| Abstract: | Blended-Wing-Body(BWB)aircraft is a tailless large transport with high lift-drag ratio,and the aerodynamic study for BWB aircraft is a basis of overcoming the technology challenges about it.Firstly,research history on BWB configuration is presented in this paper;geometric parameters and basic performances of BWB configuration are discussed;and wind tunnel experiments and free flight tests for large BWB aircraft are described.Secondly,multidisciplinary optimization design technologies applied to the BWB aircraft,especially aerodynamic optimization design technologies,which are one of basic ways for solving BWB aerodynamic problems,are discussed.Thirdly,major issues of BWB configuration research,such as aerodynamic characteristics,aeroelastic design and integrated engine/body design,are given.Finally,some further works about BWB configuration study are proposed. |
