Unmanned Evaluation of the U.S. Navy MK 15 Closed-Circuit UBA (underwater Breathing Apparatus).

Le résumé fourni par la source

The purpose of the unmanned testing on the U.S. Navy MK-15 closed- circuit (C/C) underwater breathing apparatus (UBA) using a hyperbaric breathing simulator was twofold: (1) to evaluate breathing resistance/breathing work characteristics of the MK-15 UBA using a variety of mouthpiece/hose and full- face mask (FFM) configurations; and (2) to evaluate carbon dioxide (CO2) absorbent canister duration at a depth of 50 feet-of-seawater (FSW) in a wide range of water temperatures. Breathing resistance/breathing work studies were made using five different mouthpiece/hose and FFM configurations at depths to 150 FSW at simulated work rates ranging from light to extreme. CO2 canister duration tests were conducted in water temperatures ranging from 29 to 90 F.
