摘要
基于国产民用飞机适航符合性评估需要,简要总结了FAA修订FAR25.981适航规章发展变迁,收集了国内外不同燃油海平面闪点数据,通过蒙特卡洛可燃性暴露分析程序,得到了闪点平均值和标准差变化对油箱可燃暴露率的影响。结果表明:闪点平均温度值越大,标准差范围越宽,油箱可燃性暴露率也越大,在相同条件下,飞机使用RP-3燃油的可燃性暴露率高于Jet A燃油,因此在我国飞机在适航审定过程中应当充分考虑燃油差异对可燃性的影响,完善适合我国国情的适航审定标准和规范。
Based on the airworthiness conformity assessment needs of domestic civil aircraft,the development and changes of airworthiness regulations of FAR25.981 revised by FAA were studied,and the fuel flash point temperature ranges at home and abroad were investigated.Through monte Carlo flammability exposure analysis program,the impact of the average flash point and range changes on fuel tank flammability exposure rate was obtained.Results showed that the larger average flash point temperature value indicated the wider standard deviation range,and the larger flammability exposure rate of fuel tank.Under the same conditions,the flammability exposure rate of aircraft using RP-3 fuel was higher than that of Jet A fuel.Therefore,the impact of fuel differences on flammability should be fully considered in the airworthiness certification process of aircraft in China,and the airworthiness application standards and specifications suitable for China’s national conditions should be improved.
