Environmental control system including shared air source with balanced airflow output

An aircraft environmental control system (ECS) comprising:

• a bleed manifold to collect first bleed air flow supplied by a first aircraft engine, and to collect second bleed air flow supplied by a second aircraft engine;
• at least one air cycle machine configured to perform air conditioning on the first bleed air flow delivered from the first and second air flow delivered from the second delivered from the bleed manifold;
• and
• at least one electronic hardware controller configured to balance the first bleed air flow and the second bleed air flow output from the first engine and second engine, respectively, based on a bleed manifold pressure of the bleed manifold.

A method of balancing bleed air flow generated by a plurality of engines installed on an aircraft, the method comprising:

• generating first bleed air flow via a first engine, and generating second bleed air flow via a second engine;
• collecting, via a bleed manifold, the first bleed air flow and the second bleed air flow;
• performing, via at least one air cycle machine, air conditioning consuming bleed air flow from the bleed manifold;
• determining a bleed manifold pressure of the bleed manifold;
• and
• balancing the first bleed air flow and the second bleed air flow output from the first engine and second engine, respectively, based on the bleed manifold pressure of the bleed manifold.
