Simulation of contactor for regional hybrid-electric aircraft
Keywords:
hybrid airplane, KHVDC, contactor, simulationAbstract
To meet the decarbonization objectives set forth by the European Union, the aerospace sector is engaged in the development of a novel category of regional hybrid aircraft that integrates advanced DC technologies alongside conventional systems. This publication presents the proposed direct current (DC) system of the next-generation hybrid aircraft focusing on one of the protection elements developed for the kilo-volt DC (KHVDC) network, namely a mechanical contactor. The contactor design, its key characteristics as well as the chosen numerical model are presented and discussed in detail. The magnetohydrodynamics (MHD) model, details and focuses on a solution that integrates two distinct Ansys software packages, Fluent and Electronics Desktop (Maxwell 3D), chosen to enhance the electric arc modeling in non-linear magnetic environments. The qualitative results obtained from the numerical model will be discussed against experimental observations.
