英文摘要：

The wave-rider is a kind of aerodynamic shape for hypersonic vehicle, as a result of high lift- drag rito and maneuvering capacity. Hypersonic vehicle has the characteristics of strong coupling, nonlinear and large envelope flight, flight performance can be optimized by introducing intelligent morphing technolo- gy which can change vehicle configuration with flight states in wave-rider conceptual design. In this paper, a nonlinear mathematical longitudinal model of a hypersonic vehicle is established with its geometry provid- ed to estimate aerodynamic force and thrust by using hypersonic aerodynamics and quasi-one-dimensional flow with heat added. By analyzing the change of sramjet engine performance and wave-rider aerodynamic characteristics to vehicle configuration, the rule of morphing based on the engine performance is given. A classical decentralized inner-outer loop control system is introduced to stable morphing wave-rider and the reference command is tracked.
