Abstract:
This invention serves to cool the lubricant used by a mechanical constant speed drive (CSD) driving an aircraft alternator which aircraft is powered by a turbofan engine. The system cooling capacity is supplemented by an existing engine fuel/oil heat exchanger thereby effectuating a reduction in size of the CSD fan air/oil heat exchanger and minimizing an aircraft engine performance penalty.
