Description

Multi-Layer Metal Insulation (MLMI) can be used to create the thermal barrier desired by the Navy in order to dissipate or deflect the jet blast from aircraft taking off. MLMI is multiple layers of sheet metal separated by corrugation that are held together metallurgically, but are thin enough (low density) where there’s not a substantial amount of heat that can be held within. Whatever heat is transferred can be readily dissipated into the environment within moments via convection, conduction, and forced convection as the blast moves away from the JBD. Key to this MLMI is the use of high temperature alloys as the first layer with a melt point above 4,000°F and is corrosion resistant to seawater. Sublayers can transition to other materials that can be titanium, a corrosion resistant material with very low thermal conductivity. The number of layers is key in holding off the standoff temperatures from the jet blast to the aluminum deck underneath. Just for the same reason you can pull aluminum foil from a hot oven, MLMI can deflect the blast from a departing aircraft and then allow, within a short moment, for another aircraft to rollover.
