A MODEL OF COMPRESSOR BLADES CONTAMINATION IN AVIATION GTE IN OPERATION

Abstract

An important scientific problem, namely the development of a mathematical model of airborne gas turbine engine blades contamination in operation is solved in the paper. The mechanism of adhesion of dust particles to the blades of GTE is revealed, depending on their size and speed. The structural analysis of dust samples taken at different airfields, as well as deposits on the blades of motor compressors, has been carried out. As the angle of inclination of the surface decreases with respect to the axis of the flow, the marginal size of the area saturated with adhered particles decreases. As a result of consideration of the processes of mass transfer, adhesion and separation, it was concluded that the process of bladder contamination depends on many factors, and the maximum thickness of the layer of deposits is almost equal to the thickness of the boundary layer.
