Simulation on stealth characteristics of X-tail near space airship

  • 摘要: 为了降低临近空间飞艇的雷达散射截面(RCS)特性,研究了X型尾翼变形角的不同对临近空间飞艇RCS特性的影响.采用物理光学法仿真出X型尾翼不同变形角对临近空间飞艇头向、侧向和尾向RCS特性的影响,并分别采用物理光学法和多层快速多极子法(MLFMM)计算对比球的RCS.对比说明了物理光学法是准确合适的.仿真结果表明,X型尾翼变形角的不同对飞艇头向RCS影响较小,对侧向的RCS影响较大.变形角从0°增加到20°时,侧向RCS减小到0°时的13.7%.X型尾翼的变形可以显著改善临近空间飞艇侧向隐身性能,同时增大了其他方向的RCS.
