摘要: 为了在飞机概念设计阶段有效而便捷地评估方案重量和静稳定裕度等特性,研究了在一个按照面向对象方式进行数据组织的计算机辅助飞机概念设计系统中进行重心及相应重量估算的措施.着重论述了重心估算部分的面向对象结构和采用的方法,尤其是根据相关部件的设计与造型特点估算燃油及起落架重心的方法.通过在设计方案的动态调整过程中估算其重量和重心,验证了该部分的适应性和可靠性,以及设计者交互地对估算的方法和结果加以控制的灵活性.

Abstract: In order to evaluate such characteristics as weight and static stability of proposed concepts effectively and conveniently during aircraft conceptual design, the implementation of center of gravity and associated weight estimation in an computer aided aircraft conceptual design system, whose data organization is object oriented, was studied. The emphases were placed on the object oriented structure of center of gravity estimation and methods adopted in this part, especially the methods of estimating center of gravities of fuel and landing gear based on the design and modeling of relevant components. Through conducting weight and center of gravity estimation during the process of dynamic adjustment of concepts, the adaptability and reliability of this part, as well as the flexibility of designers’ interactive controls on estimation, were validated.
