Abstract

Abstract: The metal wire mesh is usually adopted to prevent the lightning stroke on composite materials. The effects of different materials and different thickness of metal mesh on helicopter lightning electromagnetic effect are compared. According to the method recommended by SAE-ARP5416, a numerical simulation software is used for carrying out the high current injection simulation. The results show that the surface mount metal mesh can effectively reduce the harm of lightning electromagnetic coupling effect; the difference between aluminum and copper on anti-lightning stroke effect is not obvious; when the thickness of aluminum grid is less than 0.15 mm, the aluminum on anti-lightning stroke effect is enhanced with thickness increasing; when the thickness is more than 0.15 mm, the value tends to smooth. It is recommended to select aluminum mesh as a helicopter composite conductive layer, and the thickness is at 0.15 mm.
