ABSTRACT:
A crash survivable protective enclosure for flight data recorders, cockpit voice recorders and memory devices employing a solid state memory element includes a conformal coating of air excluding plastic material around the memory element. An inner shell of metal having a low position on the periodic table in comparison to tin and copper associated with the memory element is provided to enclose the memory element and the conformal coating. Heat insulating fillers are provided around the inner metal shell which serves as a sacrificial anode when the enclosure is exposed to salt water. An outer metal shell formed of high strength material is provided around the insulating filler for resisting physical forces applied from an exterior of the protective enclosure during a crash.
