Abstract
An algorithm is developed to predict the thermal response of aircraft ceiling materials during a post-crash fire scenario. The scenario involves an aircraft's emergency exit doorway which opens directly onto the flames of an external, fuel-spill fire which engulf a large portion of the fuselage. Data of near-ceiling temperatures acquired during a series of eight, full-scale, wide-body aircraft cabin, post-crash test simulations provide indirect validation of the algorithm. These tests involved cabins outfitted with only single, mockup seats. Two other full-scale cabin tests involving fire spread through twenty-one seat arrays with different types of seat construction provide the input data required to exercise the algorithm in evaluations of fully outfitted cabins. Relative to the post-crash scenario, a measure of cabin fire safety is proposed, viz., the post-crash time-to-ceiling-ignition. This measure would be used as a surrogate for the post-crash time available for passengers to safely evacuate the cabin. In this sense, the algorithm is exercised in an example evaluation of the fire safety of a candidate honeycomb ceiling material used together in cabin systems involving polyurethane cushion seating, with or without a blocking layer.
