Crash survivable enclosure for flight recorder

摘要: A crash survivable enclosure for flight data recorders used in aircraft and other vehicles operating over land water includes a strong, light-weight metal shell enclosing protecting an information storage device having power, signal, address lines connected thereto. The memory is supported inside the wax filler of type high melting temperature heat fusion to act as sink absorbing large quantity minimize possible damage because excessive heat, flames and/or temperature. strong lightweight provided enclose protect inner contents against substantial, external mechanical forces commonly occurring flames, fire resulting therefrom. second efficiency, insulating material physically supporting providing protection flame, penetration well physical impact shock would be encountered or vehicle carrying enclosure. especially designed withstand prolonged immersion salt at substantial depths provide so that pertinent recorded available upon retrieval after crash.
