Abstract :
The performance of the IDG Oil Cooler affects the initial detection of the
IDG lubrication failure. The greater the efficiency value of IDG Oil Cooler
indicates the condition of lubrication is in good condition but if the value of the
effectiveness perfomence of IDG Oil Cooler falls below 80% indicates the
lubrications system failure (The default value of the pump flowing by 4 GPM
(0,252 kg/s) with an efficiency of 81,3%, but what happens is the pump only flows
under 4 GPM which equal to 1 GPM (0,063 kg/s) with an efficiency of 63,58% so
that efficiency of IDG Oil Cooler decreases). The reduced value of the APK
efficiency is on of the parameter that the lubrication system has ttrouble.
