What is this scoop found on the core of a PW1127G engine near the CC/turbine section? The view is back to front, the scoop is at 10 o'clock on engine 1. What would be it's function? I need supportive literature as well if possible.
That scoop allows air to go through the Engine Air/Oil Exchanger which cools the engine oil with fan bypass air.
Engine oil that is cooled by the air/oil heat exchanger decreases the quantity of heat that must be moved from the oil to the fuel in the fuel/oil heat exchanger.
