飞行器是现代生活中最为便捷和安全的交通运输工具之一,同时也是战争中发挥重要作用的利器之一,其科技含量非常高且结构复杂,细小的疏忽就可能带来机毁人亡的严重后果。装载航空煤油的油箱在飞行器系统部件中属于关键性部件,通过故障模式与影响分析中,燃油泄漏为主要故障模式可造成液体燃烧和爆炸。飞行器在高空飞行状态下航空煤油泄漏后处于低压状态,此时航空煤油的爆炸特性与常压下是不同的,本文通过实验设计考察在低压状态下航空煤油的燃爆特性。
Aircraft is one of the most convenient and safe modes of transportation in modern life. It is also one of the weapons that play an important role in war. Its very high technological content and complex structure and small negligence may lead to serious aircraft crash as a result of. The fuel tank with aviation kerosene is a key part in the aircraft system components. Through the failure mode and impact analysis, the fuel leakage as the main failure mode can cause the liquid to burn and explode. Under the condition of flying at high altitude, the aviation kerosene is in a low pressure state after it leaks. At this time, the explosion characteristic of aviation kerosene is different from that under atmospheric pressure. In this paper, the explosive characteristics of aviation kerosene at low pressure are investigated through experimental design.
