Abstract

Lightning is a great threat to aircraft flight safety. The lightning protection test of aircraft and the ability of aircraft and its parts to withstand direct and indirect effects are investigated and verified by simulating the real lightning environment in the laboratory. According to the requirements of GJB lightning test, this paper analyzes the lightning grade and introduces several lightning protection designs commonly used in engineer practice.

Keywords

lightning effect, ceramic discharge tube, λ of quarter wavelength, transient voltage suppression diode
