摘要
涵道本体气动特性直接影响着涵道飞行器的动力性能。文中对影响涵道气动特性的结构参数进行了量化,并使用自适应笛卡尔网格对仿真模型进行了网格划分以提高解算的速度和精度,随后采用Jameson有限体积法对具有不同结构参数的涵道模型进行了仿真研究,通过对仿真结果进行对比分析,得到了涵道本体结构参数与涵道飞行器升力特性间的对应关系。
The duct aerodynamics greatly affect lift characteristics of ducted fan aircraft. The structure parameters which affect aerodynamic characteristics of duct were quantized and the duct model was meshed by using adaptive Cartesian grid. Jameson FVM was used to analyze different styles of duet. According to the results of simulation, several conclu; sions of relationship between duct structure and ducted fan aircraft were made to support ducted fan aircraft design.
