Abstract

Given the large number of new technologies developed (fuel cells, more advanced engines,electrified systems), the idea appears, increasingly fortified, of the use of greater electrical powerin aircraft. This is how the concept of MEA ("More Electric Aircraft") first emerged. MEAaims to replace mechanical, pneumatic and hydraulic systems with electro-electronic equipment.These systems introduce major improvements, such as lower maintenance costs, greater reliability,fault detection, and weight and volume savings. The concept of All Electric Aircraft (AEA)considers that the propulsion will also be electric. It is possible that the propulsion of theaircraft is exclusively electric or that it is hybrid, with other thermal engines technologies. Aircraftpropulsion requires high performance, power density, efficiency, reliability and availability. Concernabout aircraft electromagnetic compatibility (EMC) studies is increasing due to the extensive use ofelectronic and wireless technologies that can lead to electromagnetic interference (EMI). NumerousEMI problems have been reported in the aerospace industry.The study on electromagnetic compatibility between the systems that will compose the aircraftis a relevant aspect to be explored, especially when observing the power required for propulsion. Through numerical methods, studies will be carried out in order to identify the possibleCrosstalk effects that may arise between cables and connections inside the aircraft. Usingsoftware for EMC simulations, electrical conduction conditions will be evaluated in models of realproportions and, thus, analyze their critical points and possible failures.
