U.S. Navy Unmanned Test Methods and Performance Goals for Underwater BreathingApparatus

摘要

The Navy Experimental Diving Unit (NEDU) is the United States Navy's facility forthe test and evaluation of underwater breathing apparatus (UBA). Every military and commercial UBA considered for use by the U.S. Navy is sent to NEDU for an in-depth evaluation. The evaluation encompasses UBA performance, material suitability, human factors and system reliability. This technical manual is an update of NEDU Report1 3-81. It presents the updated unmanned performance goals and test methods currently used by NEDU to evaluate UBA. Chapters 1, 2, and 3 give a general discussion on UBA characteristics and evaluations while Chapter 4 discusses specific instrumentation setup and detailed test methods for specified types of UBA. Chapter 5 describes the analytical software, Chapter 6 details the testing of electronic UBA, and Chapter 7 answers questions about statistical analysis of testing results. Chapter 8 is a mathematical discussion of the work of breathing, resistive effort, and RMS pressure calculations. This section is available from NEDU as a computer file called WOBNEW.mcd; an interactive document for use with MathCad for Windows, version 4.0 or 5.0 running on a DOS style microcomputer.
