翼身融合布局客机客舱布置快速生成原型系统

翼身融合布局（BWB）客机的客舱布置方案在很大程度上决定了其气动外形，筛选出一种合理的客舱布置方案是BWB客机概念设计的一项重要任务。为了提高BWB客机客舱布置设计的效率，应用基于知识工程（KBE）的方法，将BWB客机客舱布置的知识和规范融入在客舱布置几何模型创建过程中，开发出了一个BWB客机客舱布置快速生成的原型系统。分别以300座和400座BWB客机为例，验证该原型系统的有效性。结果表明，只需输入客舱布置设计要求和主要参数，该原型系统即可自动地生成客舱布置方案。所开发的原型系统为BWB客机客舱设计提供了一种快速的途径。 

A prototype for rapid generation of cabin layout of blended wing body aircraft

The aerodynamic shape of the blended wing body (BWB) aircraft is largely determined by the cabin layout, and thus designing a reasonable cabin layout is very important in the BWB aircraft conceptual design. In order to improve the efficiency of cabin layout design for BWB aircraft, a prototype for rapid generation of cabin layout was developed based on knowledge based engineering (KBE) method by integrating the knowledge and specifications of cabin layout into the process of geometric model generation of the cabin layout. The cabin layout designs for the BWB passenger aircraft with 300 seats and 400 seats were used as the examples to illustrate effectiveness of the prototype. The results show that the cabin layout schemes can be automatically generated using the prototype once the requirements and key parameters of the cabin layouts are given. The prototype can be used as a rapid tool for the cabin layout of BWB aircraft.
