翼身融合布局非圆截面客舱结构特性分析

摘要

The force properties of non-circular cross-section cabin structure of the unique blended-wing-body configuration is studied and compared with the force properties of the traditional structure of circular cross section. The improvement program of non-circular cross-section cabin structure of the blended-wing-body configuration is studied primarily, and two improved method are advanced which are the use of arc-shaped tran-sition and the use of “Y” type of strengthening the pillars of the method. In the design of the blended-wing-body configuration of noncircular cross section, the combination of these two methods can substantially increase the weight of non-circular cross-section cabin efficiency, space utilization and economy.%研究了翼身融合布局特有的非圆截面客舱结构的受力特性,并与传统圆截面客舱结构的受力特性进行对比.对翼身融合布局非圆截面客舱结构的改进方案进行了初步研究,提出了两种改进方法,即采用圆弧形过渡和使用"Y"型加强支柱的方法.在翼身融合布局非圆截面客舱结构设计时,结合这两种方法,可以充分提高非圆截面客舱的重量效率、空间利用率和经济性.
