Configurations for Grounding Plane and Current Return use in Non-metallic Aircraft Proceedings Article Sousa, Marina Guimarães; Nunes, Sidney Osses; Filho, Jayr Amorim; Adabo, Geraldo José Resumo | Links | BibTeX | Tags: composite material, Current return, effects of lightning @inproceedings{Marina2009Currentb, This paper evaluates metallic grid solutions for aircraft with a composite fuselage to conduct the power return current, and to work as a voltage reference plane. Also, there is concern about the aircraft protection against lightning strikes, as composite tends to be more susceptible to direct effects damage than metal structures. Configurations of metallic current return structures are presented, and the analysis on them stands on the response of the structures to the injection of a standard lightning current, based on electromagnetic effects simulation software. The lightning strike current distribution pattern over the return structure is important for protection of inside installed equipment, and each proposed metallic grids for current return presents different response lightning discharges. Key words Current return, effects of lightning, composite material. |
