| 摘 要： | 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)。

| Abstract: | This study is concerned with Monte Carlo simulation for three dimensional field of atmospheric turbulence, in view of correlation function matrix. This atmospheric turbulence field, which is homogeneous and isotropic, is identical with the Dryden model by theoretical proof and numerical test. This 3 D field could be used for aircraft flights simulation, especially for simulation of several aircraft flights in atmospheric turbulence (such as air refueling and formation flight). |
