ABSTRACT:
An air generation unit includes first and second air cycle machines (ACMs), each having first and second turbines. A manifold is arranged between the first and second ACMs and is in fluid communciation with each of the first and second turbines of the first and second ACMs. A condenser is arranged between the ACMs and is in fluid communication with the manifold. First and second valves are disposed within the manifold and control flow of air between the turbines and the condenser. An actuator is assembly is connected to the valves for moving the valves between a plurality of positions. The valves selectively close off or prevent the flow of air from the turbines of one of the ACMs in the event that the ACM is not needed or malfunctions.
