The embodiment of the invention provides an aerodynamic characteristic analysis method and device, electronic equipment and a storage medium, and belongs to the field of data processing. In the method, a component grid of an aircraft model and a background grid corresponding to a target attitude are generated, a lower boundary of the background grid is a ground simulation structure, and an included angle and a distance between an inner boundary and the lower boundary of the background grid respectively represent an attitude angle and a ground clearance of an aircraft. The background grid and the component grid are combined such that the combined grid simulates the flow field environment and attitude of the aircraft while flying near the ground. And further, fluid data simulation is carried out by utilizing a flow field solver, and aerodynamic characteristic data corresponding to the combined grid is calculated. Therefore, the aerodynamic characteristics near the ground do not need to be analyzed through a wind tunnel test means, the analysis cost can be reduced, and the test time consumption can be reduced. Moreover, when aerodynamic characteristics of the aircraft in different attitudes need to be analyzed, only background grids corresponding to the attitudes need to be regenerated, and component grids do not need to be regenerated.

    本申请实施例提出一种气动特性分析方法、装置、电子设备及存储介质,属于数据处理领域。方法中,生成飞行器模型的组件网格和目标姿态对应的背景网格,且背景网格的下边界为地面的模拟结构,背景网络的内边界与下边界间的夹角和距离分别表征飞行器的姿态角和离地距离。将背景网格和组件网格组合,以使组合网格模拟飞行器在近地面飞行时的流场环境和姿态。进而,利用流场求解器进行流体数据模拟,并计算出组合网格对应的气动特性数据。如此,无需通过风洞试验手段来分析近地面时的气动特性,能够降低分析成本,减少试验耗时。并且,在需要分析飞行器不同姿态时的气动特性时,仅需重新生成对应姿态的背景网格,无需重新生成组件网格。
