| 摘 要： | 主要研究了翼身融合飞机结构受力,讨论了BWB结构与传统飞机结构最主要的区别,提出了一种新的BWB非圆形截面结构.通过计算分析,比较了圆形截面、矩形截面以及混合型截面三种不同结构受力.计算结果表明,在满足重量限制的条件下,混合型结构是一种高效的非圆柱BWB结构.该结构减小了结构所承受的弯曲应力,提高了BWB飞机结构的安全性.

| Abstract: | The stress of Blended-Wing-Body(BWB) structure is studied,discussed the main differences between BWB and conventional cylindrical fuselage,and proposed a new non-cylindrical fuselage structure of BWB.The stress of the circle section,the rectangular section and the mixed section are compared through computation and analysis.The computing result demonstrates that the mixed section is a better non-cylindrical structure of BWB.This structure reduces the stress and increases the security of the BWB. |
