Abstract: This paper brings forward a method based on parameters to model aliform components in conceptual aircraft design. The method aims at the character of component, and was constructed on the basis of object oriented technology in order to meet the requests of the needs of conceptual aircraft design. This method unifies the parameters of aliform components. It has the capacity to define the shape of the component accurately and uniquely by a few parameters. It makes it easier to share the model within multidisciplines by using the uniform parameter. The production of synthetic design becomes more nice and reliable. The quality and efficiency of conceptual aircraft design are improved.
