考虑了基于仿真生成的数据生成用于与设计相关的飞行动力学研究的表格式气动模型。所描述的框架包含两种设计方案。第一种方法强调气动非线性的表示,并基于采样。第二个场景假设从初始几何图形进行增量更改,其中第一个场景中的高保真模型可用。在这种情况下,使用数据融合来更新模型。在这两种情况下,都使用克里格法对使用模拟计算的样本进行插补。以DATCOM为数据源,计算了一个商用喷气式飞机的测试案例,以说明采样和融合。考虑了使用计算流体动力学作为数据来源的未来应用。
The generation of a tabular aerodynamic model for design related flight dynamics studies, based on simulation generated data, is considered. The framework described accommodates two design scenarios. The first emphasizes the representation of the aerodynamic nonlinearities, and is based on sampling. The second scenario assumes incremental change from an initial geometry, for which a hi-fidelity model from the first scenario is available. In this case data fusion is used to update the model. In both cases, Kriging is used to interpolate the samples computed using simulation. A commercial jet test case, using DATCOM as a source of data, is computed to illustrate the sampling and fusion. Future application using Computational Fluid Dynamics as the source of data is considered.
