An Experimental and Theoretical Investigation of an NEMP (Nuclear Electromagnetic Pulse Simulator) Type Fast Rise Lightning Simulator.

Abstract

Recent lightning phenomena investigations have indicated lightning currents for the high current return phase of lightning strikes to ground of 100 nanoseconds, an order of magnitude faster than the previously accepted value of one to two microseconds. An experimental investigation was undertaken to evaluate the feasibility of using NEMP type generators to provide the faster rise times for lightning testing of aircraft. The program consisted of (a), a theoretical phase to examine the required generator parameters, (b) a low level 300 kilovolt experimental phase with a 30 foot long cylinder, six feet in diameter to represent an idealized aircraft under test and (c), a final phase in which a design was developed for testing of full size aircraft at the test current level of 40,000 amperes.
