摘要
飞机燃油箱起火或爆炸是导致飞机失事的主要原因之一,在民用飞机燃油箱惰化系统使用过程中,能否实现最优惰化效率是广受关注的热点问题之一。为了研究不同影响因素对飞机燃油箱惰化特性的影响,研制了一套飞机燃油惰化试验装置,模拟飞机燃油箱冲洗惰化过程,探究了不同进气流量、浓度以及进气口位置对飞机燃油箱惰化系统惰化特性的影响情况。
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.
