| Abstract: | Given the complicated traditional abrasion computing process, the opposite direction to model the abrasion loss of the metering valve was studied. Three ways to compute the abrasion loss were found. The result of some model of the aero-engine fuel control unit's metering valve test data shows that, the model of the differential equation of first order based on the time series can accurately calculate the abrasion loss of the metering valve, with the relative error less than 5%. This had the practical meanings to the life prediction of abrasion in the fuel control unit metering valve, providing a basis for the useful life of the fuel control unit. |
