Fault Tree Analysis is a logical and structural method that can help identify potential causes of system failure before the failures actually occur. It makes use of the fault tree diagram which includes most fault information to analyze fault forming basipetally. In order to analyze the faults of shielded pump which is used in the rocket power system, we analyze them based on Fault Tree Analysis in this paper. The Fault Tree of shielded pump is established and the events that most likely to cause the system...
