Abstract

The accumulation and discharge of static electricity on the body of an aircraft in flight is inevitable which leads to interference in communication, Radar, and localizing systems of the aircraft. One of the more applicable and effective methods against this phenomenon is using a null-field static discharger. In this article, the amount of charging current injected into the airfoil has been calculated with empirical formulas. With the electrical field transient analysis on the aircraft body, the points that reach the corona threshold beforehand have been adopted as the discharger mounting areas. By implementing the structure of the null-field static discharger in the software and mounting it in the adopted points, the corona noise is reduced by 32 dB. The simulation results are justified by the experimental results of the references.
