摘　　要：为了降低飞机燃油箱可燃性,绝大部分民用和军用飞机都安装了油箱惰化系统,来控制油箱无油空间的氧气浓度,但却一直没有适用于机载燃油箱的氧浓度实时监测系统。根据多型机油箱惰化系统试飞经验,总结了基于电化学原理和光谱吸收原理测量系统使用中的问题。依据文献分析,认为基于荧光猝灭原理的传感器将成为下一代机载油箱氧浓度测量系统的核心,并详细介绍了荧光猝灭效应的原理、检测方法、受感部和测量系统框架的研究现状。最后,指出测量系统应该向着轻量化、智能化和高可靠性方向发展。In order to reduce the flammability of aircraft fuel tank,most civil and military aircraft have installed fuel tank inerting system to control the oxygen concentration of aircraft fuel tank ullage,but there is not real-time monitoring system for the oxygen concentration of the fuel tank on board.According to the flight test experience of the multi-type engine fuel tank inerting system,the problems in the use of measurement system based on electrochemical principle and spectral absorption principle are summarized.According to the literature analysis,it is believed that the sensor based on the principle of fluorescence quenching will become the core of next generation oxygen concentration measurement system in the airborne fuel tank.The principle,detection methods,sensing parts of fluorescence quenching effect and the research status of the test system framework are introduced in detail.Finally,it is pointed out that the measurement system should be developed towards lightweight,intelligent and high reliability.
