本文对液体推进剂四氧化二氮／偏二甲肼（Ｎ２Ｏ４／ＵＤＭＨ）爆炸热过程特性进行了实验与理论研究。研究结果显示出了火球尺寸变化、火球持续时间、火球内部温度、火球辐射热流传递过程等热过程特性参数随推进剂重量、时间和空间位置的变化规律。理论预测结果与实验测量结果相比符合较好，表明理论预测模型的正确性。本文还讨论了火球升离地面的临界条件、高空环境对火球直径的影响和火球随风漂移等三方面的问题。
In this paper, the thermal and thermal properties of liquid propellant N2O4 / UDMH explored experimentally and theoretically. The results show that the parameters of the thermal process, such as the size of the fireball, the duration of the fireball, the internal temperature of the fireball and the heat flux of the radiant heat of the fireball, vary with the weight, time and space position of the propellant. The theoretical prediction results are in good agreement with the experimental ones, indicating the correctness of the theoretical prediction model. The paper also discusses the critical conditions of the fireball rising from the ground, the impact of the upper air environment on the diameter of the fireball, and the drift of the fireball with the wind.
