Abstract

The fuel supply system on the example of the short-resource turbojet engine is considered aiming to determine the impact on the automation system of aircrafts. For this purpose, the fuel supply circuit of an engine is presented and its basic elements are displayed. Features of the functioning of the fuel metering unit during the aircraft flight process are described, as well as the properties of aviation fuels, such as viscosity, density, thermal stability, saturation by air, compressibility, and fuel purity. Based on the analysis of the fuel characteristics and properties it is ascertained that such process as hydrodynamic cavitation, as well as positive feedback, exert key influence on the automation functioning.
