Claim:
1. A system for providing regulated flow of oxygen comprising: a first on-board oxygen supplier configured to supply oxygen in an initial stage, said first on-board oxygen supplier including a combination of a pressurized oxygen cylinder and a chemical oxygen generator, wherein said chemical oxygen generator comprises a plurality of igniters; a second on-board oxygen supplier configured to supply oxygen in a subsequent stage, said second on-board oxygen supplier includes a solid electrolyte oxygen separator configured to catalytically separate oxygen from a supply stream of air; a pulsed oxygen delivery subsystem connected to the first on-board oxygen supplier and connected to the second on-board oxygen supplier; and a controller configured to control the first on-board oxygen supplier and the second on-board oxygen supplier, the controller directing oxygen from the first on-board oxygen supplier during the initial stage to the pulsed oxygen delivery subsystem, and then phasing out supply of oxygen from the first on-board oxygen supplier in the subsequent stage while directing the second on-board oxygen supplier to supply oxygen to the pulsed oxygen delivery subsystem.
