与同量级常规布局飞机相比,翼身融合布局(BWB,Blended wing body)飞机具有结构重量轻、气动效率高、燃油消耗少等优势,被普遍认为是最有希望应用到下一代民机的新型气动布局。通过与常规布局飞机机身结构的比较,对BWB非圆柱形机身结构特性进行了分析研究,并在圆柱多舱段机身(MBF,Multi-bubble fuselage)的基础上进行了翼身融合布局增压舱的结构设计,提出了两种增压舱结构型式。结构分析表明球形增压舱是一种结构较为高效、空间利用率较高的结构型式,为BWB增压舱结构设计提供了重要参考。
Compared with the same-class conventional layout aircraft, the BWL (Blended wing body) aircraft is characterized by its light weight, high aerodynamic efficiency and low fuel consumption. It is generally considered to be the most promising application to the next generation of civil aircraft The new aerodynamic layout. Through comparing with the structure of conventional aircraft fuselage structure, the structural characteristics of BWB non-cylindrical fuselage are analyzed and studied. Based on MBF (Multi-bubble fuselage) fuselage fuselage layout The structure design of the pressurized cabin, proposed two types of pressurized cabin structure. Structural analysis shows that the spherical turbocharger is a structure with high efficiency and high space efficiency, which provides an important reference for the design of BWB turbocharger structure.
