The high resistivity of composite materials will affect the original conductive path of the aircraft, in order to ensure the normal operation of the aircraft electrical system, it is necessary to construct a composite aircraft electrical structure network system model to explore its electrical characteristics. Firstly, for the calculation of the electrical characteristics of the electrical structure network under electromagnetic field, this paper adopts the finite element method and the sta-ble double conjugate gradient method to jointly construct the electrical structure network system model, and the optimi-sation value of the calculation space reaches 63.92%. Secondly, by exploring the combination of multi-type excitation sources/multi-area access points, the multi-dimensional electrical results and performance impacts, such as area im-pedance characteristics, potential distribution profiles, and current density vectors, are analyzed. By constructing and measuring the physical model, the difference between the measured and simulated results is analyzed, and the compli-ance with the airworthiness regulation HB 6129 is verified. Finally, based on the actual working condition perspective and airworthiness regulation, the system model is analyzed for contact factor system error, refined ideal model analysis and component stress factor analysis. The obtained results and analyses are of great significance for the electrical performance index of composite/electric aircraft.
