Abstract: | The plane-symmetric configuration has been widely used for new flight vehicles to achieve a wide-velocity-range and large-space flight. However, large flight amplitude and speed arrange result in poor stability and uncontrollable flight. In this paper, the lateral-directional coupling was comprehensively considered in the flight vehicle design, and a multidisciplinary designing method was presented. By the aid of this designing method, a quantitative study of the design parameters for the stability and performance parameters can be conducted, which can further support optimization of the overall design. |
