UAVs Electromagnetic Resistance Study under the Powerful Electromagnetic Pulse Influence

In this paper we study the on-board equipment noise immunity of an unmanned aerial vehicle under a powerful-pulsed electromagnetic effect. We propose an approach for predicting the unmanned aerial vehicles electromagnetic resistance based on the on-board equipment noise immunity study. The electromagnetic environment in places where on-board equipment is installed and electromagnetic interference in communication lines under a powerful-pulsed electromagnetic effect are analyzed. The work examines the powerful-pulsed electromagnetic effect on an unmanned aerial vehicle, the structure of which is made of composite material. We considered a practical example by predicting electromagnetic situation into the unmanned aerial vehicle fuselage and electromagnetic interference in antenna-feeder paths under powerful-pulsed electromagnetic effect. The electromagnetic interference levels calculated on the load of the antenna-feeder path and the electromagnetic field strength in the unmanned aerial vehicle intra-fuselage space reach quite high values and can lead to on-board equipment malfunction under powerful-pulsed electromagnetic influence. Basic approaches are proposed to ensure the unmanned aerial vehicle electromagnetic stability under a powerful-pulsed electromagnetic effect.
