Changes in the Mechanical Characteristics of Alloys under the Action of Lightning Current

Worsening safety of aircraft exposed to lightning discharges is associated, among other things, with a change in the mechanical characteristics of the alloys from which the aircraft fuselage is made. To analyze the impact of discharges on experimental samples, a current-pulse generator has been developed that simulates stages of lightning development. The results of processing the information obtained are presented and conclusions are drawn about changes in the structure and characteristics of the samples studied depending on the discharge parameters.
