Operational sensitivities of military air craft, deterrent measures in aircraft design to prevent the accumulation of static charge on the surface of the aircraft or Electrostatic Discharge, is very necessary and important. These include antistatic coatings, flame spraying, the use of carbon fiber composites and nanocomposites in aircraft fuselage design, and electrostatic dischargers. The aim of this study was to investigate, simulate and compare the effect of electrostatic discharge (ESD) in military aircraft with all-metal, all-composite body and the combined state of several structures. In this paper, by selecting the military Aircraft body of composite, metal and combined mode, the effects and surface of induced electric field, surface currents due to electrostatic flux and Radiation electromagnetic fields from the transient state of surface current will be compared and examined in different parts of the military air craft, including: radar system, cabin and electronic telecommunication systems, internal and external fuel tank.

The main objective of this research is to improve the distribution of electrical potential on spacecraft surfaces by changing the surface coatings to reduce the risk of electrostatic discharge in the spacecraft. For this purpose, SPIS software, the EU standard software for modeling and simulating the interaction of space plasma with the spacecraft is used. The spacecraft has 8 nodes, and each node is related to a particular substance. The simulations were compared with the variation in the materials of these nodes in terms of differential electric and floating potential. Investigating materials that differed in the differential electric potential of zero showed that they are conductive materials. In order to choose among several conductive materials, these materials were compared in terms of electric floating potential. Simulations on satellite surfaces showed an average of 11% improvement in the electrical potential on surfaces
