Integrated Modeling Method Including Aerodynamics And Radar Stealth Of Winged Missile Conceptual Design

This paper presents an integrated design method based on system engineering theory to meet the diversification and high standard requirement of modern aircraft by apply product design theory in aircraft design, the process control of design become more rational. During the function decomposition, the integration design flow of aerodynamic configuration and stealth in cruise missile conceptual design can be established, and in this process, this paper implement the reduction of coupling and uncertainty in design to decrease the difficulty of the design and shorten the design cycle time. The established design flow helps to propose and verify modeling parameters, and to make good use of these parameters in conceptual design, the paper use quick modeling method to build unified model between disciplines. Then the result of MDO shows that the integrated modeling method improves the design efficiency and design quality.
