伞降战斗部毁伤试验落点预测方法研究

针对伞降战斗部空投试验时落点受初始状态和外部环境影响较大的问题，开展了试验落点预测方法研究。建立降落伞-战斗部系统的6自由度动力学模型，基于该模型和战斗部初始摆动角度、试验区域风场以及投放高度等信息对战斗部降落过程进行分析，得出了伞降战斗部落点的准确预测结果。结果表明：所提方法可以指导试验人员调整投放位置，实现战斗部在检测仪器的有效测量区域内落地爆炸，提高试验效率和试验安全性；该方法实现了战斗部落点的准确预测，可以用于指导实际战斗部爆炸试验。

Accurate Landing Point Prediction of Warhead Airdrop Test

For the problem that the landing point of the parachute-warhead is affected by the initial state and external environment when the parachute-warhead is dropped by a tethered hot-air balloon, a prediction method of landing point is studied, a 6-DOF dynamic model of parachute-warhead system is established, and the landing process of warhead is analyzed based on the dynamic model, the initial swing angle of warhead, the wind field in the test area and the initial altitude of the warhead. The accurate prediction result of landing point parachute-warhead is obtained. The proposed method can be used to adjust the dropping position to make sure that the landing point of warhead is in the working area of testing instruments, and improve the efficiency and safety of damage test. The airdrop test results show that the proposed method can accurately predict the landing point and can be utilized to guide the actual warhead damage test. Key
