Measured responses of a munitions storage bunker to rocket-triggered lightning
During the summer of 1991, a rocket-triggered lightning test was performed on an earth-covered munitions bunker located at Ft. McClellan, Alabama. Nine negative cloud-to-ground lightning flashes, comprising a total of 38 individual return strokes, were successfully initiated and directed to designated attachment points on the structure. High resolution measurements were simultaneously made of the incident flash currents, both return-stroke and continuing current components, and of responses at 24 test points located throughout the bunker. The response quantities that were recorded included currents, voltages, and electric and magnetic fields. The maximum responses observed at each test point, both as measured and as linearly scaled to median and severe return-stroke incident current amplitudes, are presented and discussed. 8 refs.
