虚拟风洞是虚拟现实技术和ＣＦＤ技术在飞机设计和改型中的应用。本文分析了虚拟风洞的工作流程，并针对国内相关硬件水平提出了一个分布式虚拟风洞结构设计方案。在此结构上，完成了负载的合理分配。最后，以一个典型ＣＦＤ应用为例分析了分布式虚拟风洞系统的硬件要求和性能。
Virtual wind tunnel is the application of virtual reality technology and CFD technology in aircraft design and modification. This paper analyzes the work flow of the virtual wind tunnel and proposes a distributed virtual wind tunnel structure design plan according to the domestic relevant hardware level. In this structure, the rational allocation of load is completed. Finally, a typical CFD application is taken as an example to analyze the hardware requirements and performance of the distributed virtual wind tunnel system.
