| 摘 要： | 基于无限插值理论和多块网格技术,生成了带多姿控发动机的拦截弹结构体网格。利用非定常N-S方程数值求解技术,计算了大气层内高超音速拦截弹带多个横向喷流的瞬态干扰流场,为拦截弹瞬态多侧向喷流的精确控制力建模提供了理论参考依据。研究结果表明,与单喷瞬态干扰相比,瞬态多侧向喷流干扰延迟效应更明显;多侧喷瞬态喷流尾流对尾翼存在更强干扰现象。

| Abstract: | Based on infinite interpolation theory and multi-block grid technique,construction grid of interceptor missile with multiple attitude control motors was generated.Transient interaction flow field of the multi-lateral jet hypersonic interceptor in the aerosphere was calculated by means of unsteady Navier-Stokes equations.The calculation results can provide theoretical reference to building precise control force model of the multi-lateral jet interceptor.Compared with transient interaction of single jet,the delay effect of transient interaction for multi-lateral jet interceptor is much more obvious;interaction effect of transient multi-lateral jet flow on tail is more serious. |
