NASA FAULT TREE HANDBOOK WITH AEROSPACE APPLICATIONS (VER. 1.1) (AUG 2002)

NASA FAULT TREE HANDBOOK WITH AEROSPACE APPLICATIONS (VER. 1.1.) (AUG 2002).,This handbook is an update of the original Fault Tree Handbook published in 1981. It is written for the informed reader who has some knowledge of system analysis and has knowledge of basic mathematics. This handbook is intended for system analysts, system engineers, and managers. No previous knowledge or training in statistics, reliability, or risk analysis is assumed. Basic concepts of statistical analysis, reliability analysis, and risk analysis are presented in relevant chapters and in the appendices. The first part of the handbook describes the concepts, steps, tools, and uses of fault tree analysis (FTA). FTA is a deductive, failure-based approach. As a deductive approach, FTA starts with an undesired event, such as failure of a main engine, and then determines (deduces) its causes using a systematic, backward-stepping process. The second part of the handbook contains examples of the application of FTA in studies that have been previously performed. The focus is on aerospace applications. The examples include the rupture of a pressure tank (a classic FTA example), failure to initiate and terminate thrust in a monopropellant propulsion system, failure of a redundant container seal (design analysis), and a dynamic FT analysis of a mission avionics system..
