Abstract: The performance of oil-supplied regulation system greatly affects engine reliability. On the basis of analyzing various faults appeared for some missile turbojet, a fault mode set of engine oil-supplied regulation system was proposed. With a joint simulation flat of turbojet and its oil-supplied regulation system, three typical faults were simulated and evaluated with different model parameters and structure. The results indicate that oil-supplied regulation system faults have strong effect on turbojet’s operation. The adopted method is practical in the actual engineering.
