Design of lightning protection for AFDX network interface

When an aircraft is hit by lightning, it often causes damage and interference to the airborne equipment. AFDX network is usually used as aircraft backbone network in aircraft. When the equipment is not working normally due to lightning stroke, it may cause serious threat to flight safety. This paper introduces the principle of network interface lightning damage, introduced several kinds of common lightning protection devices According to the characteristics of AFDX network interface,carried out the lightning protection design and the test verification.
