Description
Summary:The paper discusses the derivation of criteria for pollutant mineral matter in fuel that is hazardous for fuel metering equipment (FME) of aircraft jet engines. It is concerned with mechanical impurities captured during fuel transportation, pumping, draining and storage, and with quartz of various range of dimensions. With optical microscopy and the requirements for model matter to obtain a mathematical description of the aviation fuel sedimentation process based on a particular solution of the Navier-Stokes equation, a sphericity coefficient of 0.835 was adopted for a ball. Based on the data obtained, 4 criteria for matter hazardous for FME were identified: hardness, size, density, shape.
