计算流体动力学(CFD)的应用洛克希德·马丁公司在F-22的设计过程中,总是从最容易和最快捷的CFD方法入手,以在限定的时间范围内获得所需要的计算结果。F-22计划的进展速度很快,这就要求所编制的CFD应用程序能快速周转,如能快速生成网络,易于进入巨型计算机使用等,以适应F-22计划的发展速度。该公司主要利用CFD技术起到补充F-22风洞试验工作的作用,如选定合适的布局进行风洞试验;诊断气流流动现象等。CFD还可在F-22进行试验的基础上为公司提供更多的气动数据和求解那些利用风洞试验技术过于复杂和费用过高的问题。
Computational Fluid Dynamics (CFD) Applications Lockheed Martin is always designing the F-22 from the easiest and quickest CFD methods to get the results it needs within a limited time frame . The rapid progress of the F-22 program requires that CFD applications be compiled with fast turnaround, such as rapid network generation and easy access to megabytes to suit the growth of the F-22 program. The company mainly uses CFD technology to supplement the F-22 wind tunnel test work, such as selecting the appropriate layout for wind tunnel test; diagnosing airflow phenomenon. The CFD can also provide companies with more aerodynamic data based on the F-22 tests and solve problems that are too complex and expensive to utilize wind tunnel testing techniques.
