In technical life, especially in the case of propulsion units used in the vehicle industry, the energetic behavior of propulsion units is of great importance, which typically means the discovery of propulsion unit loss sources and the determination of their magnitude (Concli, 2016).	cache/cet-14353.pdf	txt/cet-14353.txt
