Aerospace Instrument-Making Annotation << Back MATHEMATICAL MODEL OF GENERATION SYSTEM ELECTRIC ENERGY OF AIRCRAFT ON BASED ON GENERATOR WITH PERMANENT MAGNETS V.E. Vavilov, F.R. Ismagilov The article presents a generalized structural model of the power generation system (EGS) of an aircraft (LA) based on an electric generator (EG) with permanent magnets (PM), which allows for research, including EGS, integrated into the power plant. On the basis of studies of the developed structural model and the obtained criteria for the efficiency of the SGE PA, it has been proved that for the SGE with a power of 250 kW, the use of 115/200 V, 400 Hz is impractical due to the large mass of wires (more than 2 times compared to other competing options). Keywords: aircraft; power supply system, power generation channel. DOI: 10.25791/aviakosmos.05.2019.638 Contacts: E-mail: S2_88@mail.ru Pp. 34-45.
