AI Technical Summary
Existing technologies make it difficult to efficiently and accurately perform electromagnetic modeling of aircraft fuel tanks, which leads to difficulties in the rapid evaluation and iteration of lightning protection designs and makes it impossible to realistically simulate the distribution of lightning current.
By constructing an electromagnetic prototype based on conduction impedance, the simplified electromagnetic model is gradually adjusted to match the test data, including the conduction impedance simulation of adjacent fastening bolts, components, and individual parts, until a high-precision electromagnetic prototype of the fuel tank is obtained.
It achieves high-precision electromagnetic modeling of aircraft fuel tanks, enabling realistic simulation of lightning current distribution, providing a reliable basis for lightning protection design of fuel tanks, and is applicable to electromagnetic prototyping of various types of fuel tanks and internal components.
