The indirect effect test system of H wave of vehicle-borne lightning

When the aircraft (aircraft, missile, rocket, reentry spacecraft, etc.) is flying in the air, the charged cloud will discharge to the aircraft and its surrounding clouds, generating discharge current wave of thousands of amps and rising time in nanosecond. This system is mainly used to simulate the lightning flow waveform of lightning between clouds (within clouds). It can be used to test the indirect effect caused by direct lightning on aircraft or other equipment, so as to determine whether the aircraft's internal electronic instruments can work reliably when it is exposed to the direct effect of lightning between clouds.
