Shen Zhang(Aircraft CAD Research Center, Beijing University of Aeronautics andAstronautics, Beijing, China, 100083)
The concept and basic requirement of computer aided design, the charac-ters and requirements of computer aided aircraft conceptual design system are describedin this paper. The first thing in developing a design system is to create the models. A de-sign model and a design process model are estabhshed according to the design theory.The design object model is applied to integrating the design tools, and the design pro-cess model is applied to describing design process and design activities. The correctnessand effectiveness of the established models have been testified through the developmentof an aircraft parameter selecting system. Further work is still going on, and the abovemodels will continue to be testified in it.
