摘要

总结了第一届航空可信度研讨会（AeCW-1）的数值模拟结果。AeCW-1会议由中国空气动力学会计算空气动力学专委会主办，并在第一届空气动力学大会上做了专题研讨。本次研讨会吸引了14家单位参与，共提交了26组计算结果。活动的主要目的是针对典型运输机巡航构型，评估国内CFD当前技术状态，探索CFD进一步发展的研究方向，促进CFD验证和确认工作的开展，为大型客机的研制提供技术支撑。AeCW-1选择的研究模型为中国空气动力研究与发展中心（CARDC）设计的单通道运输机模型（CHN-T1），CHN-T1包括机身/机翼/平尾/立尾等部件，分别在CRADC的2.4 m×2.4 m风洞（FL-26）、欧洲的2.4 m×2.0 m风洞中（European Transonic Wind Tunnel，ETW）开展了风洞试验。AeCW-1组委会提供了系列结构网格和非结构网格，研究工况主要包括网格收敛性研究、抖振特性研究、雷诺数影响研究，风洞模型支撑装置和静气动弹性变形对数值模拟结果的影响是重要的研究内容。本文对提交组委会的数值模拟结果进行统计分析，并与FL-26及部分ETW的风洞试验结果进行了对比，对未来的研究工作提出了意见和建议。

Abstract

Numerical results from the first aeronautical computational fluid dynamics credibility workshop (AeCW-1) are summarized. AeCW-1 is organized by the CFD professional committee of the Chinese society of aerodynamics

in conjunction with the 1

Chinese conference of aerodynamics. A total of 26 data sets were submitted from 14 different institutions. The premise of AeCW-1 is to assess the state-of-the-art of modern CFD technology in China

identify areas needing additional research and dev

elopment

promote the progress of CFD verification and validation

and provide technical support to the development of large airliner. The CHina-transport 1 (CHN-T1) as the subject geometry in wing-body-tail form

which is a single-aisle airliner developed by CARDC and represents a modern transonic commercial transport airplane. The CHN-T1 has been tested in CARDC 2.4 m×2.4 m transonic wind tunnel (FL-26) and 2.4 m×2.0 m European transonic wind tunnel (ETW). The AeCW-1 organizing committee provides a series of structured and unstructured grids

and the official test cases include the grid convergence study

the buffet study and the study of Reynolds number effect. The influence of the wind tunnel model support system and static aeroelastic deformation on the numerical results are the main concerns. This paper presents statistics analyses of the submitted numerical results and their comparisons with the experimental data from FL-26 as well as some data from ETW. These analyse lead to enables us to give some thoughts and suggestions for the future research activity.
