【 摘 要 】

This article comprehensively addresses the problems associated with the structure of recurrent circuits of military aircraft with metal fuselage structure. The authors describe the issues concerning the usage of the fuselage as a recurrent circuit of electric current and with negative conductors connecting the fuselage with negative terminals of the receiver or the source. The military aircraft are frequently operated under harsh conditions of increased humidity, dustiness and variable temperatures. All these factors as mentioned above contribute to the occurrence of intensive electrochemical corrosion at the contact points of airframe’s elements or electrical conductors’ with the fuselage. Such contact surfaces should be subject to monitoring – AFIT has developed the numerous procedures for each aircraft.
