The fuzzy mathematics method is introduced into the fault diagnosis of turbojet engine lubricating oil. The method of determining the fuzzy membership degree by historical data and expert ordinal number is proposed, and the fuzzy diagnosis model is established to solve the problem that one or several fault symptoms Accurately and quickly find the real cause of the failure, thus providing a scientific and feasible new method for the aircraft fault diagnosis and repair work.
