| description | The lightning protection design and verification of aircraft are necessary measures to ensure the safety of pilots and aircraft, especially with the poor lightning protection ability of composite materials. The conductivity of the composite is weaker than that of the metal, which needs to provide additional pathways for the lightning current conduction. Based on the electromagnetic modeling of aircraft internal structure rarely mentioned in domestic related research, a set of electromagnetic modeling and precision control method for aircraft internal structure is proposed, and the internal metal structure from left wing to right wing of F22 aircraft is constructed as lightning current conduction path. The indirect effect of aircraft lightning is simulated based on general electromagnetic simulation software. The simulation results of electromagnetic field and cable coupling in aircraft interior under three conditions of composite skin, metal mesh skin, and metal mesh skin with internal metal structure are compared. The results show that the reasonable lightning current conduction path design can reduce the current intensity induced by the cable inside the aircraft by half, and play a good lightning protection effect. The proposed evaluation method is suitable for the lightning current conduction path design of fixed wing aircraft, can be taken as the indexes distribution reference frame of aircraft airborne equipment lightning indirect effect test, and is convenient for locating the weak links of aircraft lightning indirect effect protection. |
