Abstract:

The static performance characteristics of USAF oxygen regulators were evaluated utilizing the regulator test stand at USAFSAM. Outlet suction pressures, flows, positive pressures, and delivered oxygen dilutions were observed and plotted as functions of operational altitudes. General findings indicated that 1 excessive oxygen addition occurs in all models, especially at low cabin altitudes 2 positive pressure schedules generally conform to specifications 3 negative suction pressures for most regulators are less than -1.0 in. H2O. The validity of static evaluation is discussed and data interpretation is considered with respect to biomedical compatibility that emphasizes maintenance of crewmember physiological sufficiency.
