The fire or explosion of the aircraft fuel system is one of the main causes of aircraft crash. It is necessary to carry out theoretical and experimental researches on the fire and explosion protection capabilities of aircraft fuel tanks. The fuel inerting system has been developed in recent years. In the use of civil aircraft fuel tank inerting system, whether the optimal inerting efficiency can be achieved is one of the hot issues widely concerned. In order to study the influence of different factors on the inerting characteristics of the fuel tank, a set of aircraft fuel inerting test device was designed and developed firstly to simulate the washing inerting process of the aircraft fuel tank, and then the influence of different inlet flow, concentration and inlet position on the inerting characteristics of the aircraft fuel tank inerting system was explored. The research can provide theoretical guidance and technical support for the further development and application of domestic civil aircraft fuel inerting devices.
