A gas generating system comprises an air separation module (ASM) in fluid communication with a nitrogen enriched air (NEA) line and an oxygen enriched air (OEA) line. A valve is positioned in the OEA line and an oxygen sensor is positioned in the NEA line. The valve can be modulated in response to the oxygen sensor to create a backpressure forcing more airflow into the NEA line. The OEA line can be backpressured until a predetermined NEA oxygen concentration is reached.

Enhanced OBIGGS

Apparatus, systems, and methods for the efficient decomposition of ozone in an air stream from an air intake of an aircraft. The apparatus includes a titania catalyst support on a substrate, and a catalyst composition on the titania. The catalyst composition comprises a silver-based component, comprising silver metal or silver oxide, and a palladium-based component comprising an oxide of palladium or palladium metal. The air stream may be from a dedicated ambient air compressor or from bleed air from a gas turbine engine. The invention allows for the effective removal of ozone from the air stream to provide cleansed air having an ozone level of 0.1 ppm or less over a range of operating temperatures from 100 to 500&#xb0; F. and above during a service period of at least 20,000 hours or a time period of not less than 5 years.

Ozone removal system and method for low and high temperature operation

An environmental control system includes a catalytic reactor and a post treatment filter for cleaning incoming air, and a vapor cycle system for conditioning the air.

Environmental control system including vapor cycle system and isothermal CATOX/PTF

A filter includes a catalyst for oxidizing NOx to NOand an alkaline for adsorbing the NO.

NOx filter

An air cleaning system and method employs both particulate and gaseous contaminant removal from a flowing air stream to improve air quality in a selected environmental space. Particulate contaminants are removed by an appropriate filter. Gaseous contaminants such as VOCs, CO, and O are removed using a catalyst to oxidize such contaminants. The air stream is selectively heated to provide an adequate catalyst reaction temperature and the heat energy is then recovered by a heat exchanger. Various sensors are employed to monitor flow rate, air composition, temperature and pressure. A controller is programmable to control air quality for either minimizing contaminants or minimizing energy usage required to achieve a selected minimum air quality over a period of time.

Smart air cleaning system and method thereof

In an aircraft, tap water is filtered, vaporized and injected into a trim line of an environmental control system. Filtering is performed by a reverse osmosis filter. Hot, humidified air leaving the trim line is supplied to a cabin of the aircraft.
