摘　　要：针对民用飞机燃油箱微生物污染问题,对油箱内常见的微生物进行分类,并研究其在燃油箱中的生长条件和机理,分析其对油箱结构、燃油系统和发动机的功能、性能、安全等影响,并总结针对飞机研制和生产阶段,在燃油箱结构设计、燃油系统设计上提出了微生物污染的防护设计要求,针对飞机运营和维护阶段,在勤务和停放等方面提出了微生物污染的预防与监控措施。在飞机生命周期的研制阶段对燃油箱微生物进行预防设计,在飞机生命周期的运营阶段对燃油箱微生物进行持续监控,可有效提高民用飞机燃油箱防微生物污染能力。To address the microbial contamination of civil aircraft fuel tanks,the common microorganisms in the fuel tanks were classified.The growth condition and the growth mechanisms of microbial contamination in the civil aircraft fuel tanks were studied.The impact on the function,performance and safety of the aircraft structure,the fuel system and the power plant system were analyzed.For aircraft development and production stage,the microbial contamination protection design requirements of microorganisms were summarized in terms of the structural design of the fuel tanks and the design of the fuel system.For aircraft operation and storage stage,the prevention and monitoring measures requirements of microorganisms were put forward for service and maintenance.The preventive design and continuous monitoring of microorganisms during the life cycle of civil aircraft will effectively improve the ability of civil aircraft fuel tanks to prevent microbial contamination.
