The DarkAero 1 prototype will use a firewall made from titanium sheet metal, ceramic insulation, and a honeycomb sandwich panel. We discuss why we selected at this material combination and show some testing of how our firewall might perform in the unlikely event of an engine fire. We also cover how our design relates to FAA regulations for certified aircraft firewalls, particularly FAR 23.1191.
