Abstract:This report summarizes the research effort undertaken by the Federal Aviation Administration (FAA) to develop an improved test methodology for determining the performance of aircraft evacuation slide materials when exposed to radiant heat. A laboratory-scale test method was previously developed by the FAA circa 1983, which used a pressurized cylinder apparatus on which a sample of evacuation slide material is mounted. The slide sample material was exposed to an electrically powered radiant heat source that simulated the heat flux typical of a fully developed jet fuel fire. The purpose of the test was to determine the ability of an evacuation slide to maintain pressurization when the material was exposed to radiant heat, as past aircraft accidents had shown that evacuation slides were losing pressure prematurely during exposure to jet fuel fires.
