全球化的市场竞争是商用飞机产业的重要特征之一,对安全性、舒适性、经济性和环保性指标的不断追求推动着技术的不断进步及产业链的全球化发展。在飞机设计中,对经济性的考虑在航空技术和型号发展中的作用越来越突出,也是中国航空产业发展面临的重大挑战因素之一。在新技术研发决策及其在型号中的应用中,经济性考虑始终是决策的关键因素,本文综述航了空经济学的研究范畴和主要分析方法,及其对飞机概念设计、结构设计和系统选择等主要决策的影响,面向价值的设计理论和方法在飞机设计中的实践。希望本文的发表可以促进航空经济学的发展,相关方法可以在型号设计的最优综合评价中发挥作用,实现涵盖时间成本在内的综合评价指标最优的方案。可以预期,航空经济学的发展有助于提升中国航空制造业在竞争越来越激烈的全球航空产业链中的竞争力。
Global competition in the market is one of the important characteristics of the commercial aircraft industry. The continuous pursuit of safety, comfort, economy and environmental protection indexes has promoted the continuous improvement of technology and the globalization of the industrial chain. In aircraft design, the economic considerations become more and more prominent in the development of aviation technology and model. It is also one of the major challenges for the development of China’s aviation industry. In the new technology research and development decision-making and its application in the model, economic considerations are always the key factors in decision-making. This paper reviews the research scope and main analysis methods of aeronautics and astronautics, as well as its impact on aircraft conceptual design, structural design and system Choice and other major decisions, the design of value-oriented theory and methods in aircraft design practice. It is hoped that the publication of this article can promote the development of aviation economics. The related methods can play an important role in the optimal comprehensive evaluation of model design, and achieve the optimal comprehensive evaluation index covering the time cost. It can be expected that the development of aviation economics will help enhance the competitiveness of China’s aviation industry in the increasingly competitive global aviation industry chain.
