Aircraft occupant chemical oxygen system with short and long duration

A chemical oxygen core for a chemical oxygen generator includes at least one layer of an oxygen-generating composition. In some examples, the at least one layer comprises includes a metal powder fuel, a transition metal oxide catalyst, and an oxygen source. In various examples, the at least one laye...

Zusammenfassung:A chemical oxygen core for a chemical oxygen generator includes at least one layer of an oxygen-generating composition. In some examples, the at least one layer comprises includes a metal powder fuel, a transition metal oxide catalyst, and an oxygen source. In various examples, the at least one layer includes less than approximately 0.1 percent by weight of the transition metal oxide catalyst. In certain examples, a chemical oxygen generator includes a chemical oxygen core and a perforated metal covering surrounding the chemical oxygen core along a length of the chemical oxygen core. In some aspects, the perforated metal covering has an opening ratio of approximately 0 to 100 percent.
