采用点火模拟试验方法 ,对新型 L OVA发射药的点火性能进行了研究 ;提出了一种预估发射药点火难易的方法。结果表明 :在相同的试验条件下该 L OVA发射药较单基药难点燃 ;在密闭爆发器实验中延迟时间短的发射药相应地在点火实验中较容易点燃。
The ignition performance of the new LOVA propellant was studied by using the ignition simulation test method. A method to predict ignition difficulty of propellant was proposed. The results show that under the same experimental conditions, the LOVA propellant is more difficult to ignite than a single propellant. The propellant with short delay time in the closed explosive experiment is correspondingly more easily ignited in the ignition experiment.
