Suk, MichalČerňan, Jozef2021-06-182021-06-182021http://drepo.uniza.sk/handle/hdluniza/422I will briefly address the three orientations of my paper in this scientific article. I will not go into details in the article. In the first part I will briefly describe the design procedure of a piston engine lubrication system, the requirements that a lubrication system should meet with respect to different types of piston engines and their focus, elements of the lubrication system and the properties of oils as lubricating fluids.In the next part I will describe the types and constructions of aircraft engine beds, technical requirements for aircraft engine beds and individual loads that the aircraft engine bed must withstand. In the last part I will focus on aircraft propellers. I will explain the basic principle of the propeller, the individual rules for selecting a propeller for a piston engine, safety requirements for an aircraft propeller and the dividing of basic types of aircraft propellers for aircraft piston engines.skhttp://creativecommons.org/licenses/by/4.0/Lubrication systemwet sumpdry sumplubrication fluidsengine bedaircraft envelopepropellerblade air foilConference paperhttps://doi.org/10.26552/pas.Z.2021.1.27
