Evaluation of Insulation for Crash Fire Protection of New Flight Recorders

摘要

The work performed under this project involved the evaluation of flight recorder insulation arrangements relative to their ability to provide thermal protection for record tapes under conditions of crask fire. The evaluation encompassed fire testing four different types of insulation arrangements in accordance with three different time-temperature fire environments. It was found that a combination of high-temperature insulation and a heat sink material employing water as the heat absorber provided the best protection for the record tapes when exposed to a realistic severe thermal environment.
