The paper analyzes the need to design, develop and create an experimental installation to study thermal processes in the aviation engine oils at their forced convection and in various thermodynamic conditions close to the real ones in different aircraft engines. It presents the experimental installation design scheme to study heat transfer and sedimentation in the aviation engine oils at their forced convection without and with the electrostatic fields influence. Working sections schemes with one and three pairs of coaxial working needles are shown. Technique for conducting comprehensive experiments was developed. For the first time, influence of the transverse electrostatic fields on the heat transfer and sedimentation in the engine oils during their forced convection was studied. The proposed installation allows experiments not only with the aviation engine oils, but also with the liquid hydrocarbon fuels and their mixtures. Study results would contribute to creating new domestic equipment for various purposes and ensuring the improved characteristics in terms of lifetime, reliability and efficiency.

The article shows that various problems appear in the aircraft lubrication systems. These problems are associated with the quality of aviation motor oils, difficult thermodynamic conditions in their operation, negative sedimentation process, design features and deficiencies of piston aviation internal combustion engines, air-breathing engines, various aviation and ground power plants, as well in their filtering and cooling systems. Design and creation of new equipment foresees using aviation motor oils of various brands and properties; therefor, scientists, designers, engineers and constructors always need to know not only the selected oil general properties, but also its thermophysical properties, including density, thermal conductivity, viscosity and thermal capacity. The paper considers the issue of the MS-20 aviation engine oil density at various temperatures and pressures. A number of authors (and information sources) provide comparative data on this oil; its density values at different temperatures and normal pressure are having differences. Methods for obtaining density values of the aviation motor oils, including the MS-20 brand oils, are presented in experimental studies; in using nomograms, graphs and tables; in calculations using various techniques. The method for calculating the MS-20 oil density with an increase in temperature and pressure set out in the State Standards is demonstrated. A new abbreviated and effective method for calculating the aviation motor oils density with alterations in temperature and pressure, including the MS-20 brand oil, was developed and is presented. Recommendations are provided on the correct account of temperature and pressure when using density of the MS-20 and other types of the aviation engine oil to create new domestic ground, air, hypersonic and aerospace equipment for single-use and reusable for various purposes with improved performance in terms of resource, reliability and efficiency.
