摘    要:对气动院FL-9低速增压风洞尾撑支架干扰进行数值计算.通过合理的拓扑结构,生成了YF-16模型的分区对接网格.计算对模型的典型安装状态进行研究,获得了全机气动特性和支架干扰量,探讨了此安装状态下弯刀对飞机气动力的干扰特性,并重点研究了Re数对干扰量的影响规律.

关 键 词:尾支架干扰  低速增压风洞  分区对接网格  数值模拟

Abstract:Numerical simulation has been taken to research sting support interference in FL-9 low speed pressurized wind tunnel.We generated multyblock patched grid for YF-16 model by using proper topology configuration.The computation researched sting interference of typical fixing state of model in wind tunnel,influence properties of curve-strut on the airplane' s aerodynamic forces have been discussed.The main point of this investigation is the influence of Reynolds number on these interferences.
Keywords:sting interference  low speed pressurized wind tunnel  zonal patched grid  numerical simulation
