| 摘 要： | 详细描述了液体火箭推进剂（Ｎ２Ｏ４／ＵＤＭＨ）爆炸试验装置及其爆炸热过程特性测量。通过５０ｋｇ、１００ｋｇ、３００ｋｇ三种不同推进剂总质量的爆炸试验，得到了推进剂爆炸火球内部温度场、辐射温度场、辐射热流场和火球直径等热过程特性参数。还分析了热过程特性参数随推进剂总质量、时间和空间位置的变化规律。

| Abstract: | est facility,measurement methods of heat process and measurement system for liquid propellant (N2O4/UDMH) explosion are described.Explosive tests of propellant with three kinds oftotal mass, 50kg,100kg and 300kg,are carried out.Heat process property parameters of explosivefireball Such as internal temperature field, radiant temperature field, radiant heat flux density andfireball diameter are measrued.The effect of total propellant mass,time and location on the heatprocess property parameters are also analysed. |
