| 摘 要： | 根据飞机设计初级阶段所得到的总体布局参数,建立并估算飞翼布局横航向气动导数的数值计算模型,对模型进行了算例分析,与计算流体力学方法(CFD-FASTRAN)、风洞实验所得的横航向气动导数做了对比分析.结果表明,基于总体布局参数估算的横航向气动导数简洁、快速、合理.

| Abstract: | To estimate the lateral and direction static stability of flying wing,a numerical calculation model of aerodynamic derivatives is developed based on aircraft geometry parameters from the conceptual design phase.An example for aerodynamic derivatives is given.A comparison of the numerical calculation results to predicted aerodynamic derivatives by a computational fluid dynamics(CFD-FASTRAN) method and wind-tunnel testing data shows that the numerical calculation method based on an aerodynamic configuration g... |
