基于PyroSim的飞机货舱火灾仿真模拟OA

Taking Boeing 737-800,the most common type of civil airliner in China,as an example,with reference to the relevant experiments of the Federal Aviation Administration(FAA)of the United States,the cargo hold fire during parking is numerically simulated by the simulation software PyroSim,and four conditions of cargo combustion,cargo door closure,wind and dangerous flammable and explosive materials with different loading rates are analyzed.The heat release rate and temperature of cargo hold fire with time are obtained.The simulation results are consistent with the reality and consistent with the relevant experimental data,and the results are analyzed,and some suggestions about aircraft fire prevention are put forward,which provides a reference for the layout and training of airport fire stations and the design of fire alarms.
