车载导弹垂直发射系统双面导流器

摘要

为研究车载导弹垂直发射过程中燃气射流对双面导流器和周围地面的热冲击和动力冲击效应，采用燃气射流动力学方法，使用网格弹性变形方法和网格再生方法相结合的动网格技术，对导弹发射过程中双面导流器周围的流场进行了数值计算，得到了发射过程中导流器周围流场的温度和压强分布情况。将计算结果与相关实验结果进行对比表明：所用的计算方法是正确可行的，且能够有效保证导弹发射过程中的计算精度及计算效率。%To study the thermo-impact and the dynamic impact effect of jet flow on double-faced deflector and ground during the vertical launch process,the jet flow is simulated based on spring-based smoothing method and remeshing method.The temperature and pressure distribution of the double-faced deflector and around are obtained.Compared with the simulation and relevant experimental results shows that the method is correct and can ensure the missile launching calculation accuracy and efficiency.
