大型客机总体设计准则与概念创新

 从研制中国未来具有全球市场竞争力的大型客机为出发点，结合波音和空客下一代大型客机的研究思路以及美国和欧洲近年来围绕大型客机的若干重大研究计划，较深入地分析了在我国的大型客机的研制中实现安全性、经济性、舒适性和环保性总体设计思想的重要性和必要性。在此基础上，就如何建立大型客机综合考虑安全性/经济性/舒适性/环保性设计与评价准则体系，评价思路与方法进行了探索和研究，这对我国大型客机的研制具有借鉴意义。此外，依据详实的数据，分析了2种新概念布局方案，即“BWB-C”型翼布局方案和“大载重浮升式飞机”方案，与目前常规布局方案飞机优缺点，同时分析了应用多学科精细设计方法对于提高大型客机飞机经济性的效果。在此基础上，指出了概念创新和多学科优化精细设计方法大规模应用对于提高大型飞机安全性/经济性/舒适性/环保性的重要意义。

The Study of Concept Design Criteria for Large-scale Passenger Aircraft with New Technologies

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.
