Development Trends and Prospects of Electromechanical Energy Converters and Power Electronics Units for Aircraft with Electric and Hybrid Propulsion

This article considers the conceptual state of traditional aircraft technology. It is shown that achieving technological leadership requires the development of aircraft based on electric and hybrid propulsion systems. It also examines the current state of electric machine development, drawing the conclusion that a specific power of 16.1 kW/kg for electric motors will not be achieved until 2030. It is also shown that the development of hybrid and electric propulsion aircraft requires mastering serial production of such aircraft, obtaining Rosaviatsia or EASA certification, and accumulating sufficient flight hours on aircrafts with such electric motors.
