摘要
介绍计算机辅助设计系统的概念及基本要求，以及计算机辅助飞机总体方案设计系统的特点与要求。模型问题是建立系统的首要问题，根据设计理论的概念，建立了设计对象模型及设计过程模型。设计对象模型用于综合所有设计工具；设计过程模型用于描述设计过程与设计活动。通过飞机总体参数选择阶段系统的开发，说明所建立的模型是正确的、有效的。
he concept and basic requirements of computer aided design,the characters and requirements of computer aided aircraft conceptual design system are described The first thing in developing a design system is to create the models.Design object model and design process model according to the design theory are established. The design object model is applied to integrating all design tools,and the design process model is applied to describing design process and design activities.The correctness and effectiveness of the established model have been testified through the development of aircraft conceptual parameter selection system.
