| 摘 要： | 采用重叠网格技术,通过求解Navier-Stokes方程,对飞行器起飞状态下增升装置的地面效应进行了数值模拟.选取GAW-1为基本翼型进行增升装置设计,进一步生成重叠网格,分别采用“虚拟运动地面”模式边界条件进行了计及地面效应定常流场数值模拟,以及飞行器运动模式进行了计及地面效应的非定常流场数值模拟.对比分析了不同数值模拟方法之间对气动特性以及流场的影响,为飞行器地面效应数值模拟提供了参考.

| Abstract: | Navier-Stokes was taken as master equations,steady/unsteady flowfield of aircraft ground effect has been simulated based on chimera grid.GAW—1 airfoil was taken as base shape to design highlift device,then the chimera grid was generated,steady/unsteady flowfield of aircraft ground effect has been simulated based on "dummy movement ground " and movement wall boundary conditions respectively.The difference between steady and unsteady simulation is compared and analyzed,Correlative referrence is provided for ground effect numeric simulation. |

| Keywords: | ground effect boundary condition chinera grid steady/unsteady numeric simulation highlift device |
