Abstract
A thermal management system for an aircraft engine. The thermal management system extracts interstage engine bleed air from the engine's compressor and performs three stage cooling of the interstage engine bleed air using two heat exchangers and a vapor cycle system evaporator. The cooled air is then further cooled by expansion through a set of turbines and subsequently used as a heat sink for heat loads on the aircraft.
