Evaluation of Scott Aviation Corporation Demand Type Closed-Circuit Oxygen Scuba.

摘要

The Scott Aviation corp. double-Demand Oxygen SCUBA developed under specification requirements of BUSHIPS Contract NObs 88356was evaluated through a series of laboratory tests of individual components and subjective tests of the complete assembly. The contract called for inclusion of mechanical features not previously included in the U.S. Navy equipment. These features were (1) a hydrostatically balanced demand system, (2) 3000psi oxygen cylinder with a half bottle pressure reserve, (3) breathing bags of dipped neoprene latex construction, (4) gas control to consist of demand valve,needle control set for 0.9of a liter and a bypass, (5) the swimmer should be able to cut the demand system out of the circuit when necessary.
