Abstract
Currently, special attention is paid to the aircraft fuel quality as a component of safety to ensure trouble-free operation of the fuel system. The existing system of quality control involves periodic sampling of the fuel in the container and their subsequent control by the normalized quality indicators that do not identify possible reasons for the deterioration of these indicators to remove them for trouble-free operation and do not identify the factors of pollution sources. The monitoring system generally ensures the implementation of measures to preserve the quality of aviation fuel and flight safety of serviced civil aviation airlines at current level according to regulatory requirements. The article describes the mathematical model for calculation parameters of indicator filtering partitions based on cascade filtration theoretical studies of mechanical impurities. Pores of indicator filtering partitions calculated by means of mathematical model have been experimentally tested on simulator stand and showed a good convergence of calculated and experimental results. The use of cascade filtration of fuel with different indicator partitions parameters made it possible to develop a device for fuel purity monitoring, allowing continuous (inline) monitoring the level of liquid flow contamination at various points of technological equipment (for example, after the pump, at the inlet and outlet of tanks and units, the output of the filter, etc.) and to carry out functional diagnostics of units condition process equipment by monitoring changes of particle parameters and the wear occurrence.
