Collaborative Deformation Design Using Control Integrated Analysis Methods for Hypersonic Waverider

Abstract EN

Hypersonic waveriders have a large flight envelope, leading to the difficulty in keeping overall flight stability for a fixed geometry.

Accordingly, hypersonic waveriders can be considered to design as a morphing vehicle such that the flight range is expanded for waveriding stability.

To this end, this paper investigates the collaborative deformation design using control integrated analysis methods for the hypersonic waverider.

Firstly, a parametric model is applied to combine the shape deformation with the geometrical properties.

Secondly, the morphing process with regard to the change in a single geometric parameter and the static and dynamic characteristics affected by this deformation are analyzed.

Afterwards, the collaborative relations are discussed for the changes in the lower forebody angle and elevon area.

Furthermore, a flight control law is designed to guarantee flight stability while implementing the collaborative deformation, and the morphing results are evaluated based on the control-oriented idea.

Finally, a simulation example is used to verify the effectiveness of the proposed methods for the hypersonic waverider.
