Analisis of methods for calculating oil pumping through the supports of a projected low- power gas turbine installation.

Abstract

The article presents an analysis of methods for calculating oil pumping through the supports of low-power gas turbine installations of errors in their application. This analysis includes consideration of the methods of CIAM, PJSC UEC – Kuznetsov, GP Ivchenko – Progress, the methodology of V.M. Demidovich and I.A. Birger, which is based on numerous experiments and empirical dependencies, which significantly complicates the calculation and narrows the scope of their specific application. It is very important that when calculating the heat release in the rotor support nodes and determining the oil pumping needs, errors in determining these parameters occur. To assess the effect of errors on the calculated parameters, the article presents the calculation of the maximum errors in determining the oil pumping. doi 10.54708/19926502_2024_2841063
