支线客机关键技术与发展方向

Key technology and future development of regional airliner

支线航空作为公共运输航空的一个重要组成部分,随着市场需求的激增和国家政策的扶持,即将进入高速发展期。支线客机作为支线航空市场中的核心技术产品,不仅是打开全球支线飞机市场的钥匙,更是体现大国经济和科技实力的重要名片。基于支线客机的发展历程,深刻剖析了支线客机的任务使命,对支线客机总体气动、动力、机载系统这3方面的关键技术进行了详细阐述,并结合商用飞机的发展,讨论了支线客机的技术发展方向;最后基于未来发展需求,提出了基于自动、自主和智能化的支线客机任务系统概念。

With the surge in market demand and the support of national policies,regional aviation is about to enter a period of rapid development.As a core technology product in the regional aviation market,the regional airliner is not only the key to the global regional market,but also an important business card that reflects the economic and technological strength of the country.Based on the development history of the regional airliner,this paper analyzes the missions of the regional airliner,and elaborates on the three key technologies including overall aerodynamics,powerplant systems,and airborne systems.Then,the technical development direction of regional airliners is discussed in the context of development of commercial aircraft.Finally,according to the future development needs,the concept of regional jet airliner mission system characterized by automation,autonomy and artificial intelligence is proposed.
