采用虚实融合和协同工作技术进行大型装备的设计论证和辅助拆装维护是工程科技发展的一个新方向。面向我国自行设计生产商用大飞机的需求，在863计划支持下，正在研制用于驾驶舱布局设计和飞机关键部件辅助拆装维护的虚 实融合协同工作环境CAR-CA（collaborative augmented reality for commercial aircraft design & maintenance）。概要介绍CAR-CA的工程技术研究进展，包括体系结构、系统组成、关键技术研究和系统的应用前景等。

It is a new aspect of engineering science that uses augmented reality and collaboration technology to aid the design and maintenance of large equipment. To meet the requirement of the design and manufacture of commercial aircraft in China, CAR-CA(collaborative augmented reality for commercial aircraft design & maintenance) is under development now to aid the cockpit design and training of components disassembly and assembly. This paper introduced the engineering and technology progress of CAR-CA, including the system architecture, system components, technology researches and system application prospect, etc.
