Numerical Simulation of the Lubrication System of Aircraft Piston Engines

The paper presents the results that served as a methodological basis for creating a digital twin of a piston engine lubrication system. A CAD model of the oil pump and the oil line of the engine lubrication system were built. A method of reverse engineering of the pump performance characteristics is proposed and its operating characteristics are constructed. The models of the gerotor oil pump and the main line were verified based on experimental data, which made it possible to create feedback for the digital twin. Based on the calculations carried out, recommendations were developed to improve the accuracy of constructing digital twins of a gerotor oil pump and an oil line.
