The invention provides a hypersonic deformable waverider and a dynamic modeling method thereof, which are different from a traditional deformable aircraft modeling method which only considers a symmetric deformation model and only based on a single rigid body hypothesis, and are characterized in that a fuselage and two wings are used as three rigid bodies for modeling; the multi-rigid-body characteristic formed by the fuselage and the wings on the two sides is fully considered, and multi-rigid-body modeling of the wave rider with the variable elongation is achieved; meanwhile, the model constructed by the method comprises additional force and additional torque items caused by wing expansion deformation, can reflect symmetric and asymmetric deformation characteristics of the aircraft wing, and is clear in physical significance and high in model intuition; that is to say, the hypersonic-speed variable-elongation waverider model constructed by the method has good adaptability, and a solid foundation is laid for researching related problems such as guidance and control of the hypersonic-speed variable-elongation waverider.

    本发明提供一种高超声速可变形乘波体及其动力学建模方法,不同于传统变形飞行器只考虑对称变形的模型以及仅基于单刚体假设的飞行器建模方法,本发明将机身和两片机翼作为三个刚体进行建模,充分考虑了机身和两侧机翼所构成的多刚体特性,实现了可变展长乘波体进行了多刚体建模;同时,本发明所构建的模型中包含由于机翼伸缩变形所引起的附加力和附加力矩项,能够反映飞行器机翼对称和非对称变形特点,物理意义明确,模型直观性强;也就是说,本发明所构建的高超声速可变展长乘波体模型具有较好的适应性,为研究高超声速可变展长乘波体制导、控制等相关问题奠定了坚实基础。
