An onboard rebreathing loop system resident on an aircraft for providing oxygen to aircraft personnel includes a ceramic oxygen generating system (COGS) module configured to receive an inlet air and output a high purity oxygen (O) gas into a breathing loop and a carbon dioxide (CO) scrubber module configured to receive exhaled air from the aircraft personnel and output a CO-scrubbed air into the breathing loop. The high purity Ogas and CO-scrubbed air are mixed to form a mixed gas having a partial pressure of Osuitable for breathing by the aircraft personnel. The onboard rebreathing loop system may further include an odor removal module, an air temperature and/or humidity control module to condition the mixed gas before breathing by the aircraft personnel, and a gas sensor module to confirm the partial pressure of Owithin the mixed gas before breathing by the aircraft personnel.

Closed or semi-closed loop onboard ceramic oxygen generation system

An apparatus for adjusting the partial pressure of gaseous mixtures comprises a housing and piston. The housing defines a chamber coupled to an oxygen metering orifice, diluent metering orifice, vent port and gas outlet. The oxygen metering orifice provides oxygen to the chamber and the diluent metering orifice provides diluent gas to the chamber. The piston is movably positioned in the chamber and includes first and second sealing devices. The chamber is sectioned into a mixing chamber, a diluent chamber and a reference chamber located between the mixing chamber and diluent chamber. The diluent chamber receives a diluent gas referenced at ambient pressure and the reference chamber is charged with a gas having a reference pressure. The piston changes positions within the chamber depending on a force balance created by a pressure differential between the reference pressure and ambient pressure.
