Abstract:

Technology is a basic impetus on the development and evolution of the civil aircraft aerodynamic configuration.In order to study the development directions,technical requirements and strategies for the future civil aircraft,this paper reviews the development of civil aircraft aerodynamic configuration and then summarizes four technical factors,i.e.,aeroengine,aerodynamic design,structural design and flight control,which have important influence on the formation and evolution of the modern civil aircraft aerodynamic configuration.The role of these technical factors in the development of the civil aircraft aerodynamic configuration has also been revealed.Considering the new requirements for the future air transportation,this paper points out the main developing directions of the future civil aircraft,and emphatically analyzes the aerodynamic configurations such as blended wing-body,double bubble body,braced-wing and joined-wing,which might be used in the future unconventional civil aircraft.Furthermore,the challenge in technology development,as well as the technology strategies for the future civil aircraft conceptual design,has been discussed.Finally,the paper clarifies that the multidisciplinary design optimization is an effective method for the future civil aircraft conceptual design.

Key words: air transportation, civil aircraft, aerodynamic configuration, conceptual design, technical factors
