| Abstract: |
| Waverider configurations applied to hypersonic vehicle will bring new challenges for its model study, which mainly consider mutual couplings in aerodynamic、propulsion and control effects should be considered enough in the modeling process. Therefore, it is necessary to introduce a new method to study the hypersonic vehicle model in order to ensure the accuracy of the model. Based on the theory of hypersonic aerodynamics, this paper proposes a new method for hypersonic longitudinal model, including using oblique shock wave theory、Prandtl-Meyer relation and Rayleigh flow principle to estimate aerodynamic force and thrust of hypersonic vehicle, establishing its non-linear mathematical longitudinal model, and analyzing its aerodynamic characteristics of longitudinal motion in different trim points in order to grasp the characteristics of hypersonic flight and provide good object for the design of control system. Simulation studies show this method is feasible to longitudinal model of hypersonic vehicle. |
