Measurements and Theoretical Analysis of a Full Scale NEMP Type Lightning Simulator for Aerospace Vehicles
Abstract
In an earlier paper, it was suggested that peaking capacitors such as are used in nuclear electromagnetic pulse simulators be used to supply the fast current rise times which have been indicated in recent researches in the field of lightning spherics and lightning quantitative experimental and analytical study has been undertaken to examine the feasibility and the significant parameters for such a system. The results of the studies have indicated that average lightning currents of 20,000 to 40,000 amperes, with moderately fast rise times of 100 nanoseconds (which is an order of magnitude improvement), can be achieved fairly economically, but that rise times of the order of 30 to 50 nanoseconds would increase the cost and design difficulties significantly. What remains to be determined is the statistical distribution of currents and risetimes in strikes to aircraft. A number of flight research programs are currently underway which are accumulating data for establishment of new rise time test standards.
