中国的商用大飞机项目近几年取得了长足的发展,宽体客机也已立项,但是面临严峻的市场考验和成本压力,只在满足适航规章的前提下获得技术成功是不够的.商用飞机的经济性成为了飞机能否为制造商和用户带来合理利润,最终取得商业成功的最关键因素.为了探索飞机经济性设计,本文在介绍价值驱动设计定义与流程的基础之上,比较价值驱动设计与传统系统工程的区别,并将价值驱动设计理念应用到民用客机概念设计阶段,为探索该阶段经济性设计方法提供支撑.%China commercial aircraft project has achieved great development in recent years and the wide-body aircraft project is started. However, facing the severe market challenge and cost pressures, it is not enough to achieve technical success under the condition of satisfying the airworthiness regulations. The commercial aircraft economy has become the most critical factor to bring reasonable profit to the manufacturer and users and achieve commercial success finally. In order to explore the aircraft economy design, this paper introduces the definition and the process of value driven design and compares the difference between value driven design and traditional system engineering. In order to support the exploration of economy design method in conceptual design stage, the concept of value driven design is applied to civil aircraft conceptual design stage.
