Abstract: To shorten the design period of airplane,improve the design quality and reduce the manufacture cost,the computer supported cooperative design has become one of the effective methods．In order to realize the airplane cooperative design in multi-discipline integrated research processes,cooperative design system architecture based on double buses is presented．In which the web service bus was adopted to integrate the software platforms with different frameworks and the agent bus was adopted to integrate the software platforms with the same framework．On the base of the cooperative design system architecture,an aircraft cooperative design system is established by integrating the workflow system and CAD system．

Key words: Computer-supported cooperative design,Web service,Agent system,Airplane design
