摘要
为优化某飞行器气动外形结构,基于商业软件ANSYS/FLUENT进行网络建模、飞行器流场模拟、气动数据分析,求解出飞行器在0~20°攻角范围内的升力系数和阻力系数。将计算结果同试验数据进行对比,结果表明,升力系数和阻力系数同试验基本一致,说明采用FLUENT建立该模型进行飞行器气动计算方法可行,可为飞行器外形优化提供参考。
To optimize the aerodynamic external structure of a certain aircraft,a network model was built using the commercial software ANSYS/FLUENT.The flow field simulation and analysis of aerodynamic data for the aircraft were conducted,and the lift coefficient and drag coeficient within the range of 0°to 20°angle of attack were obtained.The calculated results were compared with experimental data,and the results showed that the lift coefficient and drag coeficient were in good agreement with the experiment,indicating the feasibility of using FLUENT to establish the model for aerodynamic calculations of the aircraft.It can provide reference for the optimization of the aircraft's external shape.
