Abstract

The article addresses the problem of achieving component commonality in electrical power and electric propulsion systems for advanced aircraft, including "More Electric Aircraft" and those with hybrid or fully electric powertrains. The study aims to develop a computational model for substantiating the optimal type series of electrical power system components based on an analysis of the potential for commonality among key elements. The feasibility of commonality is assessed across various classes of aircraft. The results indicate that the greatest potential lies in switching devices and power converters, while the commonality of electrical machines and battery packs is significantly limited by specific performance requirements. The proposed approach enables the identification of priority areas for developing platform solutions aimed at reducing costs and improving operational efficiency. 

Keywords:
