摘要
未来航空运输市场对大型民机提出了更严苛的要求,采用翼身融合构型成为提升未来民机综合性能的重要发展方向,引起各大飞机厂商和科研院所的广泛关注。从布局变革、方案演变以及关键技术成熟度提升等多方面出发,比较详细地论述了欧美各国在翼身融合方案设计领域的探索研究工作。重点对美国N+2/N+3计划、欧盟第五框架计划中研究的多个主流方案进行分析,并对其中涉及到的系列化、应急撤离、动力集成以及气动设计等问题的研究现状进行了阐述,介绍了各方案针对上述技术问题的解决方式和思路。最后总结了翼身融合布局在未来大型民机上应用所面临的挑战,并对新构型的发展趋势以及前景进行了展望,对我国未来民机新构型方案的发展具有一定的参考价值。
The future air transport market has put forward higher requirement for large civil aircraft.Adopting BWB(blended-wing-body)configuration has become the potential development direction to improve the comprehensive performance of future civil aircraft,which has attracted extensive attention from major aircraft manufactures and scientific research institutes.From the configuration evolution,program promotion and maturity improvement of key technologies,this paper discusses in detail the exploration and research work in the field of BWB design in European and American countries.This paper focuses on the analysis of several mainstream schemes in the American N+2/N+3 program and the fifth framework program of the European Union,and expounds some involved significant problems,such as serialized design,emergency evacuation,power integration and aerodynamic design,and introduces the solutions and ideas of each scheme for the above problems.Finally,the challenges faced by the application of BWB in future large civil aircraft was summarized,and the development trend and prospect of BWB configuration were prospected.The research content of this paper has certain reference value for the development of new configuration scheme of future civil aircraft in China.
