The method of civil aircraft engine condition monitoring and fault diagnosis is studied. Come up with a new monitoring techniques, which can reflect real parts fault information, early warning failure. In this paper, e-lectrostatic monitoring principle is analyzed, and electrostatic monitoring system and experimental platform had been designed and developed. The circulation lubrication conditions pin plate sliding friction and wear experiment is car-ried out, using a homemade electrostatic sensor circuit in fluid abrasive grains to montor. The results show that the oil-line electrostatic sensor can monitor the charged particles of various metallic materials, inductive voltage is rele-vant to the debris size, shape of the inductive voltage is relevant to the debris charging characteristics, indicating a-vailability of on-line monitoring in the model of electrostatic sensor and providing a further evidence for the fault.
