Simulated lightning tests on external fuel tank of aircraft

Abstract

Laboratory setup and test configuration for lightning testing of fuel tank are described. The test was performed in accordance with test method specified in MIL-STD-1757A. The results of the test indicate that arcs/sparks occur at various locations such as observation window, bulkhead-to-skin gaps, and the fasteners associated with various valves. Lightning protection designs to suppress area/sparks are also discussed.<>
