摘　　要：按照CFD软件模拟的流速范围、流动特征对CFD软件的可信属性进行划分,形成亚、跨、超、高超流动模拟指标以及所对应的流动特性模拟能力指标,得到CFD软件可信度评价指标;并结合所对应的指标设计出基准级、部件级和系统级三级度量元,制定出CFD软件可信度评价准则和评价方法,建立起一套可用于评价航空CFD软件可信度的评价流程和评价体系。According to the range of flow speend and the flow characteristics of CFD software simulation , the reliability qualities of CFD software which include the subsonic ,transonic,supersonic and hypersonic flow are achieved .Based on the different level of evalation indexes ,the three different measurement units are designed and the rules and methods of evaluating are established .At last,an evaluation index system of CFD software reliabilty and evaluation process are consituted in the paper .
