Hello Everyone,
I'm running the Compressor performance check , and I have all values of compressor pressure above above a normal sittuation in T.O. 2J - T56-56 SWP 058 04, always in HIGH ZONE. In troubeshotting we have notice that PS3 (CDP) pressure begin taking in the 2 hours position, but in related manual Figure 2 the CDP pressure has to be taken in 11 hours position.
I am still waiting for the next engine come from shop to test cell to fix that.
My question is the oil tube (HOT OIL) that pass in the diffuser in 2 hours position next to the bleed presure tap (where I take the CDP pressure actually) can affect my CDP reading like that ?
27,58 inHg
CIT (TAMB) 74 F
PS3(CDP) EST. 103.3 psi
PS3(CDP) READ 112.03 psi
COMPRESSOR RATIO 8.02
ENGINE PERFORMANCE 97,18 %
Thaks for all!
