飞机维修库防火技术探讨

摘要

分析了飞机维修具有的火灾危险性,探讨引发飞机维修库火灾的原因.针对飞机维修库火灾特点,分析了飞机维修库灭火分区、灭火系统和报警系统,并在建成的某飞机维修库中,模拟飞机机翼下火灾,检验了防火技术.结果表明:火灾报警系统顺利报警,在泡沫-雨淋系统和泡沫炮联合作用下,约6 min后扑灭火灾.%The fire danger and fire cause of maintenance hanger were analyzed. The fire compartment, fire extinguishing system and fire alarm system were analyzed according to the characteristics of maintenance hanger. The fire under aerofoil was simulated in a maintenance hanger to test the fire prevention technology. The results show that the fire alarm system is functional and the fire was putout in 6 min under the united act of foam-water deluge system and foam monitor.
