【摘要】：为研究烤燃对不填充和填充球形抑爆材料燃油箱的破坏效应,正确评估抑爆球的阻燃抑爆效果,模拟车辆、飞机的燃油箱受到炙烤的场景,对盛装-10号柴油(-10PD)、喷气燃料(RP-5)的油箱进行烤燃实验,并采用摄像机、高速照相机、红外热成像仪和热通量计等分别记录和测量了油箱的烤燃过程及其产生的喷射火球尺寸、表面温度和热辐射参数。结果表明:油箱在烤燃过程中将产生喷射火,甚至发生蒸气云爆炸,其破坏效应主要表现为喷射火球的热效应。对于填充抑爆球的-10PD、RP-5油箱,其油料受热初始燃烧的时间分别延迟了48 s和121 s,喷射火球的最大截面积分别减小了65.72%、42.44%,表面最高温度分别减小了26.13%、12.66%,其热通量伤害后果也明显减小。
[Abstract]:In order to study the damage effect of roasting on unfilled and filled spherical fuel tank, correctly evaluate the flame retardancy and explosion suppression effect of explosion suppression ball, simulate the vehicle, the fuel tank of aircraft was scorched, and filled with-10 diesel oil (- 10PD), The roasting experiment of jet fuel (RP-5) fuel tank was carried out, and the baking process and the size of the injection fireball were recorded and measured by the camera, high-speed camera, infrared thermal imager and heat flux meter respectively. Surface temperature and thermal radiation parameters. The results show that the fuel tank will produce jet fire and even vapor cloud explosion in the process of baking and burning. The main damage effect of the fuel tank is the thermal effect of the jet fireball. For -10PDN RP-5 fuel tank filled with explosion suppression ball, the initial combustion time of oil was delayed by 48 s and 121 s, respectively, and the maximum cross section area of injection fireball was reduced by 65.72% and 42.44 s, respectively. The maximum surface temperature was reduced by 26.13 and 12.66, respectively, and the heat flux injury effect was also significantly reduced.
