Hypersonic waveriders have a large flight envelope, leading to the difficulty in keeping overall flight stability for a fixed geometry.\nAccordingly, hypersonic waveriders can be considered to design as a morphing vehicle such that the flight range is expanded\nfor waveriding stability. To this end, this paper investigates the collaborative deformation design using control integrated analysis\nmethods for the hypersonic waverider. Firstly, a parametricmodel is applied to combine the shape deformationwith the geometrical\nproperties. Secondly, the morphing process with regard to the change in a single geometric parameter and the static and dynamic\ncharacteristics affected by this deformation are analyzed. Afterwards, the collaborative relations are discussed for the changes in the\nlower forebody angle and elevon area. Furthermore, a flight control law is designed to guarantee flight stability while implementing\nthe collaborative deformation, and the morphing results are evaluated based on the control-oriented idea. Finally, a simulation\nexample is used to verify the effectiveness of the proposed methods for the hypersonic waverider.
