WIPO Patent Application WO/2022/045539
Kind Code:
A1
Abstract:
The present invention relates to an aircraft wing. The aircraft wing comprises: a lightning protection apparatus which is installed on the surface of the aircraft wing to transmit the electrical energy of lightning to the surroundings when the aircraft wing is struck by lightning, and has an embossed pattern formed on a metal plate; and an electromagnetic wave absorption apparatus which is installed so as to contact the lightning protection apparatus and absorbs electromagnetic waves, and which includes an electromagnetic wave absorption layer formed of dielectric fibers. The pattern of the lightning protection apparatus may comprise: a first parallel portion having a plurality of parallel lines; a second parallel portion arranged perpendicular to the first parallel portion so as to form a plurality of square-shaped cells, and including a plurality of parallel lines; and a circular cross-reinforcing portion including a portion in which the first parallel portion and the second parallel portion intersect.
