Abstract

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 (O2) gas into a breathing loop and a carbon dioxide (CO2) scrubber module configured to receive exhaled air from the aircraft personnel and output a CO2-scrubbed air into the breathing loop. The high purity O2 gas and CO2-scrubbed air are mixed to form a mixed gas having a partial pressure of O2 suitable 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 O2 within the mixed gas before breathing by the aircraft personnel.
