Investigation of susceptibility of airborne equipment to high transient magnetic fields was conducted in a high current- and in a high voltage laboratory. Metal test cylinders were subjected to current impulses, up to 15 kA, simulating high surge currents, representing directed energy applications or lightning strokes. The cylinder used in the high current laboratory is made of aluminum and is representative in size and construction of an aircraft fuselage. Surge current measurements, dBdt measurements outside and inside the test cylinders B is the magnetic flux density, and the measured effects of apertures open or closed are described in the paper.
