摘　　要：目前,军用飞机和民用飞机均广泛采用机载中空膜惰化系统以降低飞机燃油箱燃烧爆炸的危险,但是这种惰化技术存在效率低、对引气压力和流量要求较高的固有缺点,因此,研究者还在寻求更好的惰化技术。将燃油箱上部气相空间的可燃气体在催化反应器中反应来降低氧浓度的方式具有很多独特的优势,近年来得到较大关注。本文在介绍国外第一代耗氧型燃油箱惰化技术的基本原理和研究历史的基础上,对近年来第二代耗氧型惰化技术的最新研究成果进行了介绍,包括其基本结构、系统流程、在FAA及A-3攻击机油箱上的实验测试数据。On-Board Inert Gas Generator System （OBIGGS） is widely used in military and civil aircrafts to reduce the combustion and explosion risk of fuel tanks. Because of inherent disadvantages including low efficiency, high demand to the pressure and flow rate of the bleed air, researchers are still seeking better inerting technologies. A novel technology, in which the flammable gas on ullage is imported into a catalytic reactor to reduce the oxygen concentration, is paid more attentions due to its unique advantages. Based on the introduction of the essential principle and history of the first generation oxygen consumption based fuel tank inerting technology, the latest research contributions of the second generation oxygen consumption based fuel tank inerting technology were presented including its basic structure, system flow and some experimental data measured in FAA and the fuel tank of A-3 attacker.
