SELF-COOLING LOOP WITH ELECTRIC RAM FAN FOR MOTOR DRIVEN COMPRESSOR

摘要

A motor driven compressor system includes a motor with an internal cooling loop. The internal cooling loop draws cooling air from outside the motor driven compressor system. At least one compressor is driven by the motor. A heat exchanger is in fluid communication with the at least one compressor and the cooling loop and is arranged in a ram air duct. An on board inert gas generating system (OBIGGS) for a gas turbine engine and a method of cooling the system utilizing such a compressor system are also disclosed.
