摘要:The development of standard model for a civil single-aisle passenger aircraft is significant for the advancement of CFD simulation and wind tunnel test.Not only can it be used to validate the credibility of CFD simulation,promote the progress of CFD technology,provide a reliable tool for aerodynamic shape design,and also can it be used to validate the quality of wind tunnel test,correct measuring instruments,develop advanced measuring method,and improve calibration method for the interference from wind tunnel wall/support.The aerodynamic shape design of a standard model CHN-T1 is presented for wind tunnel test and applied CFD credibility validation,which is composed of wing,body,horizontal-tail,vertical-tail,nacelle,pylon and so forth.The wing is optimized in detail,together with a single-aisle fuselage,horizontal and vertical tails meeting the typical stability and control requirements, a flow-through nacelle installed under the wing with a pylon.Those components constitute the clean configuration, whose geometric feature is representative of a contemporary single-aisle passenger aircraft.The model is designed to fly at a cruise Mach number of Ma=0.78 with a nominal lift coefficient of CL=0.5.Supercritical airfoils are employed to develop the wing,thus good aerodynamic characteristics is achieved with and without the nacelle/pylon group.Relevant information can provide reference support for the 1 st Aeronautics CFD Credibility Workship(AeCW-1 ).%发展单通道客机标模,特别是针对国内客机研制的标模,一方面利于确认CFD软件计算的可信度,从而促进CFD软件能力提升,为客机气动外形设计提供可靠的分析工具;另一方面有利于确认风洞试验品质,校对测量仪器,改良干扰修正方法,研发先进测量技术.本文介绍了用于确认风洞试验和CFD可信度的标模CHN-T1的气动外形设计.该标模包含机身、机翼、平尾、立尾、短舱、吊挂等部件.对机翼开展了详细优化设计,并配置单通道的窄体机身、满足稳定控制需求的平尾和立尾、翼下吊挂的通气模型短舱,组成全机干净构型,具有现代单通道客机的典型几何外形特征.标模设计马赫数为0.78,设计升力系数为0.5.机翼采用高气动效率的超临界翼型,在有/无短舱/吊挂组件的影响下,机翼均展示了良好的气动性能.相关信息可为即将召开的"第一届航空CFD可信度研讨会(AeCW-1)"提供基础.
