Abstract : A jetfighter shape modeling method based on design features is researched, to improve the efficiency of shape modeling in
the stage of conceptual aircraft design. The aircraft¡¯s general design features and shape parameters, including geometric and
position parameters, are described. The coordinate systems of the entire aircraft and its components are defined. As a sample
of local shape, a method of inlet intake modeling is introduced. The whole process of the modeling method is proposed. Three
examples of different jetfighters are listed, to describe the achievement of basic layout, which includes four main elements. The
Fusion of Components can be achieved by regulating the details of the sections of the fuselage. Sample Cases of typical layouts
are shown to verify the effectiveness of the proposed method, which provides the basis for further analysis and optimization.
