摘要

中国大型客机研制过程中追求"三减，四性"：减阻、减重、减排，安全性、经济性、舒适性、环保性。中国大型客机采用翼下常规布局形式，放宽静稳定技术，发动机选用CFM公司Leapx-1C发动机，这对气动设计技术在工程适用性上提出了极高的要求。大型客机是中国第1架完全自主知识产权民用飞机，本文综述了其设计过程中采用的先进气动优化设计方法、CFD分析和充分的风洞试验验证，说明了超临界机翼设计、高效增升装置设计、飞机/发动机一体化设计、尾翼设计、翼梢小翼设计和部件精细化减阻设计技术，能实现大型客机的减阻应用设计。研究表明，中国大型客机在气动设计水平和设计方法上取得了一系列的进展和突破，实现了设计具有较强竞争力的先进民用飞机的目标。

Abstract

In the development of civil aircraft in China, a large passenger aircraft aims at achieving "three reductions", drag reduction, weight reduction, and emission reduction as well as "four performances", safety, economy, comfort, and environmental protection. The aircraft adopts the conventional wing-nacelle layout, broadening the static stability and using the CFM Leapx-1C engine. These requirements put extremely high demands on the engineering applicability of aerodynamic design technology. Large civil aircraft is China's first civil aircraft that owns completely independent intellectual property rights. This paper reviews the advanced aerodynamic optimization design method, CFD analyses, and abundant wind tunnel verification tests used in the design process of the aircraft. Based on the works mentioned above, researchers used many technologies on the aircraft to reduce the drag, which contains supercritical wing design, efficient high-lift-device design, wing-nacelle integrated design, empennage design, winglet design, and refined drag reduction for components. This paper shows that it has made a series of progresses and breakthroughs in aerodynamic design capability and design method, achieving the goal of designing advanced civil aircraft with strong competitiveness.
