摘要
电线电缆作为飞机上重要的材料,其防火阻燃性能的品质影响飞机的安全性。分析适航规章CCAR-25-R4在线缆防火性能方面的要求,总结当前国内外航空用标准/规范在电线电缆防火性能方面的规定;针对电线电缆防火性能的适航问题进行研究,给出适航工作的验证思路。对于飞机上使用的线缆,采用国外先进企业内部标准制定线缆的性能指标,能够降低适航验证风险,为线缆的选取和使用提供参考。
The wire and cable as the important material of aircraft,its quality of fire resistance performance influences the safety of aircraft.The requirement of wire and cable’s fire resistance performance in airworthiness regulation CCAR-25-R4 is analyzed,and the regulations of domestic and overseas aviation standards and specifications in wire and cable’s fire resistance performance are summarized.The airworthiness problem of wire and cable’s fire resistance performance is studied,and some suggestions of airworthiness work are given.The cable performance index made by foreign advanced inner-enterprise standards can decrease the airworthiness verification risk for cable used in aircraft,and provide the reference for the selection and usage of wire and cable.
