Adaptation of the self-contained aircraft oxygen system (SCAOS) for Navy use formed a part of the overall development program. The main difference between Navy and Air Force practice as it affects the system is the use of a chest-mounted miniature breathing regulator by the Navy, while the baseline Air Force system employs panel-mounted regulators occupying the envelope of the CRU-68/A regulator. A primary design consideration for Navy use is the capability of the system to operate in a submerged and flooded cockpit to a depth of 33 feet. The chest-mounted regulator allows the aviator to be in any orientation without materially affecting the mask pressure when underwater. The baseline SCAOS design uses an 1800 psi emergency oxygen supply (in addition to the bailout supply) to provide oxygen for 30 minutes at 30,000 feet in the event of a total system failure. This volume describes the design, development and testing of a T-39 configurated SCAOS system as modified for Navy use and the design of an emergency supply for 10 minutes operation underwater to a depth of 33 feet.
