Abstract:

Based on a study of Boeing and Airbus Corporations’ plans for a new generation largescale passenger aircraft and some very important technology development research projects for largescale passenger aircraft in America and Europe, this paper proposes a view of China’s largescale passenger aircraft development in the context of global commercial competition in terms of research, safety, benefitcost characteristics, cabin comfort, and environment friendliness. Furthermore, it presents the basic concept design criteria for China’s largescale passenger aircraft, involving safety design, benefit-cost design,cabin comfort design,and environmental protection design.Seven examples are given to illustrate the contribution of new technologies to large-scale passenger aircraft,,including BWB-C passenger aircraft,aircraft-airship for large or heavy cargo,and 5 fine designs of aerodynamics,structure,auxiliary power unit,hydraulic system,and multidisciplinary design analysis and optimization.
