Abstract : The purpose of the study is to investigate concepts and recommend practical means to lengthen the fire survival capability of airborne magnetic tape crash recorders. As directed, the time temperature profile is assumed to be 200 degrees F for 2 hours, decreasing to 500 degrees F in the next 6 hours and remaining at 500 degrees F for the next 16 hours for a total heat exposure of 24 hours. The study analytically investigates the internal recorder temperature for one, two and six sided heating. Off-the-shelf commercial insulations and some experimental insulations were reviewed and evaluated. (Author)
