基于三维紊流场相关函数矩阵用蒙特卡罗法仿真生成三维空间大气紊流场 ,并用理论证明和紊流场数值检验的方法 ,证明这样的空间大气紊流场较好地符合所选用的大气紊流模型 (如 Dryden模型 ) ,且具有良好的均匀性和各向同性。三维空间大气紊流场可用于飞机飞行仿真 ,尤其是多架飞机在大气紊流中飞行的仿真 (如空中加油、编队飞行 )。
Based on the three-dimensional turbulence field correlation function matrix, Monte Carlo method was used to simulate the atmospheric turbulence field in three-dimensional space. The theoretical and numerical results of the turbulent flow field were used to prove that the turbulence field in this space is in good agreement with the selected atmosphere Turbulence model (such as Dryden model), and has good uniformity and isotropy. Three-dimensional atmospheric turbulence field can be used for aircraft flight simulation, especially the simulation of multiple aircraft flight in atmospheric turbulence (such as air refueling, formation flight).
