摘　　要：针对潜艇水平发射飞行器,发射后飞行器故障无法点火,对潜艇安全威胁很大的问题,通过水弹道仿真研究发射艇速对艇弹安全性的影响,详细分析了潜艇水平发射飞行器的水下力学环境,重点研究了海流粘性力及艇艏扰流干扰力计算方法,建立了飞行器水弹道数学模型。通过试验弹道数据与弹道仿真数据直接比对方法,对水弹道仿真模型进行了有效性验证。进行仿真试验设计,仿真分析飞行器不点火故障情况发射艇速对碰艇的影响。研究方法也可用于水下航行器水弹道预报及仿真研究。The design of the water trajectory is the key technical problem in the design of the underwater vehicle. The simulation of the water trajectory is an important means in the design and p^diction of the trajectory, and is the main method to analyze the security threat of the submarine. To study the security threats of the submarine caused by the ignition failure of the marine horizontal launched vehicle, the simulation of the water trajectory is carried out, and the impact of the submarine speed, sea current and wave on the security of the submarine is investigated. The underwater mechanical environment of the marine horizontal launched is analyzed in detail, and the viscous force of the sea current and the force of the disturbance flow of the bow is investigated in special, and the mathematical model of the water trajectory is established. Then the ignition failure problem of the vehicle and the impact of the submarine speed, sea current and wave on the submarine hitting are simulated. The method can be implemented in the p^diction of the trajectory of the underwater vehicle and the simulation.
