Aircraft Lightning Direct And Indirect Effects Of Experimental Research

The energy and LEMP of lighting often bring about flight accidents of the aircrafts, and almost of the accidents are disasters. In another hand, according to the use of new concept weapons such as weapons of LEMP, it is the truth that military crafts were attacked in possible battlegrounds or fighting environments. If it hasn't been kept watch, it were be fatal when crafts being attacked. Obviously, it the problems of affect the lighting LEMP to the aircrafts could be settled, in some high, it were been eliminated or lightened the other environments of LEMP to the aircrafts.The article makes some researches to the characteristics of lighting and the protect of lighting. The major research of this paper is about the types,process and characteristics of lighting, and simulating the situation of the aircraft which stoke by lighting in laboratory.At first, The article introduces the fundamental principle of lighting, analyses the characteristics of the four periods of the lighting in emphasis, then According GJB3567-99《military aircraft protect check test methods》,GJB2639-96《military aircraft lighting protect》standard, designs the model of the test and circuits of the test. In laboratory, We use the simulating lighting to test the affect of lighting current, and make E-wave and A-wave test of lighting with aircraft, up to the area of lighting sticking, let the simulating lighting current enters into or leaves the test part through the typical way it is particularly easy suffer the lighting. measuring a lot of datas about the characteristics of the distribution and intensity of the inner lighting electromagnetic field, and analyses the datas, makes the conclusion of the test, then proves the safety and reliability of aircraft in lighting environment, supply further study basis of protect design of lighting and protect design of lighting, ultimately supply to demands of lighting protect check test, so test indexes of aircraft protect design.
