EX-17 Underwater Breathing Apparatus.

Abstract

The EX-17 Underwater Breathing Apparatus (UBA) was assembled and tested by the Navy Experimental Diving Unit (NEDU) to determine the suitability of a closed-circuit apparatus for deep diving applications and as a tool for in-house physiological function studies. The EX-17 is a modified version of the Swimmer Life Support System (SLSS) MK 1, a closed-circuit, mixed-gas, self-contained UBA. The EX-17 configuration includes a dry helmet and umbilical gas supply. The EX-17 is intended to operate at depths to 2,000 feet of seawater (fsw) in the usual closed circuit mode, and in an emergency open circuit mode. Preliminary tests were successful despite minor technical problems. During Deep Dive 77, the EX-17 demonstrated capability to support a diver doing light, moderate, and heavy work at depths from 1,054 to 732 fsw. NEDU is performing further investigations to insure EX-17 UBA life support capability and mission reliability at depths to 2,000 fsw. (Author)
