Patent number: 9580177Abstract: Provided herein is a hybrid system for generating oxygen on-board an aircraft for passengers and/or flight crew to breath. The system includes a first chemical oxygen generator component configured to promptly supply oxygen suitable for breathing upon an emergency situation arising and during an initial descent mode. Heat produced from the exothermic decomposition reactions inherent in several types of chemical oxygen generators can be harvested and feed to a second oxygen generator. The second oxygen generator is a solid electrolyte oxygen separation system that catalytically separates oxygen from air inside specialized ceramic materials at high temperatures, about 650° C. to 750° C., using electrical voltage. The ability to feed heat from the first oxygen generator to the second oxygen generator substantially reduces the lag time until the second ceramic oxygen generator is available to take over as the oxygen supply.Type: GrantFiled: August 12, 2015Date of Patent: February 28, 2017Assignee: B/E Aerospace, Inc.Inventors: Girish S.

Patent number: 9550575Abstract: The present invention provides a system and method for supplying and managing oxygen suited for use on-board an aircraft for providing breathable oxygen to pilots and cockpit crew. Components of the system work together to optimize oxygen utilization while reducing costs from maintenance and added weight of traditional pressurized gaseous cylinders. Components include a rapid oxygen supply for immediate use in emergency situations, an on-board oxygen generator (OBOG), a controller, a pulsed oxygen delivery subsystem that detects inhale/exhale phases and adapts to physiological requirements, and a breathing mask for each pilot and cockpit crew member.Type: GrantFiled: May 25, 2012Date of Patent: January 24, 2017Assignee: B/E Aerospace, Inc.Inventors: Girish S.

Patent number: 9550570Abstract: The present invention provides a system and method for supplying, generating, conserving, and managing oxygen that is ideally suited for use on-board an aircraft for supply of breathable oxygen to passengers and flight crew. The system includes several components that together optimize oxygen utilization while reducing costs from maintenance and added weight of traditional pressurized gaseous cylinders. Components of the system include a pressurized cylinder of oxygen enriched gas or a chemical oxygen generator for rapid use in emergency situations, an on-board oxygen generator (OBOG) of the ceramic oxygen generator (COG) type incorporating solid electrolyte oxygen separation (SEOS) technology, a controller, a pulsed oxygen supplier, a crew/passenger breathing mask, and one or more sensors including sensors that detect inhale/exhale phases and communicate with the controller so that flow of oxygen may be regulated for conservation and to adapt to physiological needs.Type: GrantFiled: May 25, 2012Date of Patent: January 24, 2017Assignee: B/E Aerospace, Inc.Inventors: Girish S.
