“…Maximum-scaled values for the plasma pressure, velocity and temperature versus time are also presented in Figure 8. The temperature results demonstrates that despite the air plasma core temperature being in the range of 10,000 K the cathode and anode surface temperature is only in the range of 300 K. This is due to the short time duration of the lightning strike event and is validated by experimental results [37,38,39] in which the cathode surface is not evaporated. Moreover, in certain lightning strike test setups a rubber head is installed near the cathode to reduce the lightning strike channel expansion pressure effects and again the rubber head is not typically damaged by heat.…”

A numerical approach is proposed and demonstrated for efficient modelling of the thermal plasma behaviour present during a lightning strike event. The approach focuses on events with time-scales from microseconds to milliseconds and combines the finite element method, Magnetohydrodynamics and Similitude theory. Similitude theory is used to scale the problem to require considerably less computing resource. To further reduce the computational burden and to resolve the numerical difficulty of simulating the nearly zero electrical conductivity of air at room temperature an approach based on cold field electron emissions is introduced. Simulations considering turbulent flow have been considered, modelling a test configuration from literature designed to inspect composite material performance and applying an aerospace standard test profile (waveform-B). Predicted peak temperatures (of the order of ~40,000 K) and pressures (of the order of 0.1-0.2 MPa) suggest that the pressure loading during a waveform-B event will have a minimal effect on composite material damage.

“…The lightning strike experimental configuration simulated is similar to the one used by Hirano et al [37], Ogasawara et al [38], and Feraboli & Miller [39] to inspect composite material performance. The calculation domain and boundary conditions are shown in Figure 2 and Table 3.…”

“…An integral fuel tank has the advantage of partially balancing the lift force generated by the delamination area also matches qualitatively well with the experimentally obtained ultrasonic C-scan results in [14]. Since the tool is valid for CFRP composites, it may also be used for the same type of analysis on CFRP composites of different geometries.…”

A lightning strike to the aircraft seriously affects the aircraft and its components in various ways. As one of the most critical threats to the flight safety of an aircraft, fuel vapour ignition by lightning can occur through various means, notably through hot spot formation on the fuel tank skins. In this study, a coupled thermal-electrical approach using the commercial software ABAQUS is used to study the effects of a lightning strike on aircraft fuel tanks. This approach assumes that the electrical conductivity of a material depends on temperature, and that a temperature rise in a material due to Joule heat generation depends on electrical current. The inter-dependence of thermal and electrical properties-the thermal-electrical couplingis analyzed by a coupled thermal-electrical analysis module. The analysis elucidates the effects of different material properties and thicknesses of tank skins and identifies the worst case of lightning zones.
