM-6. Keep in mind he is posting in his second language.

I think he is referring to the Fuel Flow indicator (Torque, TIT, RPM & F/F). Some times communicating in a second language can be difficult for us to understand:-))

Do a flag test on your engine. to do this put a peice of rag on a stick and open the clam shell doors, trhen have your engine running at HSGI and have a person stick it next to the ports at the fire wall. if the flag moves you could have a puck stuck open above 94% RPM.

Somebody help me out, what exactly is a flujometer?

Seems no body reads our technical dictionary!!

Floodometer,flujometer,and flowmeter, each is a compound name of instrument used to measure fluid per unit of time.

When fluid passing through is more than suppose to be we call it floodometer.

When less than suppose to be we call it flujometer.

And when as suppose to be we call it flow-meter.

Ref. Captain’s Technical Dictionary.

I'm with Herk 308 on this one. I'm thinking Speed Sensitive Valve. 4,000 to 5,000 inlbs is the magic numbers for speed valve failure.
