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.
