Numerical Simulations
This project studied the thermal and electromagnetic behavior in aircrafts made of composites when it is reached by an atmospheric discharges with the purpose of increasing the resistence of the aircraft against the atmospheric discharges without any mass’ increase of this one and with an affordable cost.
Electrostatic Simulations:
In order to to vizualize the voltage distribuition in the aircraft after it receives the atmospheric discharge is necessary the electrostatic simulation. This simulation (performed in the GMSH and GETDP simulations) allows the user indicates the problem of the variable like the voltage applied, boundary conditions, materials and etc. After that, the distribution reuslts of the voltage with material and conditions are visualized. The simulations are a way to approximate the specific geometry what could be a real situation.
Thermal Simulations:
The atmospheric discharges make a plenty of effects directly to the composites aircrafts and among them are the fiber delamination, resin vaporation and the thermal decomposition and most of these effects start because of the increase of the temperature caused by the Joule effect when the aircraft is reached by the atmospheric discharge. In that way, it is important to analyze the temperature distribution over the most critical points reachead by this phenomenon. In the LSE the numerical simulations are carried out about these effects using the finite difference method.
