液体运载火箭爆炸冲击波近场危害性定量评估方法研究

嫦娥四号探测器首次采用了我国自主研制的同位素热源装置，为有效评估运载火箭发生爆炸后，爆炸冲击波对同位素热源装置的危害性，解决同位素热源装置安全设计指标确定难题，开展了液体运载火箭爆炸冲击波近场危害性的评估方法研究，提出了适用于液体运载火箭爆炸冲击波近场危害性评估的爆炸当量、爆炸冲击波峰值超压及作用时间的定量评估模型。

Quantitative Evaluation Method of Near-Field Hazard of Liquid Launch Vehicles Explosion Shock Wave

The CE-4 probe adopted the isotope heat source device independently developed by China for the first time, in order to effectively evaluate the hazard of the explosive shock wave on the isotope heat source device after the explosion failure of the launch vehicle, to solve the difficult problem of determining the safe design index of the isotope heat source device. In this paper, the method of near-field hazard assessment of liquid launch vehicle explosion shock wave is studied, and the quantitative evaluation models of explosion equivalent, peak over-pressure and action time are put forward.
