英文摘要: This project will study the gliding maneuver trajectory planning approaches based on the evolved drag acceleration flight profile in order to solving the problems of multiple constraints, maneuver mission requirements, and the uncertainty of the parameters in the flight of the hypersonic vehicle. Firstly, the model of gliding maneuver trajectory planning with multiple constraints will be built, which provides the basis for the study of planning approach. Then, the design approaches of three-dimensional gliding maneuver flight corridor will be studied, and both the generation strategy of the evolved drag acceleration flight profile and the rapid prediction of maneuver capability based on the profile can also be proposed. Thirdly, multiple maneuver models will be built considering the real applications, and the corresponding maneuver strategy can be designed, based on which we can propose the gliding maneuver trajectory planning approaches satisfying the requirements of multiple maneuver missions; Lastly, in order to solve the problem of the uncertainty of the parameters in guidance, a three-dimensional “conservative flight corridor” will be built, and the flight profile can be designed and optimized in the conservative corridor. Hence, the 3D trajectory can be completed by following the flight profile. This project aims to solve the key problems in gliding maneuver trajectory planning for hypersonic vehicles and to provide a theoretical basis and technical support for its further development. The research work can also provide a technical reference for the reentry of missile, reentry of airship, landing on the moon and the exploration of the Mars.
