潜射巡航导弹水下发射非定常特性研究

摘要

when a cruise missile is launched underwater, the interfering factors are great and random, and the parameters of the ballistic trajectory change so much. Firstly, In this paper, the impact mechanism of the environment to the missile’s movement underwater has been analyzed. Then specific simulating models have been given and verified according to the characteristics of difference effecting factors. There is a conclusion that the missile’s moving models and environmental models based on the computationalfluid dynamics theories and FLUENT simulating platform are useful in solving the non-linear and unsteady problems.%潜射巡航导弹水下发射呈现出干扰量大、干扰因素随机性大、弹道参数变化急剧等特点，本文首先分析了水下发射环境对导弹水下运动的影响机理。进而针对不同影响因素的特点，提出了具体仿真模型的构建方法并进行了验证。通过以上分析，本文认为基于计算流体力学理论，通过FLUENT仿真平台构建导弹水下运动模型及水下环境模型的方法，能够在一定程度上解决导弹水下发射的非线性非定常问题。
