This paper presents the results of a study aimed at improving the air-cooling system on aircraft engines and validating the relevant methodologies. It includes experimental studies and develops a methodology of heat engineering research using a full-size aircraft piston engine in test-bench conditions with detailed thermometering of cylinder and piston assembly parts. A part of the work focuses on heat transfer from gas to combustion chamber walls and within the cooling system.
