    Abstract
  • In order to study the influence of aircraft cabin design on fire protection performance, a concept of fire evacuation safety index (FESI) was firstly presented. The fire scenario and evacuation procedures in aircraft cabin were simulated via simulation software PyroSim and Pathfinder. FESI at different exits were determined under the scenarios of different internal surface area of cabin, width and height of the exit and population. An analysis was conducted to study the influence of such design factors to cabin fire evacuation performance. The maximum populations of several narrow-body aircrafts were determined using back-propagation (BP) neural network in case to ensure the safe evacuation. And an optimized evacuation program was proposed for B737 aircraft. The results reveal that internal surface area of cabin, width and height of the exits and numbers of seats are the design factors that significantly impact cabin fire protection performance. The maximum population of B737-800 under typical layout is 154. However, it may increase to 175 after optimizing to the evacuation program. The proposed concept of FESI not only performs an assessment for the existing aircrafts against fire protection performance and an optimization for cabin layout and evacuation program, but also provides a basis for fire protection design of domestic large aircraft cabin. In addition, it can also provide a reference for other areas of fire research.
