An aircraft environmental control system (ECS) provides fresh air for the cabin of an aircraft by using electric motor driven compressors in place of traditional engine bleed air. Conventional aircraft ECS use an engine bleed to provide the pressurized fresh air flow for an aircraft cabin. However, such a system suffers from the disadvantage of requiring additional fuel consumption in order to provide an adequate engine bleed source. The present invention, using a zero bleed, electric powered architecture, does not suffer from this drawback of the conventional ECS.
