摘　　要：为分析投放条件对入水参数的影响,建立了弹伞系统纵平面内的弹道数学模型,利用Matlab/Simu-link软件对入水参数随投弹参数的变化进行了仿真,并针对满足正态分布的投弹参数对入水参数的散布影响做了进一步的分析,结果表明:投放高度在较低高度时对入水参数的影响较为明显,而投放速度对物体偏离投放点的距离影响较大,投弹姿态角对入水参数的影响甚微。In order to analyze the effect of dropping condition on water-entry parameters,the mathematical model of longitudinal trajectory for the parachute and object system was established Then,the Matlab/Simulink was used to carry on simulation research for the water-entry parameters under the influence of delivery parameters,and further analysis was made for the effect of delivery parameters in normal distribution on distribution of water-entry parameters.The result indicates that the delivery altitude not far above the ground plays an important role in water-entry parameters.The water-entry position is mostly affected by delivery velocity.Delivery carriage has little influence on water-entry parameters.
