以激光辐照旋转飞行靶为研究背景,考虑激光的大气传输,以及激光辐照面积和功率密度分布随靶目标旋转和飞行的变化,建立激光辐照热传导模型;利用有限容积法,得到靶目标三维温度场的数值解;分析目标旋转速率对温度场分布以及炸药热爆炸的影响。分析结果表明:靶目标旋转速率越大,靶表面最高温度值越小,热量越不容易集中,越不利于炸药的热起爆。
以激光輻照鏇轉飛行靶為研究揹景,攷慮激光的大氣傳輸,以及激光輻照麵積和功率密度分佈隨靶目標鏇轉和飛行的變化,建立激光輻照熱傳導模型;利用有限容積法,得到靶目標三維溫度場的數值解;分析目標鏇轉速率對溫度場分佈以及炸藥熱爆炸的影響。分析結果錶明:靶目標鏇轉速率越大,靶錶麵最高溫度值越小,熱量越不容易集中,越不利于炸藥的熱起爆。

Taking laser irradiating rolling flying target as the background ,the heat conduction model is established ,w hich includes the influences of atmosphere transmission ,and varying irradia-ting area and power destiny distributing as target flying and rolling . The numerical simulation of three-dimensional temperature field of flying target is calculated by the finite volume method .The in-fluences of rolling velocity to temperature field and thermal explosion are analyzed .The analytical re-sults show that the highest temperature of column surface becomes smaller ,the energy concentration and explosion of the explosive becomes more difficult as rolling velocity of target is greater .
