Abstract: An ozone converter that includes an outer housing having an inlet and an outlet is disclosed. In this embodiment the ozone converter includes a core disposed within the outer housing and a bypass cylinder disposed between the inlet and the outlet and that passes through the core such that air within the bypass cylinder does not contact the core. The ozone converter of this embodiment also includes a blocking sleeve that surrounds a portion of the bypass cylinder and that is moveable from a first position to a second position. When the bypass sleeve is in the first position air that enters in the inlet is directed by the blocking sleeve into the bypass cylinder and when it is in the second position air that enters the inlet is allowed to enter an outer passage between the bypass cylinder and the outer housing.

Abstract: A water collector is telescoped into the interior of an aircraft condenser. The condenser has a header for collecting air from the condenser and the water collector is disposed at least partially within the header.

Abstract: The present invention provides an air generation unit (AGU) including a pressurized air source, such as an engine providing pressurized air. First and second air cycle machine (ACM) are fluidly connected to the pressurized air source for receiving the air. A heat exchanger interconnects the first and second ACMs. The heat exchanger mechanically supports the first and second ACMs by flexible isolators, which accommodates the thermo expansion of the heat exchanger through out the operation of the AGU. The heat exchanger includes a primary heat exchanger that cools the air from the air source. The ACMs each include a compressor receiving the air from the primary heat exchanger to provide compressed air. The compressed air is sent to a secondary heat exchanger to be cooled. The compressed air is passed through a condenser and a water collector to remove moisture from the air for being sent to a first turbine.

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.
