Abstract:The flight dynamic characteristics of Airbreathing Hypersonic Flight Vehicles (AHFV) are quite different from the traditional flight vehicles due to the hypersonic speed regime and the integrated design of waverider airframe and airbreathing sramjet. The process of designing the vehicle or its control system involves the novel dynamic characteristics of AHFVs, so it is crucial to establish a new class of vehicle-dynamic model that sought to identify critical issues in flight dynamics of AHFVs. A review is presented with the focus on the contributions to the development of this new model. First, a brief history of AHFVs from the scramjet research stage to system research stage is outlined. After that, the brand new flight dynamic characteristics of AHFVs are elaborated, including wide flight ranges, effects of hypersonic speed, constraint of scramjet, airframe/propulsion interaction, effects of aeroelasticity. Then followed by a discussion on problems and possible solutions encountered in modeling the flight dynamics of AHFVs, which can be divided into the following steps: selection of coordinate system, abstraction of the vehicle shape, modeling the elastic airframe, modeling the aerodynamics, modeling the scramjet system and derivation of the equations of motion. In the end, Some comments and future directions on modeling the flight dynamics of AHFVs are addressed.
