Resources in this topic area are primarily articles that include FTA case studies and software tools for FTA. FTA is an intuitive, graphical approach for reliability analysis of these designs. Deployable mechanisms are common in smallsats, and are often custom built for a particular payload. The logic and events captured in the fault tree can be used to predict the fault probability and identify efficient approaches (e.g., modified designs or operational plans) to reduce the overall probability of a fault. As opposed to a failure mode and effects analysis (FMEA), an FTA is a top-down approach which starts with the higher level system fault and expands downward to identify events or combinations of events that would result in the fault. Fault tree analyses provide a graphical, logical representation of the reliability of a system against individual faults. This topic area covers fault tree analysis (FTA) of spacecraft mechanisms.
