The effectiveness of on-board aircraft power sources in line with the trend of a more electric aircraft

The subject of the paper is analysis, mathematical model and computer simulations of on-board power sources in the form of a generator or integrated starter/generator unit in terms of their work efficiency, implemented on aircrafts, compatible with the concept of a more electric aircraft. It should be noted that the dynamically developing trend of the electrified aircraft includes both the military aircrafts of the aviation company (Lockheed Martin) in the field of its leading products JSF (Joint Strike Fighter) F-35 and F-22 Raptor) as well as the leading civil aviation corporations (Airbus, Boeing) in in the context of modern passenger Airbus aircrafts (A-380, A-350 XWB) and Boeing (B-787 Dreamliner), compatible with the MEA/AEA concept. The main goal of the paper is to create a mathematical model, conduct its analysis and selected simulations of the on-board source (generator) in the scope of its correct operation in the context of the functions performed (generation, processing, distribution) of high-quality electricity on board of a modern aircraft. In the final part of the paper, based on the analysis of the subject of the research, a mathematical description and selected simulations of the created model, practical conclusions were formulated, reflecting the functionality and efficiency of operation of electric power sources of the modern aircraft.
