Abstract
Fuzzy fault tree analysis of uncontained event for aero-engine rotor is performed. The theory of fuzzy fault tree analysis was introduced firstly. Then the fault tree of uncontained event for aero-engine rotor is established, in which the descending method is used to find minimal cut sets. Further more, the interval representation and calculation strategy is presented when the symmetrical L-R type fuzzy number was chosen to describe the failure probability, and the built fault tree is analyzed quantitatively.
